How many watts for 120mm AIO cooler?

[monkeydelmagico]

What's the typical wattage draw for a 120mm AIO cooler? I imagine the pump mechanism would draw more than the typical 120mm fans alone. Anyone run a kill-a-watt test?

Not having had an AiO yet, I'm pretty darn sure the specs would include the amperage rating, and -- 12V x A -- you know the rest. Or just look at the amperage spec on several different water pumps.

The Kill-a-watt device is an AC appliance. Haven't bought one yet. Do they have some . . . DC option? I'd doubt it -- really . . .

I have the Kill-a-watt device. Never had the chance to measure the increased wattage draw of a single 120mm AIO.

However, here's a link to the spec sheet page of a COOLER Master 120M seiden. It appears total wattage used (I assume including the 120mm fan) is @ 3.7 Watts and the pump alone is 1.8 watts.
I stand corrected! I believe the pump alone uses up to 1.8 W and the fan up to 3.7 W so total for a single 120mm fan AIO @ 5.5W

Click on the spec tab for the link and read the wattage at the end.

Not a lot of juice, really. What's that? A hard-drive's worth? It's less than a 1A DELTA fan!! I'm wondering why the question. There must be gaps in some . . . PSU calculator . . . Don't mind me if I seem puzzled -- I started taking Medicare 2 years ago!

Thanks guys.

I'm doing my math to see if a Antec NEO eco 620 watt PSU will be able to power a pair of 7950's. Didn't want to overlook a possible power hog. Looks like the AIO pumps are very efficient. I would have thought they drew more wattage than that.

My back of the napkin calculations:
I'm running my 4690k processor at 4.3 ghz with 1.1v. Argus monitor puts it at around 60watts draw with full load. I'm guessing system minus GPU is somewhere around 120watts.

I'm running my single 7950 at 1ghz with 1.1v. Thinking the max draw would be around 150-200 watts.

That leaves me some room to put another 7950 in the system as long as I limit my voltage during overclocking efforts.

That sounds about right -- 150-200 Watts. I've always overestimated my PSU choices, but tried to temper them with Outervision. On the old sig-rig, this is going in the opposite direction: I replaced an older GPU with a newer more powerful one two generations newer, and got rid of a hard disk while increasing disk capacity by a factor of four.

So why did I pick an 850W Seasonic gold/platinum 80-plus, when a 600 would've been more than enough? Oh! I was thinking about the second graphics card I deferred buying . . . . which I never needed. The newest ones being the most efficient, I'm guessing that using two of 'em might still require a lesser power supply.

Which reminds me -- to order a Kill-a-Watt (or two) with the game-controller I have my eye on . . .
