I have the EVGA PSU he linked, and it is excellent.  It would be enough for your system if you are definitely not going to overclock it.  My rig has a 7820x and single 2080ti, both overclocked, and I have seen it pull 740w+...add another 2080ti and I would be seeing ~1100w.  Too close for the 1200w psu in my opinion.  If I were you, I would just get an EVGA 1600w and never have to worry about it.

Just started up The Division, took a screenshot at a peak wattage. This was in the base so not many things moving around, and I was running forward to make the wattage go up, but this will pretty much be peak.

I see you went with the 1200 watt PSU as well.

Had a 1000W but I don't want to use 95% of it all the time, I want some leftover wattage left, just in case.

Always a good plan.  you never know when you will need to stretch that extra little bit.

Had a good deal, sold my 1000W after 4 years of excellent service (RM1000) for almost same price I bought it for, and bought 1 month old HX1200 for £120 I think.

A RTX 2080 ti has about the same power consumption as a GTX 1080 ti so a 850 watt PSU would be fine with SLI and no overclock.

It will be cutting is short, but yes. If you don't OC 9900k or RTX's then it should be ok.

Straightforward question. 

 

Power usage for following system?

 

2080 TI (stock/no overclock)

2080 TI (stock/no overclock)

9900K (stock/no overclock)

32GB DDR4 3200Hz RGB Ram 

960GB Corsair m2 NVME

Z390 Asrock Taichi

6x RGB case fans

360MM Astek AIO in push/pull w/6 RGB fans

Lian li pc011 (room for 2x PSU if necessary)

 

Use case: 4K gaming only. Nothing else.

Purpose: Prevent dipping below 60Hz/FPS

 

I ordered a system with single 2080TI and Corsair RM850 PSU. Then found a too-good to passup deal on another 2080TI. 

 

Is this PSU gonna be able to push everything at stock settings?

 

Legit Reviews website did an SLI test on 2080 TIs and their whole system purportedly only pulled 640W in SLI, albeit with an 8086K rather than 9900K and various other different components. I find that value extremely low, but if even remotely accurate this 850W PSU should suffice, no?

 

Numerous other threads around the Internet have values all over the place for 2080TI SLI even here. Everything from 800W-1600W. 

 

I don't plan on overclocking as it doesnt seem to provide any benefit for 4K gaming. It was only in retrospect I realized 3200Hz ram was also not necessary for 4K gaming, but hindsight is 20/20 I guess and anyway it will help with regular browsing and whatever ancillary programs I find myself running. The point of the build was to both run games at 4K without ever dropping helow 60FPS, and to futureproof as much as possible. My last computer related purchase was an I5 2500K bought in 2011 and I hope to get similar lifetime out of this one. 

 

So all that irrelevant information being said, is the 850W gonna be enough,to push this computer in stock configuration?

 

Dont be too dissapointed when SLI causes edvery game to crash and works in 1-2/10 of the ones you play, and even then, not even double performance

Well, I'm using

I9 9900K OCed

4x8GB ram OCed

2 GTX 1080 TI OC edition with 120% power limit and 100 Mhz OC.

1 14 TB HDD

1 Optane Memory

1 950 Pro

1 1 TB HDD

6 case fan for water cooling

1 3.2W DDC pump for my custom water loop

 

When playing shadow of tomb raider the GPU usage is 100% for both GPUs and around 40% CPU usage. The average power usage is less than 700W (I'm using a TP Link outlet with build in power meter that I can see in the App, I'm not sure how accurate they are). I would say 1200W is enough. I have a 1600W Platinum tho.

Don't be too disappointed when you have no idea what you are talking about and doesn't crash even in the surprisingly few  AAA games it does nothing in, most of which are easy enough to drive that it doesn't matter anyways.

 

Anyways on-topic. I've been running a 5820k+2 980ti's all super overclocked (the system should draw more power than OP's in every task) for 4? years now on a 850W PSU. I've never had issues while gaming with overpower draw or anything like that. I did hit overpower protection once while trying to mine with my GPUs and CPU simultaneously, but I've never seen more than 750W in a game.

 

I would indeed recommend a 1kw PSU, but I can confirm survival is possible on 850W without much issue.

The P2 1200W? I recommend not getting it. A single rail 1200W PSU is just silly. If you get a high wattage PSU, make sure it supports multi rail. The P2 also has complaints about not being particularly quiet. 

Check out the RMi, HXi and Dark Power Pro 11.

Will just disable it, no biggie

Too late..picked up a used one yesterday. Didn't see your post in time. Oh well, was a fair price at least. And the TX850M it'll be replacing also seems to be single rail so meh. Maybe I'll luck out and it will turn out to be broken. 

 

Good to hear people with similar configs are pulling under 800W. Feel more comfortable now keeping TX as a backup
