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.


my case: http://www.directron.com/xsniperggn.html

my mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

GPU: http://www.evga.com/Products/Product.aspx?pn=01G-P3-155...

and the PSU i thought might meet my requirements for all 3 : http://www.newegg.com/Product/Product.aspx?Item=N82E168...

geforce gtx 550 Ti minimum is 500W, the 520 - 600 will be good
Seassonic 520W http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or this 650 gold http://www.newegg.com/Product/Product.aspx?Item=N82E168...


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

That's because your PSU is a cheap Chinese garbage one, it can't deliver it's labled output. The Corsair you picked can power up a very high end PC with GTX 690 inside.

Yes exactly. As long as you can afford it, even though you won't consume half of it's output.

A true quality 500W PSU can still be very sufficient.
