Water Cooling and PSU requirements

post #1 of 8
Thread Starter 
So I'm thinking about putting my rig under water but I'm wondering if I have enough power remaining to be able to without changing my PSU......again....

Any feedback you guys can offer is much appreciated.

Water cooling gear doesn't use all that much power. Few fans and a pump, what maybe 25w or so?

This. Most pumps are 24 watts or less(24W for a D5 @ 12V, 18W for a MCP35x @ 12V). Fans take very little wattage. Gentle Typhoons, for instance, only require about 4 watts at startup and only about 1 watt while running. I doubt you'd need more than an additional 35W or so to handle all the WC gear

As was said already, WC components require very little wattage.
Even 2 pumps and 30 GT fans, which is pretty extreme, won't even burn 80W at full speed.

Where the extra wattage requirement comes is in the OCing.
WCing will allow you to OC your board more. So that might make a bit of difference.

I say try it with what you have, and later upgrade your PSU if you need more once you have your loop running.

You do have a 850W PSU to run 680x3 and a CPU.
So that's getting close I think.

Cooler doesn't use much power.
post #7 of 8
hmm this has me a little baffled
which 680 do you have i only see 2 680s on evga site
and both of them require 195watts each which
just for them come out to 585watts
base clocked 3930k 193watts not sure what your voltage is for overclock
that already puts you at 778 watts
you figure 25 for the cooling system makes it 803 watts before the cpu overclock

im sorry but i can't see where 850 is gonna leave you much for upgrading anything as
that only leaves you 47watts
