Get a gold-rated PS no matter what.

Can I ask, why you recommend gold PSU no matter what? I've heard others recommend silver or gold also.
Personally I got a bronze rated PSU (900w , running 3x7950) and I'm not sure if it's good or bad.

@op sorry to hijack thread.

That's a good question, bronze, silver and gold are just efficiency ratings. The lower the efficiency the higher wattage you need the PSU to support for the same load (you never want to max out the PSU at full load). The second side is higher efficiency means less loss to heat which may be a consideration. Although the PSU is going to produce far less heat than a stack of GPUs so it may be a moot point.

In the end its probably best to pick based on cost ratio, lots of gold PSUs are considerably more expensive and may not be worth it over just getting a higher wattage bronze to make up for the efficiency loss. Check the specs and figure it out from there.
