So I want to buy the R9 390 Graphics card for my computer and I realized I needed to get a better power supply I was wondering what power supply would work well and is compatible with my computer?

1| You will need at least 650W of power from your PSU but I'd ask you to keep some more for headroom.
2| It'd help us if you could provide a budget and a site off which you'd prefer to purchase off of to help us in narrowing down a worthy PSU for you.
3| ATX based PSU's are compatible with your unit.
