"The Ultra X-Finity 800W and X-Pro 800W power supplies are pretty much on equal ground when it comes to performance. The only real difference between them is; the X-Finity is black and comes with FlexForce cables, the X-Pro is silver and has sleeved cables. Both have plenty of leads, two 80mm fans and thick aluminum housing. Either one of these power supplies is well suited for a hardcore gaming rig. Watch the video to find out more and check out the bloopers at the end." ~3dGameMan.com
