I'm going to be getting something along the lines of a 7800GT or x1800XL along with a DFI nF4X Infinity in a few months, and I just wanted to know if my current PSU is up to the task of powering the video card. The only things that the PSU will be plugged into will be the motherboard, 2 optical drives and the video card. I use my 2ndary PSU for all of my fans and lights. Do you guys think that I will really NEED a new PSU? Mine does awesome on my current setup, 5V rails have never gone below 4.99V, the 3.3V never below 3.2V and the 12V has never gone below 12.12V.
