NVIDIA RTX 50 SERIES - Technical/General Discussion

I've sold a few GPU on the bay now and touch wood never had an issue .... i am past the 30 day period now as well so its a done deal . for what its worth it seems i let it go cheap as they are selling for £2000 now which to me is insane considering they never cost anything like that new , were £1700 brand new at release :cry:

You didn't let it go cheap, you let it go for a reasonable amount with a much lower risk of return or scam. I'm not losing any sleep over having sold my 4090 Strix for £1650 back in late November.

Got one too. God bless https://notify-fe.plen.io/

I read about the drop in the US yesterday... I thought another one had to be around the corner!

Lucky you. My discord notification never went off and I cannot leave that site open on my work laptop. Maybe it's a blessing in disguise with all the black screen and melting issues.

So what's the fastest Nvidia GPU that *won't* burn your house down? 5080? 3090ti?

lol maybe one of those…

IMO buying a new cable (regardless of the ‘spec’) is probably a good way of making sure the risks are as low as possible. Corsair / Seasonic aren’t going to be putting out dodgy brand new cables these days.

Therefore you should be good regardless if:
- you have a H++ PSU (best option);
- if you have a H+ PSU, you nevertheless get a new cable, reliable brand (H++ so you know it’s not from ‘old stock’) that is compatible with your PSU - same manufacturer;
- you take care installing it.

Well you can power limit a 5090 to get better performance than a 4090 FE while having similar power demands.
 
All this nonsense and arguing about old cables, new cables, 12VHPWR, 12V-2×6, H+, H++ was pickling my brain so I just went and swapped my 2yr old Corsair 2x8 to 12VHPWR cable for the adaptor Nvidia included in the box and fed it 4 8-pins from 4 separate outputs on the PSU.

At least now if anything happens I can point to the adaptor and be like, this is what you gave me to use :p

Also did some science™ and put the card on loop in 3Dmark Steel Nomad and after about 20mins of it pulling 575w I did some cable checks. None of them felt warm to the touch. I don't have a fancy thermal imaging camera or current clamps but I do have a laser thermometer so used that to take some readings and nothing looked particularly hot on either end of the cables or along the length of them.

Are you using an "older" psu without the 12V-2×6? I have a really nice ASUS Thor P2 1200W which is apparently ATX2.0 and I don't really want to change that just for a slight connector change.

If I got another 5080 I think it would have to be an FE (so I could route the cable without any bend) and I'd use a multi 8pin into 12V-2x6 cable from the PSU.

I upgraded to a 2024 Corsair RM850x for the single cable (12V-2x6) solution and honestly I think now it was a waste of money.

I'll just be using the Corsair 2x8pin if and when I get one. I don't have enough included cables to do 1 to 1 in the adapter, so it is what it is. The PSU is highly rated, and so if either side kicked up a fuss I don't think they have much to stand on.

I've got a PSU with PCIe 5.1 sockets and OEM 12Vx6 cable, but I will use the 4x8pin cable that comes with the GPU. I use a shroud over the PSU and the GPU is vertically mounted pretty much in front of it, nobody will ever see those cables. 150C degrees at the PSU socket is insane!

Nvidia should fire the elecricians who came up with this solution, and redesign the socket/plug.

I get the impression the engineers who designed it are not the ones at fault here. They have been told the card has to look a certain way and fit within a certain package. In this case, I imagine they were told they have to use this stupid cable and connector.

The one thing I don't understand is why the power isn't balanced across the available cables.

Ah, hold on, does that have the 2 cables on the PSU side and one cable on the GPU side??

If so, there is no native H+ connector on that PSU… in which case you should be able to connect that to a H++ GPU female connector and be OK.

I think, anyway.

This is based on risks increasing by having a H+ female connector on the PSU and/or GPU. If you don’t have this socket on your PSU, then there is nothing to solve.

Yeah it does have a native 12V-2x6 port and supplied 12VHPWR cable (marked with H++). But my current stance is that it's best to use a multi 8-pin to 12V-2x6 cable (purchased separately from Corsair) to spread the load (at least at the PSU end)

That sounds promising. I don't have the 12vhpwr connector or any of my psu's they have what they look like two mini pci-e power connectors to one 12vhpwr connector. Asus Thor and rmx shift x the older one not the new 2024 version.
