I was running a corsair cx600, with a firstname.lastname@example.org/hd-4870's.
It ran fine. Passed prime95/furmark tests.
I bought a A6-3650/gigabyte combo on sale. Ocz Fata1ly 550 on sale too. The A6 is clocked to 3.5ghz/550mhz 320 shader app stream/open cl proccessor. Same hd-4870's.
It passed the tests fine.
The corsair has a single 40 amp 12volt rail, and the ocz has two 25 amp rails.
The fan is a bit bigger and quieter on the ocz.
120mm fan vs 135mm fan means the ocz is a bit larger than the corsair.
The modular feature is useless on the ocz since they just all get plugged in anyway.
It ends up being the exact same wiring and plugs as the non-modular corsair.
Both tested to be enough for a overclocked cpu and crossfire hd-4870's.
