Will I need 850w or 1000w?

[AndyKala]

I've been doing a lot of research to see how many watts is really needed for EVGA GTX 1080 FTW 2 - SLI. I'm running skylake (i7 6700k) AIO 240mm radiator. I have about 6 120/140mm fans. I do have some LEDS as well. I do plan to overclock everything to. Would I need 1000w? Forums I've been reading have different answers. Some say you should get 1000w, others say 850w is more than enough. I am reaaallllyyyy confused as to how many watts I'll need. I trust these forums the most, so you guys are the tiebreakers

If you put all of your parts into a pcpartpicker.com list it will show you total system watts so you can get a baseline of what psu you need.

850W would be more than you need for something like this.

PC Part Picker doesn't have the correct wattage for the EVGA 1080 FTW, plus I wanted to hear your opinions on how many watts would be better to invest in.

Do you plan on doing any SLI?

I've got a 1200w but it's possible with a 850.

 

I've got the same computer you do. H100, with push pull, 3 front fans 1 rear fan and sli 1080's. 

There's an AX860i in my pc right now. Whenever my AX1200i gets back it's going back in. Broken connector on my 1200.

How many watts are you drawing from the wall?

[comicsansms]

750W is more than enough for a Dual GPUs set-up, you could even get away with a 650W unit.

Two 1080s would be more than fine on a 750W PSU of sufficient quality. An EVGA G2 750W isn't crazy expensive and should do you nicely.

Idle says 264 in Corsair link..

I'm pretty sure I'll get Corsair RM850. It seems like a good PSU.

Well I would think that 850W should be fine for that setup

Oh ok, that's good. I guess I won't need 1000w.

The RMx and RMi are much better. Don't grab the yellow RM unit.

What really? I thought their RM series is better than RMi and RMx.

[Coaxialgamer]

750W would be more than adequate for this . Even if both 1080's (OC ) use 200w each under load , you still got 350w left for the cpu ( 100W-ish ) and the rest of the system

Witch is better, RMx or RMi?

VERY little people actually need 1000w.

There's not that big of a difference. Consider other options too like EVGA.

Doesn't Corsair and Silver make the best PSU's on the market?

Take into consideration that Corsair link is terribly inaccurate.

 

I have a 3930k + 2x R9 280X, at idle Corsair Link showed around 240W, with a dedicated power meter It was around 160W.

The RMi has a fluid dynamic bearing fan and has Corsair link capabilities. In Corsair link you can switch from multi to single rail operation and vice versa. Worth it to get the RMi IMO.

This too. Although the RMi is my favorite power supply (due to the flat 24-pin) the G2 is better value.

Don't know who Silver is but Corsair doesn't actually "make" the PSUs as they have OEMs to do that, so not all of their units are consistently good like the various RM units, AX, etc.

Corsair Link is more accurate on the RMi these days due to the hardware within the RMi being able to measure voltage readouts better than older -i PSUs.

You know a lot about PSU's mate. I've never met anyone with such passion for them. That's a good thing though! Thanks for the replies.
