Hello, I'm new to the forums so I hope I posted in the right place. My question is that I have a Xion 700 watt psu with two 12v rails and I'm wondering if it will run the GTX 570. One rail has 21 amps and the other has 22. I've been doing a lot, and I mean a lot of research on this topic and I'm more confused than I was before I started so any help would be gladly appreciated. Even a simple yes or no answer would make me happy. Thanks in advance.
You can check the power requirements for your PC by inputing your hardware into the PSU calculator at the link below. Your PSU looks as though it might be OK if you load balance the PSU by using one rail for the GPU and the other rail for the CPU and other devices.
xion psu hey....sounds like a generic POS. i would not trust it. see if you can find a review on that particular model. By review, i mean they actually have to load test, ripple, noise etc, not just plug into a medium spec pc and hook up a multimetre and say "yep, it puts out 12v, we will give it a gold award!"
