I'm not a knowledgeable guy when it comes to PSUs, so I have some questions. 1. When a PSU has more than one rail, do you add up the amps to get the amperage for that PSU? - Scenario: I have a graphics card that requires at least 22 amps on the +12 rail. The PSU has 2 rails, both at 16 amps. Would the graphics card work with this PSU? Total, the amps is 32, so I'm wondering if that's how that works. 2. What are good brands of PSU to consider when purchasing? 3. This deal is so tempting for me, is this a good PSU? Newegg.com - COOLER MASTER eXtreme RP-500-PCAR ATX from factor 12V V2.01 500W Power Supply 110 - 115V/220 - 230V Nemko, TUV, cUL, CE, BSMI, FCC, CCC - Retail Do you think this would run my setup? (see PC profile) Thanks a bunch.
