four 1080 ti's could be 300 watts each if they are aorus
so 1200 x .85 = 1020 watts so if you have a 1000 watt psu it may not cut it
1200w/1300w to be safe
4 x Gigabyte Aorus
160core/100mem/PL=195@3000sols@870-900watts
MSI-Z270A-Pro, 4gb RAM, i3-7100, EVGA-G2-1600w
nvOC NVIDIA Linux
That's a beast of a PSU

Was looking to change my setup to 4 1080ti's and was curious about what PSU is out there to do it with....guess I know now.
Newegg is showing it at around $360 out of stock, some others have it higher. Is this purely for density sake? Wouldn't it be economically better to just make another rig for 2 cards and save on the PSU by using a 850W or so?
