SharpeXB Posted February 15 Posted February 15 TL;DW all these videos. How many 12V-2x6 connectors have actually failed? Or is this just theoretical? The 12VHPWR have definitely melted. Apparently some of the newer 4090s are made to accept the 12V-2x6 but you probably have to remove the cooler plate to find out. https://www.tomshardware.com/pc-components/gpus/not-all-rtx-40-series-super-gpus-use-the-new-12v-2x6-connector-new-images-of-16-pin-h-power-connector-emerge i9-14900KS | ASUS ROG MAXIMUS Z790 HERO | 64GB DDR5 5600MHz | iCUE H150i Liquid CPU Cooler | ASUS TUF GeForce RTX 4090 OC | Windows 11 Home | 2TB Samsung 980 PRO NVMe | Corsair RM1000x | LG 48GQ900-B 4K OLED Monitor | CH Fighterstick | Ch Pro Throttle | CH Pro Pedals | TrackIR 5
Aapje Posted February 15 Posted February 15 All the 50-series cards presumably use the 12V-2x6 connectors, so all those that melted count.

TZeer Posted February 15 Author Posted February 15 Doesn't matter what cable they use. The problem is that there is no monitoring or any system in place to let you know if one wire starts to draw more current than the others. I think there are a few partner cards that have possibility to monitor if there is uneven distribution, but that's it. From the info and reports that have come so far it seems that it's so small safety margins that even doing everything correct will not guarantee you not getting hit by the problems. This was demonstrated by a guy where he plugged in the card 2 times with the same equipment, one where everything was within spec, and one where the the current in the wires where out of spec. Nothing physically changed in the setup. And with the small amount of 5090 cards that have even hit the market it's worrisome.

I would not rely on a "smart" software solution when it's safety relevant. This is a safety issue and the graohic cards has to avoid this by appropriate hardware and layout design. This is just a weak and dangerous product design and not ready for market.

TZeer Posted February 16 Author Posted February 16 The insane part here as well is the premium they are charging for it... 1
SharpeXB Posted February 16 Posted February 16 (edited) It doesn’t look like there are too many easy solutions here. How about a power brick for your GPU? https://medium.com/@noahbean3396/the-rtx-5090-power-connector-controversy-another-generation-another-meltdown-c9863b93b64d No wonder it’s such a small improvement over the prior generation. It looks like it’s at the limit of what the current power ecosystem can handle.

The connector are interchangeable, but they already started replacing 12vhpwr connectors with 12V-2x6 connectors for the 40-series cards, so presumably they have now transitioned over fully. However, this merely reduces the risks a bit, it is not a full fix. 1
