PSU for quad 7950's or 2 x 7950s and 2 x 7970s

post #1 of 39
Thread Starter 
Hey guys the title says it all. I'm looking at either quad firing 4 7950s or running 2 x 7950s and 2 x 7970s and was wondering on a recommendation for a PSU.

I really couldn't find anything online that was definitive and Google was less than helpful. I'm torn between either a 1500w gold certified unit this one,

http://www.newegg.com/Product/Product.aspx?Item=N82E16817194106

Or this platinum certified 1350w unit,

http://www.newegg.com/Product/Product.aspx?Item=N82E16817194105

Both units are on sale right now and also come with a mail in rebate. Both are the same price before any rebates and after rebate the 1500w unit ends up being $10 more.

I would just like a few opinions on which unit will be a safer bet with four cards running ~1.15ghz @ 1.2v, a RIVE w/3930k running ~4.5 GHz @ 1.3v, two D5 pumps, 17 fans plus a controller, four sticks of DDR3, two SSDs and a few LEDs.


All of the calculators I tried varied greatly. Neweggs PSU calculator was at 1362w and the enermax one I found was 1056w. I just want to make sure I have enough juice with a little room to spare.

Thanks in advance guys!

Yeah I'm kinda of leaning toward the 1500w unit for the price. I just wasn't sure if that was more than I needed lol.
