Asus gtx 660 to SLI Question

post #1 of 7
Thread Starter 
Hey guys I'm putting a few upgrades together for my current rig and was curious if a corsair ax850 would do the trick. I have been looking on the interwebs for a few days now and keep coming across yes and no. This is what I have in mind.

Asus Rampage IV Extreme
SB-E 3930k
Custom cooling loop w/ UT60 420 & 240 rads

I will be buying one of these cards soon and was planning on going sli in the future when I can afford it and the games I play need more power.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814121656

I will more than likely be OC the GPUs at least mildly (hoping to get it close to the "TOP" card that seems to be sold out everywhere) and I'm gonna be going for the highest CPU OC I can get out of it (4.7-5.0).


Will an ax850 be adequate or do I need to step it up to an ax1200 or equivalent?


Thanks in advance guys, I just don't have a clue eek.gif

More than enough. You'd be good with a 750W.

Thanks for the quick response. The only reason I was really curious is I read a few reviews that peg those GPUs at 250-350w OC'd while under load each and the CPU at 250-300w while OC'd and under load. Just had me worried.

a good 650 watt PSU can do 660 SLI with ease

That was likely the voltage at the wall while testing the card. The 660 itself draws less than 150W.

Hey thanks guys. You put my mind at ease. I think I'll take your guys advice and just get an ax750 and save myself a few bucks since I wouldn't need the extra overhead anyway.
