Hello everyone!

I'm writing this because DELL Support didnt have any experience or waranty support tested with Nvidia GTX consumer video cards.

Some weeks ago we purchased an EVGA Nvidia GTX 1080ti 11GB after several researching we didnt get help with Dell Support because they only have tested the QUADRO series of nvidia. So.... we did a lot of tryouts to get this video card work...

We have a 685W PSU with two 6-pin conectors free into the case. The GTX 1080ti needs for a 8-pin connector and a 6-pin conector to work... so we bought this adapter: 6-PIN to 8-PIN PCI ADAPTER. After that we tried this conection: a 6-pin conector to 8-pin using the adapter we bought. Then we didnt get any image on our monitor... 

So we thought that the power isnt was enough to feed the requirements of the Video Card... so we bought another bunch of cables including, SATA to 6-pin or SATA to Molex........ after serveral tryouts the final resolution was that our monitor it wasnt waking up with the signal, so we tried into another monitor and it worked so perfectly that we already tried our 3D apps and put the equipment under stress for hours just to know that works fine.

Final Result

You will need:

• Adapter. 6-PIN to 8-PIN PCI ADAPTER
• 685W or higher PSU (Power supply Unit)
• Another Monitor if your current monitor doesnt show any Signal
• This post to help you :)

Aplications Tested

• 3dsMax2018 with Corona Render
• Lumion 2018 (rendering stills and video with ultra settings) getting 80 celcius degrees of temperature during the stress work of rendering this images and videos.
• Archicad
• AutoCAD

Consider this in the future

• consider a well ventilated space, the case of this workstation (5810 Precision) doesnt have enought ventilation unless you use the space in the back of the case for a 7 or 8cms Fan (Maybe). Or consider using one face opened to the exterior and ventilate it from outside.
• monitor allways the temperature and use of the videocard.

Current Setup

• 1 HDD used of the 2 Free bays.
• Intel Xeon E5-1650 v3 @ 3.50Ghz.
• 32GB Ram
• CD / DVD Unit
• I removed the Nvidia Quadro K2200 that came from factory.

Hope it works well for you, this is my experience and im not responsable of any damage you can do to your system if you dont know how to handle this devices. For me just works fine and so good now.
