I have a seasonic 550w modular psu 80 plus gold and a evga gtx 780 that says it needs 600 watts and a min of 42 amps on the +12v rail i have 45v but will 550w be ok or should i upgrade
Yes; that PSU is more than sufficient. The recommendation is for the system running the graphics card. The graphics card itself will not use up 600W alone.
