Well I want to get the new rx 480 8gb for my pc. I was told that my power supply is ok but it's unstable so I need some help looking for a power supply. If someone could find a good power supply that would be great and would be very nice. I was looking at EvGA and corsair power supply's because I hear they are ok. If a smart computer guy could help me that would be great thanks. Also wanting to spend only around 120 for a power supply
