I bought a geforce gtx 550 Ti which apparently i don't have enough watts to play, sorry noobish at this. anytime i launch a game my pc instantly cuts off and only way for it to come on is if i unplug the power and plug it back in from the back of the case, when im idle on the net or watching vids its fine, but once a game launches my pc cuts off, and the gpu also requires 400 watt or greater psu with a minimum of 24 amps on the +12 volt rail. and i didnt want to buy a crappy psu and it not pushing the right watts or cant support my mobo / gpu, any advice or links to compatible psu's would be great, thank you.
will that even be enough 600? cause my current psu is xion 580w, and my pc is cutting off with the gtx 550 ti, and that's what puzzles me cause i figured 580w is enough cause i dont have no external hardware plugged in, i even unplugged 2 extra fans and tried to launch any game and my pc still shuts off, leaving me to think that my current psu cant support the minimum 24 amps on the +12 volt rail that the gtx 550 ti requires but has enough watts
