Ok here's the deal, I have a evga gtx 650ti which i just RMA because it showed display artifacting. Now I'm not sure if it was because it was faulty or if my power supply was not enough. I have a Antec 550 watt power supply, giving power to a AMD apu quad core on ASRock FM2A85X and one hard drive. Hopefully you guys can tell me if I should get a new power supply or not. Thanks for the help!

550 watts is more than enough power for your current setup. How old is your PSU?

@mikey87144: less than a year

550 Watts is plenty, artifacting is usually from card failure.

550 should be enough. If your power supply were the problem, you would notice other problems not artifacting, the system would crash completely from the CPU not getting enough power.

Alright thanks guys for putting my mind at ease.
