I have a new Z390 Ace+ Intel 9700K + GeForce 1660 (1667-kr7) + 850 W PSU. Equipment i sconnected OUTSIDE the cabinet for pre-test.
When I turn on the PSU, the mobo "power" button lights up. When I press it, the GPU & cooler fans spin, RGB RAM lights up and mobo error LEDS indicate 00. But there is NOTHING on my DVI connected monitor (which was working on another system). The DVI cable is brand new, as are al the other parts. When I press the monitor "menu" button, it says it is in power-saving mode.
I have triple checked all connectors for tight connection.
ONE worrisome point: the GPU wobbles side to side in the PCI-e slot (closest to the CPU), although I have pressed it secretly into position. And yes, I have connected the 6+2 pin cable (8 on one end into the PSU, 6+2 on the other end with all 8 plugged in).
I would appreciate any suggestions for testing/fixing this problem.
Live long and prosper and thanks for all the help!
