PSU Help

[alan101]

what is a good quality PSU? I want one that is 1,000watts that can handle two 1080ti's in SLI. I honestly haven't really shopped for these that much so any advice will help.

Corsair and EVGA have been my PSU brands of choice.  In that Wattage all the models they make are quality items with good warranties.

I would suggest choosing a PSU from the two top tiers in this list:

For me as well. I never use and never recommend any other brands.

 

@alan101 I would suggest the EVGA SuperNOVA 1000 G2, 80+ Gold 1000 W: https://www.evga.com/products/product.aspx?pn=120-g2-1000-xr

This may seem like a dumb question so sorry in advance but how can you tell how many GPU's a PSU will support?

There's two from the top tier list, the first is only semi modular but is an amazon's choice

Bottom if fully modular

I may be wrong on this, but i'm guessing any 1000W PSU worth it's salt will have enough spots for 2 gpus. Now if you're doing a 10 GPU mining rig, probably need to do some more research, but with just 2, you should be fine

Should a 1,000 watt power two 1080's TI and a 8700k CPU?

That will be more than enough

Yes.  All day long.  You could go lower.

This is a good tool to get a general idea of how much power you'll need.

Depending on the manufacturer, one 1080 Ti needs either one 8 pin and one 6 pin power connector or two 8 pin power connectors.

Therefore two 1080 Tis needs either two 8 pin and two 6 pin power connectors or four 8 pin power connectors.

 

Next, check the power consumtion of your card. A FE 1080 Ti at idle draws 13 W, but this can increase rapidly with more demanding tasks: https://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-ti,4972-6.html

 

So, verify the amount of connectors available on your PSU and also the amount of current each rail of your PSU can provide.

mine are both 6pins plus 8 pins each
