500W ATX Gold Power Supply

The KHACHIMO DPS-500XB A is a 500W ATX switching power supply built for modern desktop systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. This unit suits builders who want efficient, quiet power delivery for everyday computing and moderate gaming rigs.

Sustained-Load Efficiency and Acoustics

Resonant LLC topology with DC-to-DC conversion keeps output stable during extended workloads while reducing coil whine. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads, delivering near-silent operation. High Gold-rated efficiency lowers waste heat, helping the unit run cooler when the system is pushed for long periods.

Upgrade Path From Older or Lower-Rated Units

This supply replaces older ATX units that lack Modern Standby support or Gold-level efficiency, a change that matters for systems using deep sleep states. It is not for builds that need more than 500W of continuous power or require additional PCIe connectors beyond what this model provides.

Questions about this item

How loud is the 500W unit under all-day load?

The 80 PLUS Gold rating and resonant LLC topology keep waste heat low, while Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

What must my motherboard support to use Modern Standby with this PSU?

A motherboard with Modern Standby support and a standard ATX 24-pin connector enables the extremely fast wake-from-sleep times and better low-load efficiency.

Will the DPS-500XB A work with older ATX hardware I keep?

Yes, the ATX form factor and DC-to-DC conversion provide clean, consistent power compatible with legacy components while reducing coil whine.
