  • TypeATX
  • Modern Standby support enables extremely fast wake-from-sleep
  • 80 PLUS Gold certification delivers high efficiency and lower consumption
  • Zero RPM fan mode stops the fan at low loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 24-pin, 10-pin and 8-pin connectors support X79 and X99 platforms

500W ATX power supply for compact servers

The KHACHIMO S10-500P1A delivers 500 watts of continuous power in an ATX form factor designed for 1U industrial and workstation chassis. It targets system integrators building X79 or X99 platforms that require a 24-pin, 10-pin and 8-pin connector set. Modern Standby compatibility ensures rapid wake-from-sleep response for always-on deployments.

Upgrade from lower-efficiency 1U units

This unit replaces older 1U supplies that lack 80 PLUS Gold certification and zero-RPM fan capability. The jump is worthwhile when a build demands lower idle power draw, reduced acoustic output at light loads, and support for deeper sleep states enabled by the resonant LLC topology with DC-to-DC conversion. It also satisfies installations requiring the specific 10-pin auxiliary connector found on certain server boards.

Headroom for multi-core workstations

The 500 watt rating comfortably handles dual-processor X79 or X99 configurations with multiple drives and add-in cards under typical workloads. Efficiency remains high across a broad load range, keeping waste heat low in restricted airflow environments. Capacity runs out when GPU compute accelerators or large storage arrays push sustained draw beyond the rated output, requiring a higher-wattage platform.

Perguntas sobre este artigo

Will the 24-pin, 10-pin and 8-pin connectors reach in a 1U chassis?

The unit is built for 1U IPC use and includes a 24-pin, a 10-pin and an 8-pin connector to match X79 and X99 boards.

Which cables must be seated before the first boot?

Connect the 24-pin main power, the 8-pin CPU power and the 10-pin auxiliary connector; missing the 10-pin is the most common oversight.

How do I keep the fan running quietly over time?

The Zero RPM mode stops the fan at low load; vacuum dust from the intake grille every few months to maintain airflow when the fan does spin.
