I had also some problems when I had the Indivision AGA MK3 in the begin.
Some errors like no hardware found, bad picture. This was with the original A1200 PSU.
Then I bought a PSU from a Polish company, did't have a problem for 1 week...
After 1 week again the same problems, and than on a day... that new PSU was blown up after using for about 20 minutes that day. End of life for that Polish PSU.
At last, I bought in August of this year the CA-PSU from Jens and now 4 months later, didn't have any problems so far.
It's maybe not the cheapest PSU on the market, but it's the best I ever used.
