I have a Sony Vaio (PCV-RZ32G) and I believe I need a higher wattage power supply. The factory installed PSU is 300 watts. The problem I have ran into is that Sony made the power supply an odd size so I can't find any power supplies that are the same size with a higher rating. The size of the factory power supply is 4"d x 3.5"h x 6.5"w (looking at it from the back side where the power cord plugs in). I have checked the computer stores around where I live and even drove 1.5 hours to Fry's Electronics in San Jose with no luck. I have upgraded a few hardware items. I don't really want to buy a new case, I like the way my factory case looks. Any suggestions or thoughts would be greatly appreciated.

Are you sure you need a more powerful PSU? Use this Calculator and make sure before you lose your mind trying to find one that fits.
