3.3 V 60 A Power Supply for Server Chassis
The NShi SP-320-3.3 is a single-output AC/DC unit delivering 3.3 V at 60 A for 181.5 W total power. It fits desktop-type server chassis builds that require a dedicated 3.3 V rail. The supply accepts universal AC input across the full range and includes active PFC. It is built for continuous operation in rack or tower environments.
Thermals Noise and Power Draw
Forced air cooling is provided by a built-in DC fan with integrated speed control. The unit has passed a 100 % full-load burn-in test at rated output. Protections cover short circuit, overload, over voltage and over temperature conditions. Active PFC helps maintain efficient power factor across the input range.
Bundled Signals and Parallel Operation
The supply includes a DC OK signal output and supports remote sense plus ON/OFF control. Current sharing allows up to 2400 W in a 3+1 parallel configuration using compatible PSP-600 units. PG and PF signal outputs are available on related SP-750 models. These features simplify monitoring and redundancy in multi-unit deployments.

Questions about this item
How do I mount this desktop chassis and connect the 9-pin output without reversing the 3.3 V and ground pins?
Secure the unit with its four mounting holes, then plug the 9-pin connector so the three 3.3 V pins and three ground pins match the motherboard header; the keyed shroud prevents a reversed fit.
Which part will need replacement first when the unit runs continuously at 60 A?
The built-in DC fan with speed control is the only moving component; its bearings wear before the solid-state circuitry, so plan a fan swap after several years of 24/7 operation.
At what sustained load does the over-temperature protection engage on this 181.5 W supply?
The protection triggers when internal temperature exceeds the design limit during prolonged full-load output of 181.5 W, especially if inlet air is restricted or ambient temperature is high.
