My PSU is an 850w EVGA supernova, it comes with 2x PCI power cables both are 8pin from the PSU and terminates as 8 pin (6+2) and 6 pin on each cable, the Graphics card I am looking at getting (RX 7800XT) needs 2x8pin, can I just connect 2 x PCI power cables to the PSU and use the 8pin (6+2) on each cable (leaving the 6 pin on both unused). Alternatively can I just get a new PSU cable that is 8pin from the PSU with 2 x 8pin on the other end to connect to the Graphics card?
It’s all on the 12v rail so it shouldn’t matter, should it?
yes you can use them with two different cables on the 12v rail. It’s not a problem. But be careful when buying cables for modular PSU online, just buy from the producer.
I have 2 cables that came with it (both have an 8pin and a 6pin on the GPU end so I’m just going to use both cables and just use the 8pin connector on each.
It’s been a while since I last build a PC. I should know this shit, I used to be a system builder… But that was also many years ago.
Thanks!
I feel you. I’d been out of the PC building scene for a while now, just built a new one a couple months ago.
Most things are pretty much the same, and the principles all still apply but it can be daunting at first.
