New Build Won't Start

I already tested my PSU with the tester that came with it and it worked. I plugged PSU to the case fans and they began to spin and light up. However, when I plugged in all of the necessary cables into the motherboard and turned on the PSU switch, the CPU cooler fan light would flash once but when I clicked the power button on the case nothing would happen.

I have tried putting both RAM sticks individually in every slot, and I have already made sure I plugged in fully each cable, I also tried to jump the Power SW with a screwdriver and reseat the CMOS battery. There isn't any physical damage to the CPU or any visible damage to the MOBO and its pins.

Is it possible that the PSU can still be faulty? This is also my second motherboard because the first one was DOA. I have been trying to figure out this issue for days but still can't find a solution.

Sounds like a short. Could be the PSU, unlikely it's two in a row with the same problem. Isolate as much as you can. Board, 1 stick of RAM on a piece of cardboard. 24 and 8 pin only. See what it does.
