NShi HRPG-600-3.3 3.3V 120A 396W Server Chassis

3.3 V 396 W Server Power Supply

The NShi HRPG-600-3.3 is a desktop-type server chassis power supply delivering a single 3.3 V output at 120 A for 396 W total power. It includes active power factor correction and a constant current limiting circuit for stable operation. A built-in DC fan provides forced air cooling across the unit. The supply has passed a 100 percent full load burn-in test.

Build Integration and Clearances

Universal AC input with full range support allows connection to mains worldwide without voltage selection. The unit withstands a 300 VAC surge input for five seconds, protecting against transient spikes. Remote sense and remote ON/OFF control terminals enable precise voltage regulation and system-level power sequencing. A 5 V 0.3 A standby output and DC OK signal simplify supervisory circuitry.

Suitable Deployments and Limits

This supply suits server builds requiring a dedicated 3.3 V rail at high current with active PFC and redundant protection features. It is not intended for systems needing multiple output voltages such as 12 V or 5 V main rails. Builders requiring current sharing should note the function is specified only for 24 V, 36 V and 48 V models. Buyers needing a 1U low-profile form factor should verify dimensions as this spec applies to the 300 W and 450 W variants.
