 One of the solutions is put an AT or ATX (pc units) PSU inside the original A2000 PSU's case.

 The pinouts you can find in:

  Amiga 2000 power supply (http://pinouts.ru/Power/amiga2000power_pinout.shtml)

and

 AT power supply (http://pinouts.ru/Power/MotherboardPower_pinout.shtml)

 or

ATX power supply (http://pinouts.ru/Power/atxpower_pinout.shtml)

 The only missing wire on those "substitutes" is the "thick" signal, who can be generated by the motherboard itself. Simply change the position of jumper J300 on the MB.

 If you have enough skills, you can make a thick generator (http://aminet.net/docs/hard/Mix_and_Tick.lha) yourself, so no problems with timing issues (when changing the video to NTSC or PAL).
