Hello,
For my A1200 with an Apollo 1230/40Mhz accelerator (with a 2.5''HD, an Ethernet card on PCMCIA and a Twister1200 serial card on the clock port), I use a standard A500 PSU and it works fine. If I had to upgrade to a 68040 or 68060, I would go for a PC PSU because the A500 would not do the job.
