Here's my build based on one of Phil's 3 card builds. I added 1 riser for a 4 card rig. Added risers to a shelf to mount the motherboard and riser. Also made a custom card holder and fan mount from extra shelf parts. Pulling 2450 Sol/s at 755w at the wall. Very stable rig.
3 x MSI Aero 1080 ti
1 x MSI Aero 1070 Mini
1 x EVGA G3 850
1 X 4GB Ram
1 x 32 GB Lexar USB running Fullzero's nvOC
good I am glad I inspired you to do it.
I get 6,7,8,9,10,11,12,and even 13 card beast..
but these 3,4 card builds using a evga 850 watt psu or a rosewill quark 850 watt psu are dead solid builds.
I have a different mobo to test a gigabyte ga-b250-hd3
I did a win 10 build and it was a disaster some weird eth card issue/ I did a win 7 and the het card worked I updated it to win 10 and got around the direct win 10 build eth card fail this time I will do a nvoc build using a higher end lexar usb stick
