EVGA GeForce GTX 1080 Ti FTW3 HYBRID Installation

[Mihatsu]

Hi,

I tried to find some info from here how to power (Mac Pro 4.1-5.1) 1080ti card where is 2x8-pin connector but here wasn't so many conversation about it. So I took risk and ordered EVGA GeForce GTX 1080 Ti FTW3 HYBRID card which is water cooled card. I was thinking to share this if it helps some one else. So I was thinking to power card by 2x6pin->8pin + 2xsata->8pin. Backup was 4xsata->8pin. I don't need DVD so I removed the DVD module and used power cables from there. Water cooling block fitted perfectly in front wall and even Mac hole spacing was same than in water block. Two screws are not so beautiful but I can live with it. I removed Mac original GPU fan because it was blowing to wrong direction and was useless. That's it, I did some test runs and card works perfectly. I use it mainly in Houdini & Redshift and Realflow fluid simulations and looks that it doesn't need extra power.

Here are some pictures from setup.

Hi,

I didn't use any special power modifications. I have two power cables:

https://www.amazon.com/gp/product/B077QX9CP1 This comes from motherboard
https://www.amazon.com/gp/product/B007Y8FSMQ This comes from DVD power cables

Actually the most difficult part was feed the power cable in DVD module area. You cannot route cables outside because then you cannot close the cover. There is small hole close the DVD doors, i was able to push connectors in from there (see picture).

I updated second EVGA GeForce GTX 1080 Ti FTW3 HYBRID, i was able to fit both radiators in the housing but cooling wasn't so nice. Both cards reached ~60c during rendering so i made radical decisions and made a huge hole in side panel. Now the radiators are sticking out, not so beautiful solution but now both cards are ~43c during the rendering.

Nice setup. What applications are you using tbese two cards for?

i'm using mainly Houdini + Redsihift. I have Windows 10 installed because old Nvidia drivers not support new denoising features anymore.
