ZM-600HP enough for 2xHD7950?

Hardware PSU

Is it?

And If I overclock do I crash my system?

You'd need to bump it up, if you wish to accommodate two cards.

I would be worried running two cards on that psu

Thanks for the comments.

I forgot to mention the PSU is Plus version and CF certified.

I'm going to test this in CF anyway. It still has warranty left ;)

After testing my setup watt meter shows around 530W-600W draw at full load. Mostly ~600W.

Great, now I may have PSU and motherboard bottleneck (8x+4x pci-e 2.0 speeds).

But so far no problems have occurred.
