Topic: which power supply to pick? (Read 670 times)
7950 around 170watt at 850mhz, probably enough for 3
Not to hijack the topic, but would a 750w Corsair support two 7970s, or a 7970 and a 7950? Also since heat seems to be an issue for my rig: would something like this be a good investment?

Corsair HX/AX series is usually a good choice.
dont forget to check amp rating, some 600 watt psu have less amps then a corsair 430. amperage is more vital in carrying large loads that just rated wattage. i was going to upgrade to a 600 until i realized my 430 corsair has more amps then many 600's. my 7850 under full load and overclocked to 1150 mhz only pulls my 12v voltage down by 0.03 volts.
Yes you should pay attention to what the different rails can put out. Some manufacturers rate their PSU a high total wattage and then stupidly put a ton of amp capacity into one of the unused rails which doesn't help anyone. They should get the "scammer" title hahahaha. 
Thanks everyone!!
Let us know how your build goes, or even take a few pictures of it.
Thanks everyone!!
stick to well known brands like Corsair, Antec and SeaSonic
stay away from generics or cheap ones like apower or superflower

I am using a 80PLUS Gold 850W PSU as written in this thread:

It will probably help you with other stuff as well.

Besides wattage you are going to want an 80plus gold PSU. I blew up a few 80plus bronze and silvers, before investing in a gold that is putting down the power 100% reliably for way longer.
Hi everyone, I'm planning to build a mining rig with 3 Radeon 7950 or 7970 mining rig. Does anyone know what are the criteria for a the power supply to support the mining rig and is there any recommended power supply? Thanks a lot!
