cheap haswell ready PSU

David Junker · Mar 18, 2014

Hi

I'm looking after a haswell ready PSU. In another thread i got the Seasonic M12II 520w recommended. Sadly that PSU is not has well ready..

Afterwards i was looking around, and i can't seem to find a quite/silent and kinda cheap haswell ready PSU around 500W..

I've looked at Super-Flower Golden Green 80PLUS Gold 550w, but i can't find anything about it being haswell ready or not.

Other suggestions are really welcome!

If you are not using the new c6 or c7 sleep states then you don't need a Haswell ready psu. These new sleep states are disabled by default on every desktop i have seen.

But that wasn't my question.

The Super Flower Golden Green 550W (SF-550P14XE) uses a modern DC-to-DC convertor circuit to derive its +3.3V and +5V rails so it definitely is Intel Haswell Compatible.

It's the PSUs that are based on the older group regulated circuit design, like the Seasonic M12II 520W, that don't pass Intel's Haswell Compatibility test procedures.

All of the new Corsair CS Series models are Haswell Compatible according to Intel's test procedure.

Other Intel Haswell Compatible confirmed PSUs:

XFX TS Series non-Modular XPS-550-TS3 (P1-550G-TS3X)

XFX XTR Series Full Modular XPS-550W-BEF (P1-550B-BEFX)

Seasonic G Series 550W (SSR-550RM) semi-modular

Seasonic S12G Series 550W (SSR-550RT) non-Modular

Thank you! I'll go with the Super flower since it's the cheapest.
