Crossfire amd 7970s with i7-3770k at 4.2ghz and Seasonic X-650 Gold PSU

post #1 of 4
Thread Starter 
Hello,

I'm thinking about adding a second 7970 to my rig posted in my signature and I was wondering if it was possible to run crossfire 7970s at stock 1050/1500 mhz clock speeds alongside an i7-3770k at 4.2ghz (using less than stock voltage and full power saving features). The other components in my rig worth noting are a Creative Titanium HD sound card, two Samsung 830 256gb SSD's in RAID 0, a 2 TB WD Green HD, a 1 TB Samsung 7200rpm HD, 8gb of G.Skill memory and six fans (5 x 120mm and one 200mm). I'm thinking that this rig will come in around 600-650w but I doubt it would ever be taxed at 100% anyway to utilize the full power of the PSU considering I am never maxing the CPU and GPU at the same time. The Seasonic X-650 is just over 3 years old if that makes any difference.

Thoughts?

You could do it but you would not have much room left

Thanks for the reply. I know I wouldn't have much room left but I don't see myself requiring high overclocks or anything from the cpu or gpu as by the time I upgrade from this setup cpu and gpus will consume even less power (i.e. haswell and gtx 780 and titan already use less power in comparison). I simply wanted to know if it could be done without me needing to fork out additional cash for a new PSU.

If you keep everything at stock no problem

With overclocks you might get close to the limit so that i would not do
