I recently purchased a 1080 Ti FE and decided that I want to go SLI in the near future. However, my current PSU is very limited (700W I believe). With a lot of money invested into my machine, I want to back up my components with a solid PSU that is future-proof. What PSU should I look into for 1080 Ti SLI and future SLI? Is 1000W enough or should I go for 1200W? This is my current rig:

Case: Zalman Z9 Neo White Mid Tower (https://www.amazon.com/Zalman-Performance-Gaming-Tower-White/dp/B01A3N75GU/ref=sr_1_1?ie=UTF8&qid=1491372063&sr=8-1&keywords=zalman+z9+neo+white)

Motherboard: Asus X-99A/USB 3.1 (https://www.amazon.com/ASUS-USB-3-1-Intel-Motherboards/dp/B00VUK55M2/ref=sr_1_1?ie=UTF8&qid=1491372109&sr=8-1&keywords=asus+x-99A)

CPU: i7-5820k @ 3.3 Ghz (factory clock). I plan on OC'ing this CPU once I upgrade to a water cooling unit.

CPU Cooler: SilenX EFZ-120 (https://www.amazon.com/Silenx-Effizio-120mm-Intel-Heatsink/dp/B007VQO7GE/ref=sr_1_1?ie=UTF8&qid=1491372406&sr=8-1&keywords=SilenX+EFZ-120)

RAM: 16GB DDR4 2400 (2x8)

Storage: PNY 240GB SSD, 1TB 7400RPM HDD, 3TB 5400RPM HDD

Hard drive: Asus 16x BDRW SATA Internal Blu-Ray

Video Card: GTX 1080 Ti FE (overclocked +150 Core, +500 Memory)

Monitors: Samsung u28E590 28 inch 3840x2160 (https://www.amazon.com/Samsung-U28E590D-28-Inch-LED-Lit-Freesync/dp/B00YD3DBOC/ref=sr_1_1?s=electronics&ie=UTF8&qid=1491372781&sr=1-1&keywords=samsung+28+4k) and Acer XG270HU 2560x1440p 144hz (https://www.amazon.com/gp/product/B00VRCLHYS/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)

I'm currently eyeing this PSU: https://www.amazon.com/EVGA-SuperNOVA-TITANIUM-Warranty-220-T2-1000-X1/dp/B018JYHGQE/ref=sr_1_2?ie=UTF8&qid=1491372519&sr=8-2&keywords=PSU+titanium

But I don't know if 1000W will be enough for 1080 Ti SLI and future SLI.

Bronze is the 80Plus certification badge on the unit which actually tells squat about the quality of the PSU in this day and age. Get back to us when you have access to your system and the make+model of your PSU.

This post had everything posted except the make and model of your PSU. Going along with only wattage then there would've been some really awesome builds with 50USD 700W's. jokes aside, please include the make and model of your current 700W unit. Per your dual GTX1080Ti setup, you're going to need 850W but that doesn't mean you can skip out on quality/brands. You should look through this tier list and pick out a unit that is as close to Tier 1 as possible for the sake of reliability. Add more wattage than 850W's for headroom.

FYI, Nvidia have already stated that SLI support will come solely from the game developers, if the game doesn't support it then you're just drawing power and not producing more FPS.

The PSU you've listed is top tier, worth it IMHO.

I don't remember the exact model or quality of my current PSU. My friend, who put together this PC for me last year, selected some of the components. The PSU isn't on the original receipt, so I wasn't charged for it. Good news for my wallet, but bad news for my rig because I don't know the brand of the PSU. I haven't had the chance to open up my rig, but I'm going to have to do so soon. All I remember was the wattage (700), and the quality was probably Bronze lol. :(
