I'm thinking about buying another 7950 (or R9 280) for my system and I wonder if the Seasonic G650 I have is enough long term. I used one of those PSU calculators and it would seem to be enough if not for the capacitor aging (?) pushing things at or over the limit.
Specs in my sig, The 7950 I have is at 1.25 V overclocked, i7-4770K is using up some 1.27 V with adaptive spiking to 1.36 - 1.37 under load. I also have 2 7200 rpm HDDs + 1 5900 WD HDD (games are on the Samsung SSD though, and I only use one of the 7200 rpm HDDs for downloading while gaming).
