Few possibles, Although PSU is powerful enough it could still be faulty in some way.
Faulty RAM can also cause such a problem, should also be checked.
BIOS setting so only PCIe is set as primary or only video output.
GPU drivers reinstalled or updated.
Check your power saving plan, it may be turning video off.

My psu is very much new...i was using an old 550 from corsair...
I performed a memory check... nothing is wrong with that
I updated my drivers
I checked my power plan
Everything is normal
