Forget the damn WATTS, look at AMPS on the single 12v rail.

You are 100% clueless and no help to the OP, so touché fool.
just thought i'd tell you
watts = amps x volts
you're telling me that the 12v rail supplies 12v
so i'll tell you that given that volts is a constant, amps and watts both increase linear fashion![]()

You done Trolling as its not helping the OP!
@ OP, sorry I cannot go on when a fool trying to be smart says I pull figures out of air (assume he means thin air) after I posted links.
He has such a boner for wattage he does not know the amps on each rail are important.
I am done.

This is really helpful indeed and i suppose its time for a psu upgrade, if you wouldn't mind going the extra mile would you help me find a suitable one so i don't make the same mistake again? I was looking at this one a few days ago: http://www.overclockers.co.uk/showproduct.php?prodid=CA-004-EA&groupid=701&catid=123&subcat=2464

And I did tell him to lower GPU clocks if you READ.

and if you haven't already realised, the ocz zs has only one rail
@ savgebeast, That EVGA is a good PSU for price and made by SuperFlower so look at the Superflower Leadex range also.
Yes its overkill but again a good price and a very strong single 12v Rail with 83 AMPS.
You have not mentioned your CPU etc.

I take it the OP has 2 x 8 pin pci-e cables plugged in?
If the card was faulty I would expect it to have the issues every time it was under 3D load.
I'm presuming this is the PSU in question.

If you read it, it doesn't instil confidence.
It is rated at best for a mid range system.
I would be looking at the PSU failing/not being up to the job.(IMO)
