Yes and no.

It actually depends how the sense wires are configured on the connector. Forbthe Nvidia adaptor, yes 3 = 450w and 4 = 600w. But for anything aftermarket, not necessarily, there are 2 and 3 wire branded cables that allows 600w and the reasoning because the sense wires are configured to allow 600w.

That's supposed to be the big selling point of this ATX3.0 16 pin HWPR system; the manufacturer can configure any power limit they want directly by how they wire the 4 sense wires - this single connector supports physical power limits anywhere between 150w and 600w

True, thanks for going further in-depth.

I’ve got the Corsair 600W cable turning up in a couple of days.

Here’s hoping my RM1000X supports 600W rather than 450W.

Got my 4090FE running with 4 separate cables currently and it’s a bit of a mess TBH. The replacement Corsair cable should tidy things up nicely.

Did you get it from Corsair I have been waiting for them to come back into stock.

I believe you have to have a 1200w psu and above for the Corsair cable to supply 600w from 2 8 pin pcie.

3 days now with no new burnt adaptor or cables reported

Maybe it was just a bad batch from the manufacturer?

With all the TUFS melting I hope it was just a bad batch and not a bad batch of graphics cards that can damage the connectors. We will see, we did have a recent driver update too, could that of helped too ? Who knows ... Need Nvidia to get back to us all and if it turns out to be drivers like with capacitor gate aka POSCAP vs MLCC .. Turned out to be drivers pushing to hard on the cards.

I think you might be right but we shall see.

Had a 580W spike but typically the power usage is actually down on the 3090FE I used previously. Capped MW2 @ 120/4K native, no DLSS, and it was using on average <300W.

If the cable is no good I’ll just pop it on the MM and sell it on at cost. Corsair are sold out so had to use an easily found third-party instead but it was about the same price £20+PP.

It now 4 days on so no new burnt adapter or cables cases reported. 15 cases so far to date out of thousands who ordered 12VHPWR cables.

MODDIY & Other Cable Manufacturers Have Ran Out of NVIDIA 16-Pin Adapter Cable Stock Due To Huge Demand

MODDIY, CableMod, & other online retailers are struggling to keep up with the demand for 16-pin 12VHPWR cables for the NVIDIA RTX 4090 GPUs.

A reddit user warned everyone about danger of 180 degree adapters after he used 5 FormulaMod 180 degree adapters and 1 adapter melted on RTX 3090. Interesting, these adapters has same C style crimp connectors as Nvidia 12VHPWR adapter C style crimp connectors.

I read comments, user posted a link warned everyone not buy 180 degree adapters from AliExpress after his PC was destroyed 2 years ago when 1 adapter at the bottom was melted and burst into fire. The 4 adapters he bought all had same C style crimp connectors.

PSA: don't buy aliexpress PCI adapters.

So I have a little warning for all of you guys looking at these: I recently bought them for my rig, and I ran them on 2 RTX 2080 GPU's. They do look awesome, and they clean up the cables real nice. So I put my PC on standby and go to my parents in law for Christmas. About 2 hours later I get a ca...

why would you buy any electronics from ali express when it's checheapest of the cheap, usually made with no safety standards or fake ones printed on them

ATX 3.0 PSU now melting connectors too, again maybe not inserted correctly or is it an issue with the graphics cards or the silly connector standards.

i think the solution to this problem is to plug the adapter first before installing it on a motherboard.. that way you can have a good look if you have pushed it down enough

Well, well, well. Look at what we have here. This guy has a ATX 3.0 PSU and using a Gen5 cable for his Gen5 connectors and still melts the cable? This throws a pretty sizeable and harden wrench into the works that this was limited to a few adapters. This is starting to look like a major design fault. And blaming people for "not connecting them correctly" will simply be ignored when the design itself comes into question. Lets be honest with ourselves people are plugging them proper.

Personally, I wouldn't want to use the GPU until the issue is identified, verified and confirmed to be fix. Spending $1600+ is a lot of money to worry about melted connectors. Specially when I know, on my end, I've done everything correctly.

This guy also looks like an experienced system builder and has many graphics cards and systems and an enthusiast too.. so it is starting to make me wonder what is really going on as we have not seen even one FE with a melting issue... is it the cards for AIBS that are the problem and they didn't follow Nvidia's power advice on the reference models design that they give them... It all smells of more than one issue causing all this now to me or a combination of issues.

If only EVGA could speak freely on the situation. Because I am beginning to wonder if this has anything to do with EVGA's "last straw". Because it's eerie coincidental that they got out right when this turns up.
Just saying...

vapor matt · 4 Nov 2022 at 17:25

What this does is make the possible 4090ti have dual 12 pin connections as one just isn't enough for the power draw of an AIB 4090 safe. It wont be long before there is a fire and then we shall see the S*** hit the fan.
