Power consumption question

[Kevin5239]

So I'm building a desktop and I just wanna make sure my corsair tx850w psu will be able to handle my setup.

Mobo- z77
Gpu- gtx 670 (possible plans for sli in the future)
CPU- i7-3770k
CPU cooling-corsair h100 liquid cooler (7 case fans)
RAM- corsair vengeance 16gbs

I'm not worried about the other components drawing to much power.

Opinions?

Would that work though if I were to go sli with the gtx 670

You should be fine.
Recommended power supply for a system with a single GTX670 is minimum 500watts total power with minimum of 30amps on the +12v rail, SLI minimums 650Watts or greater and ~38amps or greater:
Your PSU has 70amps on the 12V and 4 PCI-E connectors for the video cards. It should be more then sufficient for your system.

Absolutely. That's what I meant.

Each GTX 670 is a 170W card: http://www.hwcompare.com/12500/geforce-gtx-670/
That relates to ~14.2A on the +12V rail for each card. The 77W processor (at stock) only adds about 6.4A. The wtr cooler adds about the same. fans are miniscule; 1/4 amp maybe.

I used to have 2 x GTX 570s in the rig in my sig. They were 219W cards each. I never came close to the capabilities of my 850W XFX PSU.

Awesome, thanks for the info and link.
