Hallo MichaƂ,

I also hobby a lot with old PCs with AT-style power connectors. 
These can be swapped. When testing boards and not paying enough 
attention, I did swap them. The result, depending on the the PSU: in 
some case nothing at all happened but most of the time the PSU made 
this high pitch sound. And then I knew I either hadn't been carefull 
enough with placing the connectors or some condensors on the board 
were making trouble. In 99% of the cases this were original IBM 
boards. I then connected an heavy duty PSU and simply waited until 
the faulty condensor(s) went PUFFFF :) Remark: do this outside your 
house because of the smell!

Remark: see it as a positive sign that your PSU is still making 

Kind regards / Met vriendelijke groet, Ruud Baltissen
