Quad-output power supply delivers 3.3 V, 5 V, and ±12 V rails totalling 204 W with active PFC and forced-air cooling
The NShi QP-200-3B is a desktop server chassis that integrates a Mean Well quad-output power supply. It delivers 3.3 V at .7 A, 5 V at 6 A, +12 V at 15 A and -12 V at .7 A for a total of 204 W. The unit suits builders who need multiple regulated rails in a compact desktop enclosure.
Universal AC input with built-in active PFC allows the chassis to connect directly to mains power worldwide without a separate adapter. Forced air cooling from the internal DC fan handles 200 W loads, while free-air convection covers lighter 75 W to 100 W workloads. Over-temperature protection triggers between 200 W and 320 W to protect internal components.
The 204 W maximum output limits use in configurations that demand more power or extra voltage rails. Short-circuit, overload and over-voltage protections safeguard connected hardware during normal operation. The chassis does not address requirements for redundant supplies or hot-swap bays.

The built-in over-temperature protection activates between 200W and 320W, with optional settings for 100W and 150W thresholds.
Forced air cooling by the built-in DC fan engages at 150W, 200W and 320W levels; below 100W it uses free air convection.
Universal AC input with full range coverage handles worldwide mains voltages without manual switching.
