If memory serves me correctly, you need a resistive load across the 
voltage outputs, otherwise the PSU will behave like that. They do make 
test plugs or at least used to for PSUs that provide the load needed to 
turn on. If it does the same thing with the plug then it's the PSU. Also 
I think that HDDs do provide enough load to trigger the PSU to stay on. 
Did you have any hdds, optical drives still plugged in? It's possible 
that one of them is dragging down the PSU.
