Not sure if I have problem with PSU or motherboard

Putting my first build together and noticed that after connecting everything, and checking it twice, once I try to press the power button, nothing seems to turn on. The fan in the PSU seems to spin, but for a second before it stops. I also tried the paper clip trick on the PSU, and it seems to only spin after widgeting it, but it doesn't spin consistently at all. I also had trouble connecting the 24 pin connector of the PSU into the motherboard (it wouldn't latch on). So I'm not sure which could be the real problem and not sure if I can fix it myself or if I should return them before it is too late.
