Modern Standby Compatible 300W ATX Power Supply

This new KHACHIMO ATX power supply delivers 300W of continuous power for desktop systems. It holds 80 PLUS Gold certification for high efficiency, lower consumption and reduced heat. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and enables efficient sleep states. The unit is Modern Standby compatible for extremely fast wake-from-sleep times.

Builders wanting silent operation

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC design reduces coil whine for quieter performance overall. Modern Standby support ensures rapid wake speeds and better low-load efficiency. Systems requiring higher wattage than 300W or a different form factor should consider other options.

300W continuous power rating

This unit provides a maximum output of 300W, which determines whether it can support your chosen components. Verify the total power draw of your CPU, graphics card and peripherals against this figure. The 80 PLUS Gold rating confirms high efficiency across typical load ranges. Matching the power rating to your build is the single specification that decides suitability.

Perguntas sobre este artigo

How can I confirm the power supply is operating correctly after installation?

The 80 PLUS Gold certification means the unit runs efficiently at typical loads, and the Zero RPM fan mode keeps it silent until the load increases.

Which cables and accessories are included, and what must I purchase separately?

Standard ATX power cables for motherboard, CPU, and peripherals are included; no extra cables are required for a typical build.

Should I choose the HK401-11FP or the HK400-11FP model for my system?

Both deliver 300 W with identical 80 PLUS Gold efficiency, Modern Standby support, and Zero RPM fan operation; select the part number that matches your order.
