HX850 for GTX 780 Ti SLI + i7 4930k ?

post #1 of 2
Thread Starter 
Is my Powersupply powerfull enough for my set up (corsair HX 850w) ? Or is it cutting it too close ? My 4930k is overclocked to 4.4 with 1.36v.

My Ti's are power hungry. They're going to draw 300W+ each on air, but of course them being on air will increase the power draw both from fans and higher temperatures. I was just curious what kind of power a more leaky Titan draws at 1.35V. eek.gif

I leave here for you a quote from one of my earlier posts:

"Did some testings today and this is for all those inquisitive minds out there wandering on the power draw of our beast cards running GK110!

Bear in mind that my system is in my SIG and the only difference was the CPU@4.8Ghz@1,30v! Using triple monitor 3240 x 1920@120hz SLI TITANS W/ Skyn3t Rev2 bios
and memory at stock 6000mhz!

1306mhz / 1,37v / power draw 124% / load 99% 372W
1333mhz / 1.37v / power draw 134% / load 99% 402W
1359mhz / 1.37v / power draw 139% / load 99% 417W
1385mhz / 1.37v / power draw 145% / load 99% 435W
1400mhz / 1.39v / power draw 155% / load 99% 465W

As you can see voltage alone will not increase power draw until you increase clocks and dynamically load your card, power was being drawn from the wall ranging from 850W - 1250W! thumb.gif"

Cheers

Ed

even though thats with a i5-3570K there won't be more than 50 watts difference.
