If you are certain that your memory isn't on the list, it could well be the cause of the problem.
Do you have any other DDR4 on hand to try out?
But before you go out and return the memory and buy a new kit, simply make sure that all the power connectors are properly in. (CPU, MB, GPU, Ram seated correctly, try out the other ram slots (2 and 4), try only a single stick.)
Your power supply should be fine, if it is a newer model, but could cause problems if it was a junk psu picked up used.
