530W ATX Power Supply

The KHACHIMO YM-2531B delivers 530W of continuous power in a standard ATX form factor. It targets system builders who need reliable efficiency for modern desktop platforms and value low-noise operation at typical workloads.

Modern Standby and Gold Efficiency

This unit replaces older power supplies that lack Modern Standby compatibility and 80 PLUS Gold certification. The upgrade is worthwhile when faster wake-from-sleep behaviour and reduced idle power draw are priorities for the build.

Resonant LLC with Zero RPM Fan

A resonant LLC topology paired with DC-to-DC conversion supplies clean power while enabling the fan to stop completely at low and medium loads. This frees the chassis from unnecessary airflow demand during light use and suits quiet-focused configurations.

Questions sur cet article

What ATX case clearance does the 530 W unit require?

The supply follows the standard ATX form factor, so it fits any case with an ATX power-supply bay and matching rear cut-out.

How do I enable the Zero RPM fan mode on the YM-2531B?

Zero RPM activates automatically at low and medium loads; no BIOS or software setting is needed, just ensure the fan header is connected if your motherboard monitors PSU fan speed.

What long-term upkeep does the Gold-certified 530 W unit need?

Periodically clean dust from the intake grill to maintain the high efficiency and low temperatures that the 80 PLUS Gold rating and LLC topology are designed to deliver.
