Server-Grade Power Supply

The KHACHIMO R0X35A ARUBA 6400 is an 1800W ATX power supply built for high-density server and workstation deployments. It targets system integrators and IT teams who need reliable, high-output power in rack environments. The unit is supplied new and carries the manufacturer part number 0957-2509 DPS-1800AB-6A.

80 PLUS Gold Efficiency

The single specification that determines suitability is the 80 PLUS Gold certification, which guarantees high efficiency across typical server load ranges. This rating ensures lower energy waste and reduced operating costs for continuously running infrastructure. No other output or connector details are provided in the source data.

Thermals and Acoustics

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, delivering near-silent operation during idle or light workloads. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern standby sleep states. These features combine to keep noise and temperatures low in normal use.
