Description
SourceTek IPS-135U 135W Switching Power Supply 115/230V +5V 15A +12V 3.5A
The SourceTek IPS-135U is a 135-watt switching power supply in a compact steel enclosure, designed to deliver multiple regulated DC output voltages from a 115V or 230V AC source. It features an integrated cooling fan and a prominent external rocker-style ON/OFF switch mounted to the right side panel. The unit uses a multi-rail output design with a Molex connector wiring harness, consistent with legacy AT-era desktop and industrial computer applications.

Applications
The IPS-135U is a multi-output AT-style switching power supply of the type widely used in older IBM PC-compatible desktop computers and industrial embedded systems from the late 1980s through the 1990s. The AT power supply form factor preceded the modern ATX standard and was common in systems built around 286, 386, and 486-era processors. These units are still sought for maintaining and repairing legacy industrial computers, CNC controllers, embedded systems, and vintage desktop systems that rely on the AT pinout and physical form factor. The dual-voltage AC input (115/230V) also made this style of supply suitable for international deployments and light industrial use cases requiring stable multi-rail DC power.
This SourceTek IPS-135U 135W switching power supply has been bench-tested at our facility and is in good working condition. The metal enclosure shows light surface wear and minor scuffing consistent with prior use. All output connectors on the wiring harness are present and intact. The external ON/OFF rocker switch is included and functional. Please view our photo set and contact us if you have any questions.
