I'm new to PSU upgrades and just wanted to upgrade my noisy Dell one. So I ordered this one last night: http://www.newegg.com/Product/Product.asp?Item=N82E16817182018 Now as I was doing more reading on PSU's today I read somewhere that some of the newer GPU cards need about 24A on the 12V rail, which I'm assuming stands for amps. The one I ordered above says: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] I'm only going to be utilizing 20 pins on the main connector, since that's all my MB has, so I'm assuming the +12V1 is for the 20 pins and +12V2 is for the +4 pins. Am I right? Here's my system specs: 3.0 P4 HT 1GB PC3200 80GB 7200RPM BFG 6800GT OC DVD-ROM CD-RW Sound Blaster TV Tuner The only thing I OC is my GPU, but not by much. So will this PSU be good enough or should I return it for one w/ more amps on the 12V rail?
