Hey everyone, hoping to get an MSI OC R9 280x for pretty cheap later today but don't know which PSU to get, I looked at other ost and they discussed current etc and honestly I don't know what is ok and what isn't. Hoping you guys could hep out.

Three I looked at were:

Rest of the build is here for refernce:

Already over my budget so trying to get this PSU as cheap as I possibly can

Thanks guys!
