48 V 500 W server power supply

The NShi RSP-500-48 is a 500 W enclosed AC/DC unit delivering a fixed 48 V output. It is built for rack or desktop servers that require a single high-current rail. The supply accepts 85–264 VAC input and carries CE, FCC and RoHS certification. It suits integrators who need a compact, safety-approved power source.

Fits standard desktop server chassis

The module mounts in a desktop-form-factor chassis and connects directly to the system backplane or motherboard power connectors. Built-in remote ON-OFF control, remote sense and a DC OK signal simplify wiring and monitoring. No external fan assembly is required because cooling is handled internally. The 1.3 kg weight adds minimal load to the chassis structure.

Fan speed control up to 70 °C

An internal fan with automatic speed control maintains temperatures from -10 °C to 70 °C ambient. Humidity tolerance spans 0–95 % non-condensing. Total power consumption reaches 504 W under full load. The supply is not suited for builds that need redundant or hot-swap power modules.

Questions about this item

What input voltage range does the RSP-500-48 accept for continuous operation?

The unit operates from 85 to 264 VAC at 65 Hz, covering most mains supplies worldwide.

How hot does the chassis get when the supply runs at full load all day?

The built-in fan with speed control keeps the supply within its rated -10 °C to 70 °C ambient range during sustained use.

Which connectors must already be in place for the DC output to be used?

The 48 V output uses screw terminals, so suitable cables and crimped lugs are needed to complete the circuit.
