Help on reading PSU specs..2 rails or 1? Tags: Power Supplies Graphics Cards Components Last response: May 2, 2012 10:21 PM in Components Share rbennett1701 May 2, 2012 9:50:18 PM I have a FSP300-60THA PSU, and need to determine what kind of video card I can run on it, but I'm not sure how to read the following info: +3.3V@6/20A, +5V@20/10.8A, +12V1@8A, +12V2@14A, -12V@0.8A Does that mean I have TWO 12volts? one at 8amps and one at 14? The reason I ask is because I am wary of dropping a discrete card (Radeon 6570) into a single rail PSU. Thanks!
