KHACHIMO 800W ATX Power Supply

The KHACHIMO RAS-2802P is an 800W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.

Suited for efficient, quiet builds.

This unit suits builders who want high efficiency, quiet operation and Modern Standby support in a standard ATX form factor. The Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Buyers who require fully modular cabling should look at other options. Systems demanding more than 800W of continuous power will need a higher-capacity unit.

800W 80 PLUS Gold ATX with Zero RPM fan

The single specification that decides fit is the 800W 80 PLUS Gold ATX rating combined with Zero RPM fan mode. This defines the power ceiling, efficiency class and acoustic profile for the build. Verify that your components stay within this 800W limit and that the fixed cable set matches your chassis layout. The 704-005 part number identifies this exact model for ordering.

Questions about this item

Will the 800W ATX unit fit and power an older motherboard that still uses a 24-pin main connector?

Yes, the supply follows the ATX form factor and provides a standard 24-pin main connector, so it will install and power legacy boards that accept that interface.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light or medium workloads the cooling fan stops completely; you can verify by listening for silence or watching the fan blades while the system idles.

Does the package include every cable needed for a typical desktop build, or must I buy extra connectors?

The box supplies the power supply unit and a fixed cable set covering the 24-pin motherboard, CPU, PCIe and peripheral connectors, plus mounting screws; no extra cables are required for a standard build.
