Desktop server chassis with integrated 500 W industrial power supply delivering DC outputs at 5 V, 12 V, 24 V and 36 V
This desktop server chassis integrates a 500W industrial-grade SMPS that converts 110V or 240V AC input into regulated 5V, 12V, 24V and 36V DC rails. It is built for engineers and system integrators who need a compact, metal-cased power source for test benches, automation rigs or embedded deployments. Buyers requiring ATX-form-factor cables or redundant hot-swap modules should look elsewhere.
The aluminium-and-steel enclosure operates from 0°C to 40°C with passive airflow, so acoustic output stays at a low hum under typical loads. Built-in over-voltage, over-current and short-circuit protection clamps faults before they stress connected hardware. Efficiency is rated for continuous operation up to the full 500W rating without thermal throttling.
The unit ships with CCC, RoHS and CE compliance markings already applied, removing the need for separate certification paperwork in most jurisdictions. Integrated protection circuits — over-voltage, over-current and short-circuit — replace external fuse boards and simplify wiring looms. No configuration software or monitoring utilities are included or required.

Secure the metal case with its mounting holes, connect live, neutral and earth to the AC terminals, then verify the input selector matches your 110V or 240V mains before powering on.
Internal electrolytic capacitors and the cooling fan are the components that typically age first under continuous 0 to 40°C operation.
The unit is rated for up to 60A total output; the built-in over-current circuit activates when any rail exceeds its share of that 500W limit.
