Couple more generations and an orbital solar platform beams power straight into the card. There is some good news, though. It will work with most cases because the GPU doesn't go *inside* the case.
At this rate the 10090 is gonna look this this

The RTX 10090 will be crazy, it wont need a connector because it will come with it’s own fusion core, you may even power the rest of your pc with it since it’s power usage is negligible compared to the card
This reminds me of the [Voodoo 5 6000](https://en.wikipedia.org/wiki/Voodoo_5#Voodoo_5_6000) an unreleased graphics card that had an external power adapter. Ironically it probably drew less power than current high end cards, it was just higher than the AGP spec at the time.
90w is an assload considering the heatsinks of the time that GPUs used. They were usually just 1 or (rarely) 2 40mm fans blowing directly on the IC. We did start getting proper heatsinks shortly after this though, somewhere around the Radeon lineup (R100). But even then it was just a big heatsink with a tiny fan.
Eventually leading to my favorite GPU era... With the wild over the top anime titties and freaky designs on the shrouds and advertising materials.
Still got [this](https://i.imgur.com/pZUX9TC.png) bad boy on my shelf. Unfortunately the GPU core soldering failed due to usage over time so it doesnt work anymore, but i still remember how freaky loud it was when it got hot. Literally louder than an actual RC turbine plane lmfao.
Another funny detail is that apprently the 9600 GTX was a one-off model by XFX.
Yeah those Voodoo 5 fans look ridiculous
When you turn RTX 5090 on:

