installed a new psu thathas a 20 pin mootherboard connector, the one I took out had a 24 pin connector. I plugged the 20 pin connector into the motherboard leaving the remaining four pins empty. The computer powers up for a second and the fans come on but then it shuts down again. Is this because Im trying to hook up a 20 pin motherboard conector to a 24 pin

No...a 20-pin can work in a 24-pin plug (I did it for some time on a prior system).

But you need to connect properly.
