Prototype NVIDIA GeForce RTX 5090 with Four 16-Pin Connectors Pictured

What if NVIDIA's GeForce RTX 5090 GPU had access to not one but four 16-pin power connectors? Not only would it draw much less power per connector, thus avoiding overheating of the connector in some cases, but the power coming into the GB202 could theoretically scale to 2,400 Watts. This is precisely what NVIDIA tested with its latest leaked GeForce RTX 5090 GPU engineering sample. Pictured below is a PCB that was destroyed after testing. Around the edges of the card, you can spot several USB headers, pin test points, and diagnostic connectors. These features are standard on development samples but are removed from retail models. On the I/O bracket, there are five display outputs, which are more than what you usually find on a gaming card. This suggests NVIDIA was testing output strength and signal quality under different loads. Since we can't see the back side of the board, it's unclear if the chip itself is from the GeForce RTX 5090 series or the RTX PRO 6000 Blackwell variant. However, it is most likely a super early sample of RTX 5090 before volume production began.

Maybe they scrapped it cause it had micro usb, not usb c connector? :P
But 4 points of failure if it was connected to 2.4 kW.
Ps thanks for article it's always fun to look at engineering samples :).
 
That's what this is for. They'll get there eventually.

Some engineer at Nvidia "I don't why they complain about connectors melting, everything looked fine when I tested it"
 
The safety margin is just too high they have to abandon it.

It would need 6, so no more than 100W can go through 1 pin if the other 5 fail.
 
Soooo...to summarize......

If this card ever sees the light of day, instead of watching just 1 connector melt & set fire to your rig and/or burn down your house, you will have the pleasure of watching it happen 4 times, or at 4x the intensity, hahahahahahahahahahaha..:roll:
 
I mean it might have balanced the power correctly if they fitted load balancing hardware but since they didn't bother doing it with a single HiFailRate socket I kinda doubt it. But I do wonder what they where testing and more interestingly is how would they have cooled it.
 
I could fix this card…..just saying!
 
4 x oldschool 8 pin connectors would actually make sense
 
At the prices these things are going I would expect them to be equipped with a fuel cell
 
So nvidia did not want to spend 5 usd on connectors to safeguard users, disgraceful.
 
And just like that a 3.2KW PSU sounds very reasonable..
 
Imagine a dual GPU video card with 5090 chips....

Engineering samples usually don't have any restrictions - a GPU can consume over 1500W on such cards and still don't break a sweat.

Those things usually chilled with sub ambient temps to really get a good overview of what the chip is capable of.

Called it elsewhere... if you want to run the 6090... better emigrate to Europe where a socket can go up to 3.5kw :D