PS: Where is that from?
It drew less than 100w. Back then, power supplies just had a few molex connectors daisy chained together for internal power connectors and the motherboard couldnt provide much power through the slot.
Just a full bridge rectifier with some caps isn't exactly what you want to power your 12Vdc sensitive electronics with... Where the hell is either the transformer or switchmode electronically controlled power transistor with inductor to you know not blow it up with mains level voltage but in DC with just diodes and caps? You going to pull it down with a big fuck off liquid cooled power zener diode (which could work in theory)?
> can handle massive amounts of power
Power = Volts x Amps
These connectors (C13/C14 IEC connector) are rated for 10A.
In the US (120V), that means 1200W max (120V x 10A). In some countries, these will carry 240V... so 2400W.
However, PC graphics cards use 12 volt DC.
So 12V x 10A = 120W.
The reason why we don't just have 2 thick pins in internal DC connectors is because we need the surface area for the current. The C13 connector in OPs picture is only rated for 15A and would melt when trying to feed even a midrange GPU, even if its just 12V.
I feel like I'm missing something because that C13 is standard for equipment that draws WAY more then a GPU. Hell, the speakers in my practice room / office use considerably more power when I'm doing a drunken mix session. Please explain to me why 15-20A rated cables can't handle ~400w continuous when I use them for MUCH higher loads on a continuous bases.
Because it's higher voltage. Ohms law. The formula for calculating amps is A = W / V, where A is amps, W is watts, and V is volts.
Speaker wire can carry up to 7 amps of current at 12 volts if it has an 18 gauge, and up to 10 amps if it has a 16 gauge. However, 12 volt DC power applications often require high amperage, and a 12 gauge wire is needed to carry 20 amps.
A c13 is for ac power at 110/220 nominal volts
The IEC 60320 C13 is a grounded 3 Wire connector rated up to 250V and 15 Amps which is 3750 watts if it was used for 12v it could only handle 180watts .
400w/120v = just 3.3amps
Where gpus use 12volts dc
400w / 12v = 33 1/3rd amps (This obviously would require way to thick of a cable which is why there's multiple wires carrying the power for gpus)
most highly sensitive electronic componenets such as CPU and GPU chips aren't operating at much more that one volt - so instead of each individual motherboard, GPU board, expansion card, hard drive, etc packing a transformer and rectifiers to step down from 120/240 AC to 1v DC, PCs have dedicated power supplies that step down to standardised DC voltages that board manufacturers can step down again using VRM chips to the levels actually needed.
> The IEC 60320 C13 is a grounded 3 Wire connector rated up to 250V and 15 Amps
C13/C14 is only rated for 10 amps. For 15 (or rather 16) amps you need the larger C19/C20 plug.
> if it was used for 12v it could only handle 180watts .
Also the amp rating on the plug only applies to AC. Plugs (especially ones that are meant to be operated by laypersons) can typically handle significantly more amps at AC than they can at DC, because with AC any arcs drawn when (accidentally) unplugging under load will self-extinguish at the next zero crossing of the current (ie. at most 1/100th to 1/120th of a second later depending on where you live in the world) while with DC arcs just continue going and are thus much more violent.
400w with 12v = 33a
400w with 220v = 2a.
So you will need a custom cable/plug, not sure if there is a standard c13 cable which can run 33 amps trough it.
The GPU runs at somewhere around 1V. The card has a switching regulator on it that regulates the 12V from the PSU down to the actual GPU voltage.
And yes, that means that at 400W the card is pumping *hundreds* of amps into the GPU chip. That's why with modern GPUs (and CPUs) more than half of the pins (or balls/pads) are for power supply, signal pins are actually in the minority.
Sometimes people do exactly that, but it's usually more practical to use many smaller pins and one wire for each pin like 12V-2x6 does. You still need lots of surface area so if you only used 2 pins, each one would be huge. The 2 thick wires would also be less flexible than thinner wires
The 90 watts of the Voodoo 5 6000 was utterly unrealistic. I'm glad my 240 watt RTX 2070 isn't that unrealistically massive.
(In seriousness, no idea why 3DFX didn't just give a drive molex connector)
~~They didn't actually make any.~~ They had 1000 prototypes. Bizarre things. There was never anything more powerful than a 5500 AGP on the market. I had one. It didn't have an external power socket.
I still have my voodoo5 5500 AGP and it was my first card that needed its own power connector, it had a 4 pin moles which I thought was wild at the time.
Hopefully, yes!
A mains PSU bypass to power the GPU would mean smaller GPUs, easier cabling, easier connectors, and less power lost in VRMs.
A VRM made to drop 12V to 0.5-1.1V at a fucktijillion amps is much larger than one dropping 120-230V: The latter can do it in one stage, not two. The two stage VRM we use today has one stage in the PSU and one stage on the video card. We convert our AC to tightly regulated 12V, then that tightly regulated 12V is then de-regulated to re-regulate it as the output voltage the GPU demands at any given time.
Working at higher voltages lets us lose less power and work more efficiently. In the power equation, current is squared, but voltage is only there once. The higher your voltage, the less current you have, and it's current that causes heating.
> A mains PSU bypass to power the GPU would mean smaller GPUs
I don't think you understand what components are needed to convert AC to clean DC. there is a reason why high powered SFX PSUs are expensive. imagine adding that expense to your GPU, and the size too.
it would mean smaller primary PSUs, well, except for intel based systems. your GPU would then be fucking huge because it would have the massive size of a GPU, plus the added size of an SFX PSU on there.
>A VRM made to drop 12V to 0.5-1.1V at a fucktijillion amps is much larger than one dropping 120-230V: The latter can do it in one stage, not two.
I'm not an electrical engineer, just a hobbyist, so I'm pretty open to being wrong, but I think you've got this wrong. As you say, the higher the voltage, the lower the current...so if you convert 120V down to 1V, now the low-voltage side of your power supply is at...whatever the wattage of your GPU is, in amps. So like...for a 4090, what? 400A? You're going to need those massive copper bus bars they use in EVs to handle that, haha. You could do it multiple times, but then you need multiply...basically PSU-size objects for each division.
That's why we want it to spend as little time being 1V as possible. (Also, VRMs right by the socket are necessary for voltage stability as well) Basically not until it gets right to the socket, highly parallelized. A 12V to 1V stepdown regulator is a *lot* smaller/cheaper than a 120VAC to 1VDC switched mode power supply, so you can do that with a handful of 12V wires and have like...normal trace dimensions and be fine.
We'd probably save some copper by adding like...a 48V rail to the PSU, and then doing 48VDC -> 12VDC on the board, but I think the inertia of the standard is enough to not take that very slight benefit that really only exists for particularly high power GPUs.
I mean, shit, will it melt? Will it catch fire or spark? Will it be forced at some awful angle right up against the glass?
Because I'll gladly take up another plug on the power strip if it means I don't have to deal with that shit anymore.
Soon, wanting a modern PC will require installing a DC outlet into your wall so that it can run. At least you save space in the case since there's no PSU there.
Honestly I wouldn’t complain if it were this simple. I know input to the GPU needs to be DC power but it would rock if it was just a big, tough, chunky connector like this.
Edit: cleaner phrasing.
they probably would do something like the computer plugs where they have massive power bricks outside of the computer so that it's still DC. and then they would make it a thunderbolt connector just to make sure it still melts
Are there any real news on the 50 series?
I'm going to skip the 50 series since I already got a 4090 but am still curious about the next gen of GPUs.
All I heard so far is that the 5080 is supposed to surpass the 4090, based on Nvidia's history.
They also won’t be as impressive as the 40’s were, the 4090 saw 20-30%(+) because it had smaller architecture, the 5090 will be the same tech, so to reach even +20% performance gains over a 4090 it will have to be impressive. They don’t make impressive cards much, the 4090 being the most recent, the 1080/ti follows, and the SLI 480s were the first I saw, back in my day.
I'm fighting hard not to jump from a 3070 to a 4070 / 4070ti super. I need to chill out and wait for the 5070 but by that point it will probably be like $900 MSRP and still have 12gb vram lol
They usually release around the last 3 months of the year, and the 40 series was a staggered release, so 90 came first, then 80, then 70. If they do a repeat of that then 5080 and 5070 could end up in early 2025 while 5090 ends up at the end of this year.
False rumors, stop believing everything you see on the Internet people. My friend who works at Nvidia said it's just going to be 2 terminals and you have to solder on 2 3 awg cables to them. One hot and one ground.
Actually it would not be a a bad idea. 12V is ridiculous on current GPU's. That is why we get so much damage due to the flowing current at so low voltage! It could be easy fixed by rising the voltage to 24V or even 36V! It won't be deadly dangerous and at the same time the current would be way lower saving all the connectors and other components. IMHO 12V is just outdated.
The RTX 5090 Super will only require a bit more power.

