RTX 2080Ti SLI with Threadripper 2950x - Need help with SLI & PSU Wattage

Technically yes.

But I wouldn't go with sli 

Doesn't scale well in games and has almost no performance benifits 

Unless you use a software that does 

But in games, it's really not worth it.

Will this PSU wattage be sufficient for my SLI setup

More than enough.

No for the most part.

Hi folks,

 

My current PC parts are mentioned here: https://pcpartpicker.com/list/cvpyn7

 

I am trying to setup NVLink/SLI with RTX 2080ti and had the below doubts, would appreciate someone clarifying it out:

 

1) I have a Zotac GeForce RTX 2080 Ti Graphic card now and managed to grab INNO3D GEFORCE RTX 2080 TI TWIN X2 at a good deal, can I do a NvLink/SLI setup with these 2 GPU's?

 

Zotac has 1665 Boost clock and Inno3d with 1545 boost clock, I'm assuming I have to run them both at 1545 Mhz if its compatible for a SLI which is fine.

 

2) My CPU is Ryzen Threadripper 2950x. PC partmaker and few other websites are suggesting estimated wattage of around 750-800W. I currently am using Coolmaster V1000 80+ Gold certified: https://www.coolermaster.com/catalog/power-supplies/v-series/v1000/

 

Will this PSU wattage be sufficient for my SLI setup? I'm not planning to OC GPU but I am running OC on CPU with Auto PBO setting and RAM is OC'ed. I also do have 4x 140mm, 4x 120mm fans, a fan controller installed in my Corsair 500R case.

 

My current consumption goes to 600-650W at the max during high fps gaming. 

 

4) Will I shorten my PSU life if wattage hits 850-950W during gaming? Can a PSU run at 80-90% load a few hours daily and function for 2-5 years ?

 

5) My current UPS (APC BR1500G) is rated 1500 VA/865W:  https://www.amazon.com/APC-Back-UPS-Battery-Protector-BR1500G/dp/B003Y24DEU

Will this be able to supply power upto 1000W? I really don't use it for backup purposes, I wouldn't want it to shut off power to CPU if it exceeds 865W. If it lasts even a few seconds its fine for me to shutdown PC manually.

 

Thanks!

The UPS will be alright for the most part. I used one of those when I had a 2950X and dual 1080 Tis. It did overload if I was folding with both GPUs and the CPU, but was fine when I cut it down to just GPUs.

Thanks for your suggestions @TofuHaroto @Den-Fi.

 

@Den-Fi Does the UPS shutoff power to the CPU if it gets overloaded while its connected to current from wall? I really don't mind about backup purposes, I am worried about voltage fluctuations at my place and them not damaging my CPU.

I’d imagine if it was left like that it would. In the few times it happened to me, it sounded an alarm and I was able to stop it before anything happened.
