Thanks, Paul.
In the likelihood that I blow up my house by plugging it in, I'll come back here asking for shelter. 
Wouldn't hurt to wait for other people to confirm what I said. I don't want to be responsible for blowing up your A1200. But if it's like the PSU I have, then it's a good PSU and runs cool even under a heavy loaded Amiga. :pint:
Good luck!
