KHACHIMO

KHACHIMO ATX 300W Power Supply 80 PLUS Gold

SKU CH-5S3Y-ZHVPW

A 300 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for quiet, low-power operation

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at low load through Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC with DC-to-DC conversion
  • Reduced coil whine for quieter performance thanks to advanced topology

Purpose and Audience

The KHACHIMO ATX 300W power supply delivers 80 PLUS Gold efficiency for standard desktop builds. It suits users who want lower power draw, cooler running temperatures and quieter operation in a basic system.

Who It Suits and Who Should Look Elsewhere

Builders needing Modern Standby support and a Zero RPM fan mode for silent low-load work will benefit. Systems requiring more than 300W output or auxiliary connectors not listed here should look at higher-capacity units.

Compatibility Checklist

Verify that your motherboard uses a standard ATX power connector and that the 300W rating covers the combined draw of your CPU, graphics card and drives. Confirm the physical dimensions fit your case before ordering.

商品問答

Does this PSU include the P8 and P9 connectors my Antec AT board requires?

Yes, the unit is built with the P8 and P9 connectors used by Antec AT motherboards so no adapter is needed.

Will the Zero RPM fan mode still engage if I keep an older graphics card that draws steady idle power?

The fan stops at low and medium loads; a legacy card’s idle draw usually stays within that range so the fan remains off.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Use software that reports input and output wattage; the ratio should match Gold‑level efficiency at typical loads.
