You're a bit light on PSU....
220w x 4 = 880W without CPU, Mobo & Ram...
Try 3 cards and not 4 and see where it gets you!
I actually have another 850w PSU. My plan was to connect 3GPU + mobo on one psu and 4 GPU's on the second psu.
I tried with just 3 (switching the Asus and EVGA) but can't get it to work unless I put one of those cards directly on the mobo.

Have you checked your farm settings?
One such power supply unit of 850 watts is enough for the operation of 3 view cards 3070
It is advisable to have any hard drive or SSD for testing video cards on the Windows operating system.
