Help on PSU

[mario7770]

I recently bought a
600watt Raidmax Cobra 80+ Gold RX-600AE PSU to powerup my new r9 270x vapor-x gpu!

I heard so many bad reviews as well as good ones! so what do you suggest?

Its a tier 5 PSU, the worst of all. Sorry to use that word, but that's what the masters of PSU and numerous reviews say about it. Get a Tier 1 or 2 PSU if possible. Reference:
