1200w for 1080ti 3 way sli

99% of games do not support multi-GPU, so it is in fact no gain to add more cards.

Here's at least 500+ games with SLi support from Nvidia:

I guess if you want to be autistically correct it could represent the 1%. But there are games out their that support it. As long as the games that OP plays support it then that's fine. It also isn't hard to use AFR 2. 

 

I've had success in BF4, Fallout 4, Crysis 3, Titanfall, DOOM and few others for SLi support. 

 

And SLi is also an enthusiast thing. Maybe OP finally wants to ascend.

Yea I see, but even if it does use 1200 watts the Evga p2 can provide something like 200 watts over this.

Yup. PSUs have overdraw. My 850 G2 can overdraw to about 1200W from the wall. Maybe further but haven't tested.

No, they actually don't, but you can find out for yourself.

They don't support it natively, but you can get it to work.

So true it hurts

1080ti uses up to 250 watts , if you leave it be and don't mess around with overclocking.

 

So three of those would use up to 750 watts, which means even a 950-1000w psu should be enough if you don't OC your processor as well..

Yea but wouldn't an overclocked system (gpus + cpu) and a possible watercooling loop (cpu) be really close to 1200w?

So true it hurts

The card uses up to 250w with the default features, where it boosts or lowers its frequencies automatically... and in TORTURE mode (benchmarks) or when it's very gold (the efficiency goes up a bit when card gets warm). In games, once the cards are warm, the maximum power consumption is somewhere around 215 watts.

With 3 cards in SLI, rarely all three will be used to the maximum, so in real world they won't use 750 watts. My guess is they'll probably average around 500-550 watts, but staying with 750w just for safety.

 

If you don't believe me, see the pretty graphs on this page: http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-ti,4972-6.html

 

Modern processors with 65w-95w tdp won't use more than 100-50w... if you overclock them you add 50-100 watts more.

 

A good quality power supply (for example a Seasonic gold efficiency one) would have some safety margin.. often a 1000w psu would actually be able to output 1100 watts with no problems at all for small periods of times.

 

Anyways... my advice would be drop a card and stay with just two 1080tis and use a 850w psu. 3 way SLI seems like not really worth the effort.

Actually I didn't want to go with 1000w it was more ether this 

220-P2-1200-X1_XL_1.jpg

Or this 

120-G2-1600-X1_XL_1.jpg

But now I know 1200w with platinium effiency will be enough, thanks :) 

Spoiler

Will probably do a build log though

If you're going to blow that much money on video cards, why are you niggling over PSU wattage?  Just get the 1600W one, your dick will feel bigger, and you'll never have to upgrade or replace it.  The AX1200i I have in my storage server has been around for the last 5 years in 3 systems.

Workstation:  13700k @ 5.5Ghz || Gigabyte Z790 Ultra || MSI Gaming Trio 4090 Shunt || TeamGroup DDR5-7800 @ 7000 || Corsair AX1500i@240V || whole-house loop.

LANRig/GuestGamingBox: 9900nonK || Gigabyte Z390 Master || ASUS TUF 3090 650W shunt || Corsair SF600 || CPU+GPU watercooled 280 rad pull only || whole-house loop.

Server Router (Untangle): 13600k @ Stock || ASRock Z690 ITX || All 10Gbe || 2x8GB 3200 || PicoPSU 150W 24pin + AX1200i on CPU|| whole-house loop

I wouldn't call it headroom for the future if Nvidia doesn't officially support it.

Why wouldn't Nvidia support 2000W PSU?

I think you got confused a bit, since I was talking about 2000W PSU.

Well you can get it to work though

Sure if your willing to jump through several hoops. Not worth the time IMO.

Oh wait lol I was thinking of the 3 card setup not the power supply. Sorry.

I like how everyone keeps trying to tell OP 3 way sli is a bad idea, as if he hasnt already figured out "hey its not 100% efficient" and cares about having diminishing returns. If the dude is baller enough to get nearly $3k in CPU and GPU, let the dude do what he wants. "It can be done and I want to do it" should be all he has to say.

 

1200w should be fine my dude, though I might consider 1600w just so that you're around half PSU load for better efficiency

If your a benchmarker then that I can understand.

Get the G2, I have the 1000 and it's a good power supply. 

 

I look forward to your "PC underperforming" topic. 

If anyone asks you never saw me.

So you can't be an enthusiast unless you have SLI?

Correct /jk

 

For real though: Most people who run an SLi setup are enthusiasts. Enthusiast PC's are also usually equipped with full watercooling, HEDT processors and multiple GPUs. Anything to get as much performance as possible.

CORRECT! To be part of the PCMR you need 4x Quadro P6000s in SLI (watercooled, obviously), and 3x 10tb SSDs to store your PCMR memes

 

And true, but there's also the kids that just find the most expensive components possible and slap them together to look cool, "Oh look at me I stole my mom's credit card". Like the one kid on here that made a build with an SLI Bridge, and only one card.
