I have a $60 Lenovo D30 1120w PSU that I've just installed in a Rosewill chassis; waiting on the install kit and some PCIe power expanders but the intent is to eventually house 7x 1060s plus a 2680v2. Once I confirm it's working I'll let you know.Also one windows 7 pc running my GTX 1060 p106 dedicated mining gpu's to test them, still need risers and decide on a power supply to run all 6 of the mining gpu's in my mining case.
