I got a new graphics card.
I installed Adrenalin drivers on Win 10.
OCCX shuts system off when the graphic card is stress tested (Right away).
I have 550 Watt power supply. 6+2 power cable. 12v 25A. (I also tested by adding in additional 10A with ATX green wire added and 12v power from another supply).
systemboard Gigabyte 78lmt USB3, with pcie 3.0 x16 slot.
OCCX doesnt help a non OCCX expert.
AMD has no application to test the card.
Amazon asked if I contacted the manufacturer before returning it.
