I have a 600w Seasonic that has 4 connectors that can plug into my DFI mobo. There's a 24 pin, a P4 4 pin, a regular 4 pin molex, and a small white 4 pin. I've been testing an Antec 300w PSU on this board to try and figure out why the computer won't work, but there's no output from the video card. Am I just not giving it enough power or are those other connectors necessary? Thanks!
