I'm looking into a good PSU that will help me power a system with the following specs: amd 64 x2 6000+ 3.0 ghz processor Geforce 8800gt 512mb video card 2 gigabytes GSkill gaming RAM ASRock Aliven NF6G mobo 160 gigabyte western digital hard drive 7200 rpm and 2 case fans I was looking at a 500watt thermaltake purepower power supply priced at around 54 dollars on newegg. But I noticed on another thread that the amperage it provides may be lower than I need, so I need a second opinion, and if this one is inadequate, a similar PSU that provides the power I need for about the same price and maintains quality, a.k.a. >70% efficiency at load at the very least. PLEASE help me because I want to make sure that this system will work when I put it together. Also, I would appreciate any other opinions on the hardware I'm choosing. For instance, the mobo. I'm not sure whether or not I should buy that particular model or not. If anyone has a suggestion of another good quality gaming mobo for about 60 bucks, please suggest it.
