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.

The Tindie page listed PowerUP! 64W PRO V2 at USD 29 on 2026-07-30, but ordering was paused while the seller takes a break through July 31, 2026. Confirm that sales have resumed and that the seller will ship to the destination. The current V2 listing says it is delivered at 5.15 V; the linked Version 1.0 manual instead documents a 5.2 V default and 5.05-5.25 V adjustment range, so follow the instructions supplied with the purchased hardware rather than assuming the older manual's calibration value.
