I have 2 Rx480 and 1 Rx470
Working perfect with one card directly plugged into pcie x16 and 2 usb powered risers
Now I bought another Rx480 with usb riser
So my problem is with 4 cards plugged into Mother board PC (Win 10) does not boot...
Fans are spinning on all 4 cards
Anybody know why??
Maybe its because of PSU?
Its 750 Watt

I have to undervotlage my 4xRX480 4GB to run from a 1000W PSU. Really can't see how 750W would have a chance.
lol I run 8x RX470s from a 850 watt PSU
Why do not you tell people how much you reduce the clock speed graphics cards?
1150/1900 obviously custom bios undervolted etc. Still pulls 890 at the wall, but the point of my post is as long as you know how to balance rails and tune everything right there is no reason you can't run a PSU at its max capacity.
