Protected switched-mode replacement supplies for the C64 and round-connector VIC-20CR, with separate adapters for the C128 and Plus/4.

On 2026-07-30, Commodore4ever listed the original ATOM and ATOM v2.5 at USD 59.99 and ATOM RETRO at USD 69.99; all three were sold out. The official Plus/4 adapter was also sold out at USD 24.99. A separate live 90-degree adapter page listed a 64-to-128 option at USD 14.99, but did not expose unambiguous variant stock or identify every supported ATOM revision. The original ATOM page lists separate North American 120 VAC and European 230 VAC configurations, ATOM v2.5 lists only the North American input, and ATOM RETRO says its European version is currently unavailable. Surviving pages provide too little detail to establish exact specifications or final availability for the older PS-64 with LED and PS-64/128. Do not assume that ATOM specifications apply to those predecessor models.

DiscontinuedChecked Jul 30, 2026saV64 Overvoltage Protectorby Heather (SkydivinGirl) and e5frog
overvoltage protectionrelaypower cutoffreset buttonstatus ledc64vic 20crplus 4 adaptervintage

A historical relay protector with alternate DC and AC inputs for several Commodore power configurations.

The surviving Round 4 sale thread is explicitly titled SOLD and dates to 2017. It offered complete kits at USD 45 and assembled units at USD 85. C64 OS repeated those prices in 2022, but that does not establish later production. The former hookturn.com user-guide URL now resolves to a parked domain. Use the preserved feature and forum specifications for identification, and search the used market rather than contacting the old seller as though stock were current.
