Desktop Server Chassis Power Supply

The NShi 750W unit delivers 24V at 31.3A for desktop server builds. It accepts a universal AC input range of 90 to 264VAC and operates up to 70°C with forced air cooling. High efficiency reaches 92% to reduce waste heat in dense installations. Built-in active PFC improves power quality for rack environments.

Programmable Output and Remote Control

Output voltage and constant current levels are programmable for flexible load matching. Remote ON-OFF control, remote sense, auxiliary power and a DC OK signal integrate directly with management systems. Protections cover short circuit, overload, over voltage and over temperature without extra hardware. Optional conformal coating adds resilience for harsh conditions.

Verify AC Input Range and Cooling Clearance

Confirm the site supply stays within 90 to 264VAC before installation. Ensure chassis airflow can handle forced air cooling at the rated 751.2W load. Check that remote sense and control wiring match your management controller pinouts. Buyers needing redundant hot-swap modules or a different DC voltage should look elsewhere.

Questions about this item

What maintenance will the built-in DC fan need?

The forced-air fan is the only moving part; dust it periodically to keep airflow clear.

What limit appears first under sustained full-load operation?

The unit is rated for continuous output up to 70 °C ambient; above that temperature protection will shut it down.

How much noise and heat should I expect when it runs all day?

At up to 92 % efficiency the waste heat is low, and the fan speed varies with temperature to stay as quiet as cooling allows.
