Power Supply for Server Builds

The NShi SP-320-15 is an AC-to-DC power supply built for server chassis installations. It delivers a single 15 Volt output at 20 Amps for a total of 300 Watts. The unit measures 8.5 inches long by 4.5 inches wide by 2.0 inches high in a silver finish.

Replacing Older Linear Units

This auto-switching supply replaces bulky linear units and older switchers that lack wide-range input. The jump is worth it when you need 86 percent efficiency to cut heat and noise in a compact desktop chassis. It fits the same footprint while providing cleaner power for sensitive server boards.

300 Watt Continuous Capacity

The 300 Watt rating handles typical single-board servers, storage controllers and expansion cards with headroom for startup surges. It runs out when total draw exceeds 20 Amps on the 15 Volt rail or when multiple high-draw GPUs are added. Builders needing more than 300 Watts must specify a larger unit.

Questions about this item

Will the 8.5 by 4.5 inch footprint fit my desktop server chassis?

The supply measures 8.5 inches long by 4.5 inches wide by 2.0 inches high, so verify your chassis bay matches those dimensions before ordering.

How do I wire the auto-switching input, and what mistake should I avoid?

Connect the AC mains to the three-pin input; the unit auto-switches between voltages, but do not reverse the live and neutral conductors.

When will the 15 volt 20 amp output need attention?

With 86 percent efficiency the unit runs warm; keep the ventilation slots clear and replace the supply if the output drifts from 15 volts under a 20 amp load.
