Can my power supply support r9 390?



Could you please list some good PSU's? I don't know the difference between Platinum, Gold, Bronze, and Certified.
 
dont mind efficiency, plays a little role on home pc.however it is more likely that you will end up getting a bronze or gold. platinum efficiency and above are very expensive. they are already listed. please go through the tier list.

EVGA B2 - GS - G2 and the newest corsair RMi / RMx would be my prefernece.
 


What about this one? Think it can support my future build?

very good unit, it will give you plenty of headroom if you ever decide to overclock
