I need a low priced PSU to replace the 250W one that my HP Pavilion a6110n came with. My friend just gave me his old ATI Radeon™ X1600 which requires 350W. Trying to be able to play World of Warcraft on something other than this integrated card. If anyone could give me some suggestions or at least tell me what I need to be looking for to find the proper PSU that will fit into my box, I'd really appreciate it. Thanks.
