Wahh! You're skimping on a brand a lot of people have recommended on here? Xclio's are great and for it's money, you get plenty out of it!
Well to DeadPixel, tell your friend to get the Xclio Greatpower 550W. 52AMP's is more then enough. Well when you go shopping for a PSU, try to get one that at least has about 30AMP's or more. That way, you'll know the more AMP's you have the better it is.
