7970 Quad-Fire - Page 4

post #31 of 52
Hey there.

I have a very similar setup to what you are looking at. 1500W is enough as I run a myriad of accessories (2 pumps, 18 fans) on my NEX 1500W unit that powers everything.

Could 3way CFX 7970s and 3930k be ran off a 1000wat psu or is that cutting it close?

I would feel better with a 1200w unit. Now, you most likely would be able to run quite fine, however once you start OCing, the power draw racks up quite quickly. Also, all units run MUCH more efficient when not running at 75 percent + of max load.

@OP, you should be good with at least a 1350W PSU, although I'd recommend going for the 1500W PSUs.

Enermax does make a 1500W version of the Platimax.

The power draw was probably close to 1300W because if I tried 1150 on the core the system would shut down almost immediately (all GPU's are good to at least 1250 in single card). I even had to use Molex to 6-pin and 6-pin to 8-pin adapters to get it all off the same PSU lol.

With this in mind, I'd say you'll be good with a 1500W PSU.

This is a bit off topic, but did you have to remove the GPU reactors with 4 Lightnings in Crossfire?

Looks good. Don't think that sound card would fit though with quadfire. Just use onboard. Also G.Skill TridentX 2400 would look a hundred times better with that motherboard. Lastly, this is just my personal opinion, but get 7950s instead. Barely less performance, but a good amount less power consumption. You won't have to worry about the PSU handling it plus your electric bill will be less at the end of the month.

to solve ur psu issue u can use 2 - 1000watt psu ..i have done the same and have a similar setup quad 7970 / sr 2 etc . u can connect a dual psu cable to it and configure the load accordingly .
plus u will have a decent head room for over clocking

I know they do but I live in the USA. They only make them for 240V AC standard and we in the US have to be different and use 110/120V AC tongue.gif
