NVIDIA RTX 50 SERIES - Technical/General Discussion

Doesn't using 4x8pin into the adapters just push all the problems into the adapter, how does it stop the plug into the gpu from melting? I know nothing about how this stuff works.
 
Not that it fixes the issue at all; but I will be undervolting to around 450W and overclocking back up to around stock levels.

Sounds like a sensible mitigation but I suppose that might not help if due to a connection failure all of the current is being shunted down a single wire as per the Der8auer vid…? Edit: I know you said it doesn’t fix the issue, but was wondering if there is anything else you could have meant.

Is there any indication of a better 5080 stock situation in the next month or two? Id actually buy one at or close to msrp but there's absolutely nothing, surely people aren't actually buying them en masse at the current ludicrous pricing. I've a 7900xtx on order because of it ‍♂️
I don't even think demand is especially high its just that the ridiculously low stock levels are panicking people into paying way over the odds.
 
All this talk of connectors melting etc and people are still waiting to buy them after seeing the FE stock alert on here. Madness

Avoided the 4090's for same reason here and avoiding the 5090s too now, while Nvidia keeps using these connectors I will avoid a fire risk no matter how many times they will state they fixed them. I knew when they last said they fixed the issues on the 4090s that it didn't and we still saw melting connectors then too and here we are again.

This is the most insane thing I have seen from any company in many years, this is not just a design fault that damages their product (planned obsolescence maybe), but can also kill their customers or burn their homes down.

3 x 8 Pin has been proven to work and even cards with 4 x 8 Pin... there was zero need for this new connector and once it showed issues it should have been recalled and changed to something totally new or back to the previous design that has been proven to work well and is safe.

Maybe we should thank Nvidia for saving us the money.. and killing all that FOMO people were having. Anyways ... The whole PC market is self destructing as we see with the silly prices and the never ending greed at each stage now. Honestly this maybe for the best with how things are going... Just look at the ASUS TAX now and so on... it has all become insane.

Isn't every PSU that comes with 12VHPWR connectors/ cables "third party"?

The fact that no one is concerned about all the random old PCIE 8-pin cables that get plugged into the supplied adapters speaks volumes about how crap the design of the 12VHPWR connector is.

12VHPWR cables must be anointed by Nvidia as worthy but the PCIE 8pin cables that we are supposed to plug into the adapters? Those are fine. Plug in any PCIE 8 pin cable from virtually any manufacturer and you're fine.

Buildzoid nailed it when he called the connector "12v high failure rate".
I dont think they are classing the cable that comes with a PSU to be third party, but further clarification would be nice,

It does mention Corsair PSU cable and seems to be ok with it, but dont quote me on that.

I know it's not the answer, but this is the path anyway, regardless of what's going on.

On my 5080 I'm currently testing a curve undervolt + overclock - getting a sustained 2950Mhz on the core at only 0.91v! (stock is 1.02v at ~2750Mhz!) This means it's only using ~270w in Cyberpunk with full path tracing and is performing significantly faster than stock whilst obvioulsy using less power and running even cooler.

Lots more testing to do but It seems completely stable so far. These 5080's seem incredible for OC'ing and now undervolting too....

for some of us this is noting new :cry: my 4090 melted its cable which while less than ideal was soon sorted by fitting another connector which remained perfect for the rest of its time.... obviously would rather it was sorted and imo the solution is to fit 2 of these connectors on the cards but as no one is doing that then just have to deal with the same **** we had with the 40 series unfortunately .
 
Looks like a new nvflash 5.867.0 works with series 5. I'll be throwing the 600w OC bios onto my Palit when it arrives. That 25w and 1% gain wouldve really bugged me :D
 
A few people on here that don’t own one have acknowledged it :p

I doubt Nvidia will, did they ever with the 40 series?

True! But these things tend to not turn out well…would be a shame to have to let it get dangerous!

Also doesn’t the 4090 have a lower tdp AFAIK? Wouldnt that make the 5090 more hazardous?
 
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.

Derbauer's video demonstrated the problem starts from PSU side because the current is inconsistent between each 12V wire 150C at PSU and 90C at GPU. Perhaps the the source split into 4 times more wires will help, plus the 8 pin socket are much more thicker, more contact area, more secure plug altogether. Possibly the GPU socket will still heat up, but maybe it won't be as bad.
 
Not true. The PSU could be designed to be able to sense the current in each of the six live wires, and to load balance them. It doesn't need to know what its connected to, just the total load request and power going down each live wire.
What does true or false have to do with what expectations?

If you're suggesting that the entire ATX specification should be changed simply because Nvidia can't design a connector then maybe you're being a bit unreasonable. Can it be done, sure if we put our minds to it most things can. Should it be done, heck no because expecting an entire industry to bend over backwards just to accommodate a single organisation is ridiculous.