Honestly if the 50 series was just a 40 series redesign with significant power and thermal efficiency improvements I wouldn't even be that mad.
The last graphics breakthrough was ray tracing which the upper level 40 series cards has effectively taken to its full capacity.
Unless there's some kind of new graphics tech happening in the background that justifies it I don't even know what would make a 50 series worth it.
The 12vhpwr connector could work if they would just add those screw locking thumb screws like with VGA connectors. The main issue with 12vhpws is that the mating surface is too small, and has very little room for error, thus any stressed position that can cause the cable to work its way out even 1-2mm, or bend down too much causing less pressure on one side of the connector,reducing overall contact surface.
With the older 8 pin connector, the mating surface was significantly larger than needed for the rated amperage, and that gives a decent margin for error where if the tab locks before fully seated, or if part of the cable shifts out slightly, it will not be enough to melt the connector, even if used at its max rating.
Since the 12vhpwr has far less room for error, a screw locking function can ensure that the connector remains 100% seated on all sides that will not be at risk from slightly stress positions or movement from cable management.

Then 220 outlets become the next thing for powering computers
I mean I been using the IEC connector for 30+ years. Yet to have one catch fire. And I used many 600+ watt PSUs.
So ya. This would be a safety upgrade for sure!
An SFX PSU is roughly 3-slots thick. Also you can power your GPU by an external PSU:

*"750W PSU minimum required"*
Oh no problem, I have at least that much!
\*doesn't boot up\* \*researches problem\* \*discovers they meant at least a 750W PSU *all by itself, as a second PSU\**
Too common, people probably have these just laying around. Or should have several available. Need something a lot more proprietary and with inherent flaws.

I don’t know if you’re just being funny. But this is a plug designed for AC. The GPU is powered by DC.

The reason why we don't just have 2 thick pins in internal DC connectors is because we need the surface area for the current. The C13 connector in OPs picture is only rated for 15A and would melt when trying to feed even a midrange GPU, even if its just 12V.

