--> Check the power switch 2 pin was in the right place

try testing the PSU short the green pin (I think) to a black one and see if it turns on.

Inspect the back of the motherboard and see if the cooler's backplate is grounding out somewhere. If it is, use some electrical tape to insulate the backplate.

Make sure your mobo isnt making any ki8nd of contact.

Try disconnecting everything other than the mobo and boot her up.

Correct. On the 24 pin power connector, there is a green wire (used to tell the PSU it is plugged nto a motherboard). If you get a paper clip and connect it to ground (any of the black wires), you are giving it a ground like it is connected to a board. Please unplug the PSU from power when connecting the paper clip!

This is a trick used to run the pump when watercooling. it allows you to run the water through the loop without having the CPU running.

Try pushing the AC PSU cable into the PSU harder?

Sounds stupid, but I had that problem once.
