I am going to buy AMD 7790 or AMD 7850 GPU. What i have now is 400WATT Vision PSU (18A @ +12v Rail).I really don't know much about PSU and what are the things to look for in a PSU (mostly PSU are that are avl. in BD)
** Calculators Recommend 370WATT PSU for my Entire System including both the card!
Suggestions are Truly Appreciated!
