I went to the Dell forums and a member posted this website http://www.pcpowercooling.com/home.htm This website allows you to specify which system you have and it will give you an optimal PSU. Well.. the "optimal" PSU for my dell 8200 was a silencer ATX 400 but the wattage is 300W. I was thinkin of gettin a 350W or maybe a 400W PSU for a gf fx5900. Is this PSU good or is there another that may be better for my system compatibility? Thanks.
