PSU Recommendation

[ZyCeGrubby]

I need to know how many watts I need for the following build:

980 Ti (Gigabyte) + Reference GTX 660 that I have laying around 

5820k Overclocked 

Various LEDs, 6 case fans, 3 SSDs plus a harddrive

Currently I am going for 1000 watts but that may be a bit overkill. Is 850 enough?

[don_svetlio]

600W but the 660 can't work with the 980 Ti in one system

600W but the 660 can't work with the 980 Ti in one system

Well, you can put it in and drive a monitor but yeah, no SLI.

[Patrick Bateman]

650 is more than enough

quality tho evga g2, gs, gq NOT NEX OR W1,B1,G1

any xfx 

any seasonic

dedicated phsyx card?

[don_svetlio]

dedicated phsyx card?

that's been pointless for a few years now

[ZyCeGrubby]

Not running it for SLI, just to have more monitor outputs. Not going to use it for anything else but web browsing.

fair enough but i was just saying it would work so what you said wasnt necessarily true..

A good 650w would already be plenty. 850w or 1000w are overkill. 

If you would like some specific recommendations, it would help to link us to where you're shopping.

650W

I Prefer an overkill power supply just for upgrade room in the future

PCPartPicker says that without the 660, the Watts used is 571W. nVidia claims the 660 uses around 140 watts. That totals to 711 watts. I want to overclock the 5820k too. So around 750 watts. I also want room for upgrades so 900 watts would be nice. The cheapest reliable PSU here in Norway is the RM1000 (1000W if you couldn't guess)

That logic is wrong... SLI 980tis would be fine on 650W...

Psu calculators are unreliable and the wattage specifications on graphics card websites are generally inflated. Look at actual power draw benchmarks instead: http://www.anandtech.com/show/9306/the-nvidia-geforce-gtx-980-ti-review/16

The logic isn't wrong but the sources are unreliable.

"Load power consumption:

980 Ti - 388 Watts"

 

PCpartpicker says 250, which means it's not too much, but too little, which would imply that I need a higher watt PSU, right?

388w is the power draw of the entire system.

388w is the power draw of the entire system.

Oh. Should probably have read the whole thing then... hahaha. 

[ZyCeGrubby]

Okay. Decided for the 850w EVGA G2. Or should I go for the 750w version?

Like I said, 850w is overkill. A good 650w would already be plenty. If you're going with a G2 anyway, go with the 750w.

Alright then. You just saved me Around 80 bucks
