Radius Inc 915-0100R 15RAF5 Macintosh Power Supply Vintage Apple Mac
The Radius Inc 915-0100R is an internal open-frame power supply unit manufactured for vintage Apple Macintosh computers. Radius Inc was a third-party hardware manufacturer active in the 1980s and 1990s that produced monitors, accelerator cards, and supporting hardware for the Apple Macintosh platform. This PSU (model 15RAF5, lot/serial Z018NH0155TJ2) follows the open-frame switching power supply design typical of Macintosh-era internal supplies, with a sheet-metal chassis, a switching PCB, and a bundled output harness with proprietary and Molex-style connectors. It is being sold AS-IS due to its age and has not been tested.

Applications
Radius Inc was one of the most prominent third-party accessory makers for the classic Macintosh platform during the late 1980s and early 1990s, producing products designed to extend and enhance Apple's closed hardware ecosystem. Internal power supplies of this type were used within Macintosh desktop enclosures to convert AC mains power into the DC voltages required by the logic board, drives, and peripheral cards. Today, units like this are sought by vintage Mac enthusiasts, collectors, and repair technicians restoring classic Macintosh systems to working order. A functioning replacement PSU is often the key part needed to revive an otherwise complete vintage Mac, making even as-is units valuable for parts harvesting or bench repair work.
This Radius Inc 915-0100R (15RAF5) Macintosh power supply is being sold AS-IS due to its age. We have not tested or powered this unit, and it is not guaranteed functional. It appears cosmetically intact — the metal chassis is present with no obvious physical damage, the PCB shows no visible burned components or catastrophic damage, and the output wire harness with its connectors is attached and intact. That said, given its vintage age, buyers should purchase for parts, restoration, or repair purposes. Please review our photo set carefully and contact us with any questions before purchasing.
