Power Supply Suggestions, going modular.

Makol · March 1, 2013

I recently got a BitFenix Ghost and with my current power supply cable management has been tricky so I think it's time to go modular.

Right now I'm looking at this power supply, it's $90 after using a promo code. http://www.newegg.com/Product/Product.aspx?Item=N82E16817182263&nm_mc=AFC-C8Junction&cm_sp=&AID=10446076&PID=6146846&SID=1n8uemv2qk4j2

Would this be enough to power two GTX 670s in SLI?

If there's something better that's below $100 any suggestion would be great. Also the promo code ends on the 3rd soa quick reply would be greatly appreciated.

It's a fine unit, (OEM is superflower I believe), but not enough for 2x670's in sli. The TDP of the 670 is 170W, and TDP isn't necessarily max power consumption. I would venture a guess that each of those 670's could pull close to 200W under load. Add in a processor, even with a low overclock on something like a 3570k or a 3770k, which are rather power efficient processors, that's another 100-120W minimum. If you're using something like an 8350, it's more like 200-220W. Add that to the two 670's and you're pushing over 500W with just the cpu and gpu's. Add mobo chipset, vrm inefficiencies, a drive or two, and a few fans, and you're pushing 600W minimum. I would go with at least a 750W unit if not 850W.
