1000W or 850W ?

[Alexalex1]

Im doing a x99 build and can't decide on 1000w or 850w power supply. The build is going to have a 5820k and 2 gtx 980s in sli. Everything will be custom watercooled and overclocked.

750W

EDIT: Just so long as it's a good PSU I mean
If you want to go with Diablotek then even a 2kW PSU won't be enough

750W is plenty.

[AresKrieger]

Yeah 1000 is way overkill 750 should be ok, assuming the pumps don't use 100+ get a high grade 750

WTF is this thing it looks like it is for melting steel not for powering a computer

[Alexalex1]

I forgot to say it will be in the 900d with 13 fans and watercooled. extreme power supply calculator says i need 883w.

I would suggest  850w, just to be safe(dual 980 ti can draw even 800w when oced)

EVGA G2 or GS in that case.

Check the reviews - over 30% negative.

Brings back so much memories of old times

PSU calculators are retarded - really really really retarded. Get an 800W if you want to be sure but a single fan uses 5W - 13x5=65W for the fans.

Yep your cooling uses over 100 watts as I thought might be the case

I'd say it depends on a price, the 850W should be enough, but if the price difference between it and the 1000W one is only marginal, then get the 1000W. Alway better to have more headroom for future uprades, it doesn't draw any more power than you need anyway...

lol no don't

dont use PSU calculators

they are always wrong

they need to account for cheap crappy PSUs

 

but as long as you get a good quality PSU you can ignore those calculators

look on google images for "980sli power consumption"

that will tell you how much you really need, based on real world testing

use coolermaster's http://www.coolermaster.outervision.com/

it recommends 586w but thats without 13 fans and watercooling

[AresKrieger]

EVGA G2 or GS in that case.

I thought they were regular 980's

[don_svetlio]

A single 980 uses 240-ish watts. 2x use about 480. + 200 for everything else = 680. + 65 for the fans = 735. And keep in mind that's only if you get an EXTREME OC on stuff

[AresKrieger]

Yeah 800 is good then so 850 should be fine

[don_svetlio]

13 fans use 65W >.<

Yeah I agree but 100 headway really won't affect the effeciency more than 2% so if he want to spend the money 850 will be fine

[Alexalex1]

OK so what i read that eveyone says 850w is good for a 5820k 2 gtx 980 sli  on custom watercooling and overclocked 

[AresKrieger]

Yep unless something is broken it should never go above 800 W under even the worst conditions

[don_svetlio]

If he gets a SeaSonic S12G 750W it's like he's buying an 850W. Depends on the PSU
