Is a COOLER MASTER Silent Pro 1000W PSU enough

Thinking about getting a 7990 to Trifire with my current 7970 vapor-x. Anyone know if my PSU will hold up to the power requirements?

Best solution

It should. It's a tier 3 PSU.
Not the best, but good enough. Each HD 7990 is a 250W card maxed out. That's 21A on the +12V rail for each card at max. 63A just for the 3 cards alone. You'll find out how good the PSU is built, that's for sure. If you don't trip a circuit breaker.

I don't care for that Cooler Master PSU , it's not the greatest quality.

I wouldn't push that unit into a tri setup.
