Is my PSU Haswell compatible?

Hi there.

I have a Super Flower Golden Green HX 350W PSU - does anyone know where it is Haswell compatible?

I cannot find the information anywhere.

Thanks.

Connectors should be ok, just make sure it's powerful enough.

I would say no, but you can use it if you turn off the CPU C7 sleep state in the motherboards bios.

It's DC-DC PSU with lower rails made from 12V.
(unless different from higher powered models)
So it doesn't care about load distribution to keep voltages regulated.

Thank you (I am a bit irritated to realise that I did not put this thread in the PSU section).

I have just had a look at my BIOS and C7 sleep option is squirreled away in a CPU section that I had never seen before (it was off).

It really isn't clear but, as EsaT says, my PSU does seem to be likely to be DC-DC which, apparently, is not affected by the C7 sleep state.

I have turned it on (changed it to Auto), to see what happens.

What is C7 sleep, anyway?

Is this when the system goes into hibernation?
