Hi I'm thinking of adding a Powercolor HD5750 to my OEM comp since I can get it for Can$80 but I'm getting more confused the more I read about psus and amp requirements.
Athlon II x2 2.7GHz 215 (Regor)
3GB DDR2 400MHz
Win 7 64-bit
250W PSU (which'll have to be replaced ofc)
I'm planning to run games like ME/ME2, SC2, HL2, Portal2, CoD, AC2 etc. My monitor is 1600x900
I need to know if I need a high amp psu for this?
I want an affordable psu (<$50 would be great) and 400-500Watt seems more than enough but some only have one 12v rail at 18-28A. The guide in these forums says to divide recommended wattage by 12 so for HD5750 the AMD site lists a 450W+ psu: 450/12 = 37.5A PSUs that list 40A on 12v rail are all 800W+ models
