Triple 23'+470 SLI=PSU?

post #1 of 11
Thread Starter 
How big of a PSU will I need to be able to run 3 23' Acer monitors and 470s in SLI?

I currently have an 850w Corsair PSU. Will that be enough?

Just curious, why do the number of monitors matter? Do the number plugged into the gpu create more draw from the gpu itself?

I don't think so, I mean it shouldn't the monitors would go directly into a wall outlet.

850w will be just fine. You should only draw about 600-650w at most so you'll have plenty of headroom

Your current PSU has plenty of headroom on top of two 470's. Where can I get 23-foot monitors?

The number of monitors don't matter except in the case of idle power consumption. The card will consume more power when connected to two cards than one.

While an 850w PSU is more than enough; the question holds an interesting point: Surround makes GPUs work harder than Furmark on a single screen, no matter the settings (I see far increased temps and power draw running in Surround) or even Folding@Home. Surround-gaming stable overclocks on my GTX460s are around 100MHz lower than Folding/single-screen clocks for a given voltage.
