Could my PSU be faulty?

[Barso]

I am using a tagen piperock 1100w PSU and it should be enough to power my EVGA classified, core i7 920 and GTX295 but I get stuttering in some games like world of warcraft and doom3.
I know they are old games but I have tried everything to fix it.
Is it possible my PSU is faulty?
How can you tell if your PSU is supplying the right volts?

If you're only experiencing problems in the above 2 games i suspect it's a OS/driver/patch issue. And if it is you will be better served by posting in their dedicated forums outlining the problems your getting - or even the Game Forum here.

If your PSU is firing on all cylinders you have enough wattage to power 2 rigs of similar spec.

If you still want to test your PSU, these are links from Huddy's site - it has a step by step guide on how to 'Use a multimeter to check your PSU' and one to 'How to check if your PSU is faulty'

Sounds like a driver / software fault more than PSU.
