How much wattage for a 1080 or 1080ti

WhereHere1 · 16 Jul 2017 at 00:07

just wondering what other people would think.

Would 650 be enough for a 1080ti?

What about just a 1080?

650W will be plenty, providing it's a decent PSU. The 1080Ti is more efficient than a 980Ti. As long as your PSU is a decent model, it'll be fine.

I use a 1080 on a 520w.

I currently have a 450w, would that be pushing it?

What is the make and model of the PSU, also system specs.

High quality 450W PSU would be enough for non overclocked CPU and reference clock 1080.

GP102 chipped 1080 Ti again needs upwards 300W and for that 650W PSU would be quite approriate especially with high end CPU.
People have just gotten weird fixation that every Nvidia card is light on power consumption.

I've got that, running a i5 4690k at 4.1ghz and MSI 970 GTX pretty much overclocked as far as i can take it, im planning to upgrade to a 1080 or 1080ti soon to use my Acer 34a better and was going to upgrade the PSU and give the old one to my mrs new rig

lower power limit by 12% and you will be getting around 260w for a 1080ti with hardly any drop in performance.

a gtx 1080ti uses up to 200w max when not overclocked, that is under 100% load though, games genrally dont make 100% load. So mostly in games 150w will be the typical input for a GTX1080TI

You're mixing GP102 and GP104 chips.
"Medium" size GP104 equipped 1080 stays below 200W, except for some factory overclocked models.
Big GP102 chip 1080 Tis draw well past 250W (except for reference/Founders Edition) with some of them reaching towards 300W:

Well mine is a FE GTX 1080ti, so I only draw 200w at 100% load, if not overclocked.
