How close can i cut it?

Hey guys,

I am having issues with the PSU setup on my mining rig, forcing my pull more than i'd like from my OCZ ZT750.

The rig will of course run 24/7.

Now the problem is, that measured the plug, im pulling about 760watts on the PSU.

How close can cut for a 24/7 rig?

760w from the plug, with approx 80% efficiency means you are only pulling 608w from the psu
sounds like it should be okay to me.
