I am about to build a new gaming computer. I decided to buy the Asus ENGTX560 TI DCII TOP but then I noticed it requires two 6-pin PCIe connectors to work. The problem is my psu only has one 6-pin PCIe connector. Do I need to buy a new PSU?
Total of 38A, just barely. I wouldn't bet on it though. I wasted a card once with a weak PSU. Under the slightest load I put on it, even a video, the PC would restart, the GPU was overheating and I didn't realise that it was the PSU's fault until I had to take the card back because the lack of power had damaged it.
Always get headroom when you choose your PSU, it is the last part that you would want to cheap out on.
