Power Win PW-150 150W AT Switching Power Supply w/ Power Switch Cable

Power Win PW-150 150W AT Switching Power Supply w/ Power Switch Cable

The Power Win PW-150 is a 150-watt AT-form-factor switching power supply designed for AT and baby-AT desktop computers. It delivers multiple regulated DC output rails — +5V, -5V, +12V, and -12V — through a multi-connector wire harness, and includes an inline power switch cable that connects to the PC's front-panel power button as required by the AT standard.

Applications

The AT power supply form factor predates ATX and was the standard in IBM-compatible desktop PCs from the early 1980s through the mid-1990s. AT supplies are distinguished by their two 6-pin motherboard power connectors (P8 and P9) and a hard-wired power switch circuit — unlike ATX supplies, which use a soft-switch standby system. The PW-150 is suited for maintaining or restoring AT-era desktop systems, including XT- and 286/386/486-class machines that require an AT-standard supply. These supplies remain in use today primarily for legacy system maintenance, retro computing, and industrial embedded systems that were built around AT-compatible boards and have not been updated to ATX infrastructure.
