Gpu not detected...

[_Platinum_]

So I just finished building my new pc and what do you know my gpu isnt even detected. It lights up and the fans spin for a bit on startup. Im getting a signal to my monitor but it doesnt detect my second monitor.
Its a MSI 1080ti trio, what could be the issue?

First and foremost make sure EVERY power cable is plugged in. You may have missed the CPU one and your computer will act like this. If you have other video cables to try, do that. Try different ports out too. Do you have onboard graphics or another gpu to test?

Well simple solutions first. You are plugging your display cables into the back of the GPU and not the motherboard correct? You plugged in all the necessary power cables from your power supply to the GPU?

The rest of your specs? Including PSU make and model.
