NShi QP-150-3B Quad Output Server Chassis 150W

Compact quad-output server power supply

The NShi QP-150-3B is a 150 W desktop chassis power supply delivering four regulated rails: 3.3 V, 5 V, 12 V and -12 V. It suits builders assembling compact servers or industrial PCs that require multiple low-voltage outputs from a single unit. Active PFC and universal AC input simplify deployment across different mains voltages.

Thermals noise and power draw

Forced air cooling is handled by a built-in DC fan rated for 150 W, 200 W or 320 W configurations. Over-temperature protection triggers between 200 W and 320 W depending on the selected option. The active PFC function helps maintain efficient power factor across the full input range during normal operation.

Upgrade path and fit

This unit replaces older single-rail or dual-rail supplies where a quad-output design with -12 V is now required. The jump is worth it when a project needs simultaneous 3.3 V, 5 V, 12 V and -12 V rails with active PFC in a desktop form factor. It does not suit builds needing higher total wattage or additional PCIe connectors.
