2U 480W ATX power supply

The KHACHIMO PR2102NS is a 2U form-factor ATX unit rated at 480W, designed for rack-mount or compact server chassis where vertical space is limited. It suits system integrators building dense compute nodes or workstations that require reliable, efficient power delivery in a shallow enclosure.

Modern Standby and efficiency

Certified 80 PLUS Gold, the supply maintains high efficiency across typical loads, reducing waste heat and acoustic output. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency, while the resonant LLC topology with DC-to-DC conversion delivers clean power rails and supports deeper sleep states.

Zero RPM fan mode and headroom

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during idle or light workloads. The 480W capacity handles multi-core CPUs, moderate GPU configurations, and multiple storage devices; builds requiring dual high-end graphics cards or extreme overclocking headroom will exceed its rated output.

Questions about this item

What happens when the 480 W limit is reached under sustained load?

The unit will trigger its over-power protection and shut down to prevent damage once the 480 W continuous rating is exceeded.

How does the Zero RPM Fan Mode affect noise and heat during all-day operation?

The fan stays off at low and medium loads for silent running; it spins up only when higher loads demand active cooling.

Which motherboard power connectors must my system already provide for this ATX unit?

A standard 24-pin ATX main connector and the required 4-pin or 8-pin EPS CPU power connector are essential.