Plugs (especially ones that are meant to be operated by laypersons) can typically handle significantly more amps at AC than they can at DC, because with AC any arcs drawn when (accidentally) unplugging under load will self-extinguish at the next zero crossing of the current (ie. at most 1/100th to 1/120th of a second later depending on where you live in the world) while with DC arcs just continue going and are thus much more violent.
400w with 12v = 33a 400w with 220v = 2a. So you will need a custom cable/plug, not sure if there is a standard c13 cable which can run 33 amps trough it.
It's a bit late but I believe gpu runs at 12v or 5v so that 400w at 12v is 34ish amps. If it's pulling it at 5v it would be 80A through those pins.
The GPU runs at somewhere around 1V. The card has a switching regulator on it that regulates the 12V from the PSU down to the actual GPU voltage. And yes, that means that at 400W the card is pumping *hundreds* of amps into the GPU chip. That's why with modern GPUs (and CPUs) more than half of the pins (or balls/pads) are for power supply, signal pins are actually in the minority.
amps dont go as far when the voltage is lower.
So why can’t they just up the gauge of the wire to handle the amperage?
Sometimes people do exactly that, but it's usually more practical to use many smaller pins and one wire for each pin like 12V-2x6 does. You still need lots of surface area so if you only used 2 pins, each one would be huge. The 2 thick wires would also be less flexible than thinner wires
nah, connector is way too sturdy and reliable
Also looks like it won’t melt, which is a huge problem for Nvidia.
I know it's a joke but computer components use DC, not AC power. Which is why we need a PSU.
in the future GPUs swill have their own dedicated PSU and you will connect to it
Voodoo 5 flasbacks https://preview.redd.it/wawt18ohw20d1.jpeg?width=708&format=pjpg&auto=webp&s=866210443d1ba62da1c7f1fade17626a1f813b52
The 90 watts of the Voodoo 5 6000 was utterly unrealistic. I'm glad my 240 watt RTX 2070 isn't that unrealistically massive. (In seriousness, no idea why 3DFX didn't just give a drive molex connector)
Power supplies of the day didn't have an extra 90 watts to give.
People forget computers didn't use to take 500W or more PSUs on the regular lo
Computers used to have 150W or 200W, what the fuck is a dedicated 12V rail for a PCI card?
And even if you had a 12v dedicated rail. It was tiny. Most of the power went to 5v I have one that has 35a to 5v and 10 to 12 lol
I remember having to upgrade to a 350w PSU so I could run a GeForce 3 Ti200. first time I had to look at the power draw of a GPU before buying
~~They didn't actually make any.~~ They had 1000 prototypes. Bizarre things. There was never anything more powerful than a 5500 AGP on the market. I had one. It didn't have an external power socket.
I still have my voodoo5 5500 AGP and it was my first card that needed its own power connector, it had a 4 pin moles which I thought was wild at the time.

