On NVIDIA graphics cards, the 12V-2x6 16-pin power supply interface is already standard, but AMD has never officially accepted it. Only the non-public versions of ASRock and Sapphire can occasionally be seen (ASUS used it on the R9700 professional card), but I didn't expect that something happened!The first is ASRock's RX 9070 XT Taichi Taichi Edition. In August this year, the first case of interface burnout occurred. It can be clearly seen that two pins have been burned.
Some other netizens questioned that because three 8-pin adapter cables are used, the power supply may not be very good.
The user responded,Its 850W power supply is indeed not very good, but the power supply is absolutely no problem. Under normal circumstances, the power consumption of RX 9070 XT is only 300-340W., so as not to cause insufficient power supply, he felt that replacing it with a better power supply would also cause burnout.
Next is Sapphire's RX 9070 XT NITRO+ nitrogen driver. The 16-pin interface is hidden under the back panel, which looks more beautiful, but it is also burned.
In the photos given by netizens, you can see that up to 5 pins are burned, andThe connector is specially made blue, to avoid incomplete insertion, will not help.
This netizen also used an adapter cable, but the power supply wasCorsair’s RM1000X 1000W, we can no longer blame the power supply.
It seems that after the upgrade from 12VHPWR to 12V-2x6, this power interface still needs to be improved, including more uniform current distribution, adding an overheating detection mechanism, etc.
