Is 850 watts enough for SLI 680s and Water-Cooling?

I recently built a new machine and I'm thinking about adding Koolance water-cooling system. I plan on cooling my 2 EVGA GTX680s and my i7 2600k.

The plan is to purchase the Koolance Reservoir and Pump, RP-1005.

Heres summery of my system specs:
i7 2600k Over clocked to 4.5Ghz
2 SSDs - Corsair, Intel
1 TB HD Western Digital (3 years old)
2 EVGA GTX 680 Superclock's
1 plain old DVD drive
4 120mm Fans and a 200mm Fan (may be 5 120s if I Push-Pull)
RAM Cooler
16GB Corsair Vengeance @ 1600Mhz
Corsair HX850 PSU

Also, if anyone has had any experience with "Reservoir and Pump, RP-1005 " let me know.

  1. Yes, you could run 3 of them, maybe even 4 with that PSU (but I wouldn't)
  2. So these water-pumps don't draw a ton of wattage?

    I knew that the 850w was overkill for my system I just have no idea about the pumps.

    Thanks for the quick response. I literally just joined like 20 minutes ago. I wish I had joined this site years ago.

    Thanks again.
  3. Not really no. And you're welcome.
