An upgraded power supply will give you more juice for an accelerator. The stock A1200 power supply was only 21-watt so wasn't up to powering an accelerator with RAM + SCSI, then a hard disk etc.

You can convert a PC AT/ATX power supply for the Amiga as the voltages are the same. You'll need to keep your original square A1200 plug and get instructions as to the pin lauout.

The AT/ATX power supply conversion won't require soldering as you can simply use a connector block. However you will need to use a multimeter to verify the voltages on the wires.

This archive has a picture which shows the voltages required by the desktop Amigas:

It might be easier to just buy an Amiga tower like the Power Tower/Micronik or get a PC case so you will have a switch for the PSU. An external case will help for storing CD-ROM drives etc. but you can get heavy duty PSUs such as the Wizard Powerbox and Goliath Power Supply that are self contained, external boxes.

I blew two power supplies (one was a meatier A500 version) when I upgraded to Blizzard 1230-IV/SCSI-IV but this may have had something to do with a power hungry scandoubler/FF competing with an internal hard disk.

For artists there are Genius/Tabby graphics tablets (pen style mice).

For keeping power consumption and weight low maybe an internal ATA flash drive would help.
