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.
try to plug hdmi in differents ones ?
Im underclocking and undervolting so I wont have more than 550 Watts at the Wall with 4 cards.
But maybe PSU checks before booting and says 4 cards are too much? Is that possible?
