KHACHIMO DPS-900EB A 900W ATX Power Supply

Workstation-class 900W ATX unit

This 900W ATX power supply is built for the KHACHIMO Workstation P720 and P520 platforms. It delivers the stable, high-capacity power those workstations demand for professional workloads. The unit is new and carries the supplier part number 54Y8979. It is not intended for builders who need a standard retail form factor or a different connector layout.

Sustained-load behaviour with LLC and DC-to-DC

Resonant LLC topology paired with DC-to-DC conversion keeps voltage regulation tight during extended rendering or compute sessions. The design maintains clean, consistent power without the ripple that can appear under long-duration heavy draw. 80 PLUS Gold certification confirms high efficiency across the load range, reducing waste heat during marathon workloads. This topology also supports deeper, more energy-efficient sleep states between tasks.

Thermals, noise and power draw in normal use

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, giving near-silent operation during typical office work. Modern Standby compatibility enables extremely fast wake-from-sleep times while preserving low-load efficiency. The combination of Gold-rated efficiency and the advanced topology lowers overall power consumption and keeps internal temperatures down when the system is active. Coil whine is reduced by the resonant design for quieter background operation.
