KHACHIMO PS-8501-1 500W ATX PSU

This KHACHIMO unit is a 500 watt ATX power supply built with resonant LLC topology and DC-to-DC conversion. It delivers 80 PLUS Gold certified efficiency for lower power draw and cooler running. The design targets modern desktop builds that require stable, clean power delivery.

Ideal for Modern Standby systems and quiet builds

The power supply suits users who want fast wake-from-sleep times and near-silent operation at low to medium loads through its Zero RPM fan mode. It is not for systems that demand higher wattage output or builders who need modular cable management for custom routing.

No bundled accessories or software included

The product ships as the power supply unit alone without extra cables, adapters or configuration utilities. Installation relies on standard ATX connections already present in the chassis. Buyers should verify their case and component cable requirements separately.

Questions about this item

What motherboard power connectors does the PS-8501-1 need to work?

The PS-8501-1 uses standard ATX 24-pin main and 4/8-pin CPU connectors, so your motherboard must provide matching sockets.

Will the 500W PS-8501-1 power an older graphics card that still uses a 6-pin PCIe connector?

Yes, the unit supplies up to 500 W through its native 6/8-pin PCIe cables, so a legacy 6-pin card will run normally.

How can I confirm the Zero RPM fan mode is active after installing the PS-8501-1?

Under light load the fan stops completely; listen for silence and check that the 80 PLUS Gold efficiency rating is reported by monitoring software.
