Doing that does nothing - in case of bad contact, reseating the connector (unplug/replug) is the only way to change the contact.

Only a clamp and measure or built-in per pin measurement can confirm even power distribution.

The design is broken. If everything works as expected 900w+ seems okay for at least short term.

But mine burned at 550w while checking cable for every 3 day by pushing forward to socket

I have seen a lot msi yellow one maybe that one has defect or something like that dunno

I agree, I think there's something not quite right with those MSI adapters with the yellow plug. I'm still a little baffled what is different that causes all six +12v pins to overheat though.

Made a couple runs last night. To get much farther i gotta go cold. There's only so much you can do when your GPU is running well over 1000w.

You'd likely score higher on 576.28 too. Probably handicapping yourself on 576.52 in PR. 576.40 was quite a bit slower when I tested it anyway.

Guys need help

i have been running my 4090 with a Be Quiet Dark Power 13 1000w , i have been using it with the included 12VHPWR cable, im running a 14900ks (undervolted a bit).

Now with the 5090 i would like to upgrade the cable , wich one do you guys recommend me? Or should i upgrade my PSU?

thanks in advance.

I would tend to think the cable wasn't plugged in all the way, but who knows. Remember that only part of the current returns through the ground side of the cable (around 50% in my case, the rest through the pcie connector and motherboard), so it's not surprising that the ground side doesn't overheat like the +12V side.

I feel pretty confident that my 5090FE will never burn/melt the cable, other people feel this way too right lol?? Now that I trust it, I do not check it. I do not worry about it anymore. I have temp sensors on it, it’s only ever been plugged the one time since installing.

It is strange yours burned at 550W, i'm using it daily at 600W for 3month without any problem.
But i'm getting the Astral, and i monitored the pin so i'm sure it was well cabled.
I had little issue with default premium Corsair cables (AX1600i) which doesn't have nice spread load balancing. (pin 1 and 2 was more than 10W lower than others.
Then i buyed the same cables as domdtx (cable mod) for Corsair, now after playing with port selection on PSU side, all is well load balanced, i have just a diff of 3W on PIN1.
So the cable is very important, and if you want to be sure your card will not fry, you need to buy astral or the new loadbalancer monitored power from TG.

You’re pulling ‘well over 1000w’ in PR? Are you sure?
Click to expand...
Im absolutely sure. Tbh 1000w is likely understating the actual power draw. On my Kill a watt meter my entire system is was seeing between 1300 and 1700w while running port royal and upwards of 1850w running steel nomad. My PC with pumps and fans idles at about 270w. And since its running an AMD CPU its probably around 400w absolute max under these kinds of loads. So the GPU is likely pulling 1200w+ but hard to say for certain

Got it. What gpu voltage is it maxing out at? Those numbers would be dramatic outliers to some of the other folks that have shunted in here. SN at about 950w seems to be the max, I think I’ve pulled slightly more in the game ‘The Ascent’ at 4K max settings, and that’s tested directly with a wireview

Now that its no longer power limited it seems to automatically run about 1.145-1.15V. I dont have any sort of voltage control just yet. The only thing ive done is bypass the power limit. Heres a picture on steel nomad of the highest power draw i saw. But i dont think that value is actually 100% accurate.

My killawatt meter constantly kept beeping at me throughout almost the entire run because the total system power basically stayed above 1600w. Highest i saw on the Killawatt was ~1850w.

Just got my 5090 FE installed.

Coming from a 4090 FE, been using both Cablemod 90 degree adapter (both V1 and V2) and after the recall i used Cablemod 90 degree cable on it.
Took it off today, looks as good as new, so over two years with both Cablemod adapter and 90 degree cable without any issues. They have also been taken on and off a few times, just for the record.

For the 5090 I decided to use the included NVIDIA dongle for now, just to be safe. I also have an old (no stealth sense) straight Cablemod 12vhpwr cable that i used on my 3090 FE, but i'm a bit hesitant to use it on the 5090.

So, anyone using 4x8pin to 12vhpwr custom cables on their 5090's? I have an older EVGA 1600W so i have only the 4x8pin option.

I saw an statement from ModDIY claiming their older 12vhpwr cables should not be used on 5090's, but on the other side, is it not only the connector on the GPU side that have changed?

I can ofc continue to use the NVIDIA dongle, but its so much cleaner and easier to do cable managment without that ugly dongle.

Sounds like ModDIY upgraded their cables. Doesn't really have anything to do with a spec change. The only spec change I've seen on the cable side is that the clip is slightly shorter to hold the plug tighter. My advice is to get a good dedicated cable (4x8 pin is 100% fine). If you are very concerned about melting, buy a cable with separate wires (that uses cable combs) and use a cheap clamp meter to verify the plug has good balance.

Can I use the existing 12VHPWR cable with the new RTX50 GPU? | MODDIY | Help Center

I'm using Cablemod 8-pin cables now, and then the nvidia dongle. 2 of the 8pin cables have combs, the other two do not as they have two of the pins "lose" (can make it a 6pin on the pcie side), but they are all seperate, no daisy chained, using 4x8pin ports on the psu.

Maybe i just leave it like this and call it a day :)

What voltage did it read in desktop when you lock V/F to an arbitrary point like 1.2v? ( at 0% and 100% voltage slider )