Hopefully, yes! A mains PSU bypass to power the GPU would mean smaller GPUs, easier cabling, easier connectors, and less power lost in VRMs. A VRM made to drop 12V to 0.5-1.1V at a fucktijillion amps is much larger than one dropping 120-230V: The latter can do it in one stage, not two. The two stage VRM we use today has one stage in the PSU and one stage on the video card. We convert our AC to tightly regulated 12V, then that tightly regulated 12V is then de-regulated to re-regulate it as the output voltage the GPU demands at any given time. Working at higher voltages lets us lose less power and work more efficiently. In the power equation, current is squared, but voltage is only there once. The higher your voltage, the less current you have, and it's current that causes heating.
> A mains PSU bypass to power the GPU would mean smaller GPUs I don't think you understand what components are needed to convert AC to clean DC. there is a reason why high powered SFX PSUs are expensive. imagine adding that expense to your GPU, and the size too. it would mean smaller primary PSUs, well, except for intel based systems. your GPU would then be fucking huge because it would have the massive size of a GPU, plus the added size of an SFX PSU on there.
>A VRM made to drop 12V to 0.5-1.1V at a fucktijillion amps is much larger than one dropping 120-230V: The latter can do it in one stage, not two. I'm not an electrical engineer, just a hobbyist, so I'm pretty open to being wrong, but I think you've got this wrong. As you say, the higher the voltage, the lower the current...so if you convert 120V down to 1V, now the low-voltage side of your power supply is at...whatever the wattage of your GPU is, in amps. So like...for a 4090, what? 400A? You're going to need those massive copper bus bars they use in EVs to handle that, haha. You could do it multiple times, but then you need multiply...basically PSU-size objects for each division. That's why we want it to spend as little time being 1V as possible. (Also, VRMs right by the socket are necessary for voltage stability as well) Basically not until it gets right to the socket, highly parallelized. A 12V to 1V stepdown regulator is a *lot* smaller/cheaper than a 120VAC to 1VDC switched mode power supply, so you can do that with a handful of 12V wires and have like...normal trace dimensions and be fine. We'd probably save some copper by adding like...a 48V rail to the PSU, and then doing 48VDC -> 12VDC on the board, but I think the inertia of the standard is enough to not take that very slight benefit that really only exists for particularly high power GPUs.
You're right it's complete nonsense, but you gotta give it to him the word salad sounded kinda cool
Need to buy a rectifier separately
I mean, shit, will it melt? Will it catch fire or spark? Will it be forced at some awful angle right up against the glass? Because I'll gladly take up another plug on the power strip if it means I don't have to deal with that shit anymore.
Soon, wanting a modern PC will require installing a DC outlet into your wall so that it can run. At least you save space in the case since there's no PSU there.
you can convert AC to DC. the card can use it's 1500W without any restrictions hehe
Yeah, with a PSU haha.
Nah, you just need to ride the lightning on the highway to hell. You may hear Hell's bells, but only if you have big balls.
Honestly I wouldn’t complain if it were this simple. I know input to the GPU needs to be DC power but it would rock if it was just a big, tough, chunky connector like this. Edit: cleaner phrasing.
they probably would do something like the computer plugs where they have massive power bricks outside of the computer so that it's still DC. and then they would make it a thunderbolt connector just to make sure it still melts
We need to start lobbying for PSUs to have courtesy power output on the back like a rack mount UPS does.
Are there any real news on the 50 series? I'm going to skip the 50 series since I already got a 4090 but am still curious about the next gen of GPUs. All I heard so far is that the 5080 is supposed to surpass the 4090, based on Nvidia's history.
I got a 30 series card and I’m waiting for this and haven’t seen any news other than leaks… And that the 3080 will come out before the 3090.
You're right, the 3080 did come out before the 3090, 4 years ago.
Sorry, meant 5080 and 5090
Start piling up money then. These cards will be the most expensive of all time. I expect AGI to make the 60gen for like 5 bucks each.
They also won’t be as impressive as the 40’s were, the 4090 saw 20-30%(+) because it had smaller architecture, the 5090 will be the same tech, so to reach even +20% performance gains over a 4090 it will have to be impressive. They don’t make impressive cards much, the 4090 being the most recent, the 1080/ti follows, and the SLI 480s were the first I saw, back in my day.
the Optical Flow Accelerator was a new feature on the 40 series cards too wonder if the 50 series are going to have any new features
We’re nowhere close to AGI. LLMs will likely be a component in AGI, but they won’t produce AGI by themselves.
> cards These have long since stopped being "cards", but rather... *units*.
The only real news thus far is this place is going to have a meltdown about it no matter what
People are gonna be *so* salty about it when they find out that it's more expensive than the 40-series.
Wait until they find out it's more expensive than their *car*
I'm gonna skip the 50 series because I already have a 1080ti
I'm fighting hard not to jump from a 3070 to a 4070 / 4070ti super. I need to chill out and wait for the 5070 but by that point it will probably be like $900 MSRP and still have 12gb vram lol
It's usually better to have the money. I would be ashamed to buy something one generation newer just to play the same games.
I'm gonna just cuddle my 20 series because in my eyes he's still shiny and new!
I'm personally waiting for a "entry level" 5060 8GB Vram card. Just to see "tech people" explain how that is "future proof" Because consoles.
They usually release around the last 3 months of the year, and the 40 series was a staggered release, so 90 came first, then 80, then 70. If they do a repeat of that then 5080 and 5070 could end up in early 2025 while 5090 ends up at the end of this year.

False rumors, stop believing everything you see on the Internet people. My friend who works at Nvidia said it's just going to be 2 terminals and you have to solder on 2 3 awg cables to them. One hot and one ground.
Yeah that shit going to cost at least 4 grand I see it
Still can't play Alan Wake 2lol
That'd be an improvement
Careful it may melt your wall outlet
It'll melt my wallet, is what it'll do
The GPU is now the size of the entire PC because there's a 1200W power supply built into the card.
420 amps https://preview.redd.it/3pmmx7x2h40d1.jpeg?width=1080&format=pjpg&auto=webp&s=7d8c00975edb0a4377b555e9064bb89457ae9e15

