Server Chassis Power Supply

The NShi unit is a 12V 37.5A 450W AC DC power supply built into a desktop server chassis. It delivers single-output power through a 17-pin connector for compatible server configurations. The design includes active PFC function and constant current limiting circuit for stable operation. This product suits system integrators building or maintaining rack-mounted server infrastructure.

Sustained Load Behaviour

The power supply undergoes a 100% full load burn-in test before shipment to verify continuous performance. Built-in remote sense function compensates for voltage drop across the 17-pin harness under sustained demand. Constant current limiting protects the unit and connected components during prolonged high-draw scenarios. Active PFC maintains efficient power factor correction throughout extended operating periods.

Pre-Installation Checks

Verify your server backplane or motherboard accepts a 17-pin power connector with 12V 37.5A 450W single-output specification. Confirm the desktop chassis form factor fits your rack or mounting space constraints. Ensure the existing wiring harness pinout matches the supply connector layout before applying power. Check that system power requirements align with the 450W maximum output rating.

Questions about this item

Does the 450W unit generate noticeable heat or noise when running at 100% load all day?

The supply is 100% full-load burn-in tested, and its active PFC function helps reduce wasted energy that becomes heat.

What cables or connectors must I already have to plug the 17-pin output into my server backplane?

You need a matching 17-pin cable or backplane connector that carries the 12V 37.5A rails; the chassis itself supplies only the power module.

Will the constant-current limiting circuit protect an older 12V backplane that draws uneven current across its slots?

Yes, the built-in constant current limiting circuit clamps output at the rated 37.5A, preventing overload on legacy backplanes.
