NShi Server Chassis 250W Dual Output 5V 24V PFC

Compact Server Power Unit

This dual-output chassis supply delivers 5 V and 24 V rails from a single desktop enclosure. It suits integrators building embedded servers or test rigs that need isolated grounds for each channel. The active PFC circuit keeps the power factor above 0.92 across the universal input range. No internal fan means silent convection cooling in noise-sensitive racks.

Integration and Rail Management

The unit fits standard desktop chassis bays and provides independent isolated outputs with separate ground references for CH1 and CH2. Remote control is available on the 5 V channel for sequenced startup or standby management. Free-air convection removes the need for forced airflow paths in tight enclosures. Protections against short circuit, overload, over-voltage and over-temperature protect downstream boards.

Capacity Limits and Headroom

Continuous rating is 250 W with CH1 rated at 5 A and CH2 at 9.4 A. The 5 V rail can sustain a 170 % peak load for 10 seconds to handle spin-up transients. Full-load burn-in testing at 100 % validates thermal stability before deployment. Builders needing more than 250 W or additional voltage rails must look beyond this model.