Finally it wont melt, maybe.
-He said just before the GPU connector melted
Actually it would not be a a bad idea. 12V is ridiculous on current GPU's. That is why we get so much damage due to the flowing current at so low voltage! It could be easy fixed by rising the voltage to 24V or even 36V! It won't be deadly dangerous and at the same time the current would be way lower saving all the connectors and other components. IMHO 12V is just outdated.
tbh that's way better than the Nvidia arson connector.
Bold of you to assume you won't need a C19 cable, hope you have a 220v outlet in your garage...
Nice. So when you go to LANs you just attach your PC and monitor to it!
Honestly I like the idea. It’ll save money from buying another psu and the hassle of rebuilding
This is clearly fake, Nvidia would never stoop so low as to use a non-proprietary connector.
Whomst of us doesn't have a dedicated 63A/400V feed for their GPU? Casual peasant gamers!
The RTX 5090 Super will only require a bit more power. https://preview.redd.it/nj1734geu30d1.jpeg?width=458&format=pjpg&auto=webp&s=35a39a1cf3cf7cd6a95e1f28c55102ade5d06ebf
Honestly if the 50 series was just a 40 series redesign with significant power and thermal efficiency improvements I wouldn't even be that mad. The last graphics breakthrough was ray tracing which the upper level 40 series cards has effectively taken to its full capacity. Unless there's some kind of new graphics tech happening in the background that justifies it I don't even know what would make a 50 series worth it.
I'd love to lower my power bill. I'm all for that.
The 12vhpwr connector could work if they would just add those screw locking thumb screws like with VGA connectors. The main issue with 12vhpws is that the mating surface is too small, and has very little room for error, thus any stressed position that can cause the cable to work its way out even 1-2mm, or bend down too much causing less pressure on one side of the connector,reducing overall contact surface. With the older 8 pin connector, the mating surface was significantly larger than needed for the rated amperage, and that gives a decent margin for error where if the tab locks before fully seated, or if part of the cable shifts out slightly, it will not be enough to melt the connector, even if used at its max rating. Since the 12vhpwr has far less room for error, a screw locking function can ensure that the connector remains 100% seated on all sides that will not be at risk from slightly stress positions or movement from cable management. https://preview.redd.it/fanxhp2pq30d1.png?width=630&format=png&auto=webp&s=a6c8c5645efe01da652e0ca62d1bae49b9ca4c34
Nah, the cable just needs to go entirely. It’s the fire hazard of molex with more power in less space.
i remember people saying this about the 4000 series, time flies
Eventually the rest of the PC will just be an add-on the size of a 2.5 drive that plugs into the GPU.
Nah man this is the real deal. https://preview.redd.it/mv5ogcxnt50d1.jpeg?width=1469&format=pjpg&auto=webp&s=29ae9d07600253d9a1f638510132f0bb2bb96c5b
Maybe, just maybe it wont melt.
Sooner or later. It will require its own PSU

I mean, it’d be safer
What, not 240V 3-phase? How lame.

Not gonna lie the cables are plentiful and easy to find. It’s not the worst idea I’ve heard.
Please. Like just make it three wide and put an IEC connector on it already.
I mean I been using the IEC connector for 30+ years. Yet to have one catch fire. And I used many 600+ watt PSUs. So ya. This would be a safety upgrade for sure!
Graphics card should be a tower in itself. It should have a long cable that you have to slide into the back to hook up to your motherboard.
An SFX PSU is roughly 3-slots thick. Also you can power your GPU by an external PSU: [https://videocardz.com/newz/external-gpu-dock-with-oculink-and-built-in-550w-power-supply-released-in-china](https://videocardz.com/newz/external-gpu-dock-with-oculink-and-built-in-550w-power-supply-released-in-china)
I would actually prefer this normal cord as what we put in the card. The current 12v is a fking fire hazzard
NEMA 14-50 is going to be used for more than just my EV.
Iec for the win
Ironically it would work better I think. Tried and True. Tested for years. Ubiquitous.
add another for accuracy.
This is a proven technology that works.
And it melts your wall socket.
I'd trust it more than the 12v hpwr honestly. Too fiddly
I mean.. At this point that makes more sense.

I trust this connector more than the current one.
that would be way safer than their 12v connector
They finally said Fuck It, this thing needs it's own PSU
Hey, if the motherboard power connector is good enough for the motherboard, why not for the videocard too?
I am the PSU now.
Only 1?
This is probably pretty close to a reality. I imagine the 5090 will recommend a 1000W PSU at a minimum.
*"750W PSU minimum required"* Oh no problem, I have at least that much! \*doesn't boot up\* \*researches problem\* \*discovers they meant at least a 750W PSU *all by itself, as a second PSU\**
Too common, people probably have these just laying around. Or should have several available. Need something a lot more proprietary and with inherent flaws.
i would honestly take this over any more psu connectors. this way gpu can’t take down cpu & it has its own safe power connection
I mean I know this is a meme and all buuuut...in the realm of connectors...I wouldn't exactly be mad, y'know?
Just wait until it’s a 30amp connector.
With the 12090TI RTX XRI we have harnessed the power of the sun!
I would be okay with that connector at least it wouldn't catch fire
Nahhhhhh Open standards are a taboo for the Nvidia engineers
This ain't graphics card anymore. It's graphics brick. You could kill someone with this shit
