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.

Domande su questo articolo

How loud is the 900W unit under continuous load?

The 80 PLUS Gold certified design keeps heat low, and the Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running.

Which connectors must my workstation already have to use this PSU?

It fits standard ATX bays and uses the native power connectors found on Lenovo P720 and P520 workstations.

Will the DPS-900EB A work with older components I keep in the same build?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power that supports legacy parts alongside modern sleep states.
