These photos are samples of the power supplies I [Ray Carson] make, which range from very simple "wall wart" designs that power a C64 only, to elaborate units that can power several devices at the same time.

Note that multiple–output power supplies are the most cost effective. For example, one PS can be built to power an Amiga, the C64 and C128, one or more 1581/1541–II drives, the Plus/4, C16, RAMLink, etc. or any combination of the above. More elaborate (and expensive) designs will allow many devices to run at the same time. The user should decide what will work best for them so a PS can be designed to closely meet those needs and note waste money on unnecessary options.

A standard C64/128 PS will have a single 5 foot (1.5 meter) power cable with two connectors on the end in a Y configuration. Fewer cables mean less clutter on the desktop but if separate cables or a single cable with adapter(s) is preferred, that's easy to implement, and longer cables can be installed if desired.

A standard AC power cord is used on 120V power supplies for the USA and Canada, and an IEC socket (same as a printer or monitor) is installed on the 230V supplies for Europe and Australia so the user can get the appropriate AC cord locally that fits their mains.

A power switch is installed on all supplies for the Amiga since there are none on those computers. The C64/128 and other 8 bit computer series have power switches so a power switch is not normally provided on the PS, but it can be if desired.
