Hi, is it possible that my GTX 1080 TI works only in BIOS due to weak power supply? I do have an older Corsair 750 W PSU that only has 6+2 plugs (no 8 pins). But if I plug two 6+2 plugs into the GPU , I can only boot into BIOS, after the POST messages, the PC stops to continue and the monitor switches off due to no signal...
Hi there, could you please specify the model of your Corsair PSU? All modern PSUs have a slot with 8 pins -> 6+2 pins as terminal cables so you shouldn't worry about that. High efficiency PSUs have also a 8 pins -> 2*(6+2) pins ( and the 6+2 pins terminal merged with the main 6+2 pins terminal is called bridge connector).
Here's an example of 8 pins -> 6+2 pins:
That configuration of the pins is a must to ensure complete compatibility within all graphic cards around.
To help you troubleshooting your problem, could you please list all the components of your computer? All I can tell you in advance is try to unplug completely your GPU (from PSU and from motherboard slot) and try to boot the system without it, and see what happens.
By the way next time I suggest you to open a new thread.
Best Regards
