My current system is an HP Media Center. I just got a 8600 GT Graphics card-need to upgrade the PSU before I install it since I only have a 300 in the standard system. I am also going to get a cheap AMD X 2 6000 from a friend that went to a Core Duo MB. Will 450 be enough? I am not a hardcore gamer-not going to do SLI or anything like that. I may play the occasional 3D game, but I mostly use it for internet and audio processing-I am a "amateur" musician.
Any assistance would be appreciated
Yes 450W will be fine. You have to watch the amps on the 12v line. My recommendation is the Corsair 450W VX which has 33 amps on the 12v line and you can get it from Dell for $59.95 after $10 MIR.http://accessories.us.dell.com/sna/productdetail.aspx?sku=a1262687&cs=19&c=us&l=en&dgc=SS&cid=25682&lid=585555
