Nvlink 2080 ti watt

I'd go for the upgrade too but it'll probably be just about enough to run stock, assuming it is a good quality PSU and depending on the rest of the system. I used to run 2x980Ti and a 6700k off a 650W, with not a lot of headroom...

At least 850W but if you are spending close to $3000 on Gpu's just get an EVGA SuperNOVA 1000W/1200W.  They are 80+ platinum, fully modular and cost around $150-$180.  You can find them used for cheaper (I got my 1200 for $80)

They draw about 250W each under load, maybe up to 300W with unlocked power limits and OCing. What CPU are you using?

Which 750W PSU is it?

What kind of a PSU should one have to run 2 2080 ti's in Nvlink? i currently have a 750w so i was wondering if that is enough or should i get one with more watts.

It's not enough, it'll depend on the rest of your system but you'll probably be looking at least on 850w.


My system as is consumes about 580w~600w on peak loads and my TX650M is pretty much being fully utilized on full system stress, I doubt extra 100w would suffice for a whole extra card, if you're going HEDT then it won't be enough for sure.

850w if you have those gpus and a mainstream cpu so anything on X370,X470,Z370,Z390 but if you have HEDT (high end desktop) or more like X299,X399 then you might want to step it up. what cpu do you have. or just punch in you specs in pcpartpicker.com and see what it thinks you should then add 50w to its recommendation
