My old power supply was bad so i sent it back and I want to make sure i'm getting the best one i can get.
Cpu: AMD FX 8320
Mobo: Asrock 970 pro
Gpu: Asus raedon HD 7770 2GB
HDD: 250 gig seagate
My old one was a 600 watt i tried using a 450 watt i had lying around when it broke and that didn't work so i'm not sure if something else is broken or what but I need a new PSU nevertheless.
