KHACHIMO

KHACHIMO M5-300S 200W 300W ATX power supply

SKU CH-8Y83-845SG

New ATX unit delivers 200 W rated and 300 W peak power with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC DC-to-DC topology for quiet, stable output

  • TypeATX
  • Fast wake and efficient sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold certification
  • Near-silent operation at typical loads thanks to Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC topology with DC-to-DC conversion
  • Reduced coil whine and quieter performance from advanced topology design

Modern Standby ATX Power Supply

This ATX power supply delivers a 200 W continuous rating with a 300 W peak capacity. It carries 80 PLUS Gold certification for high efficiency and runs a resonant LLC topology with DC-to-DC conversion for clean power delivery. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Quiet Builds and Compact Systems

The Zero RPM fan mode stops the fan completely at low and medium loads, making this unit a strong fit for silent-focused builds and space-constrained chassis. Builders who need higher continuous wattage for multi-GPU configurations or power-hungry workstations should look at a higher-rated unit.

200 W Continuous Rating

The single specification that decides fit is the 200 W continuous output. Match this figure to the total system power draw under load; if the build demands more sustained power, this supply will not be sufficient.

Perguntas sobre este artigo

How loud and hot does the 80 PLUS Gold unit get when it runs all day?

The 80 PLUS Gold rating keeps efficiency high, so waste heat and fan speed stay low; at light and medium loads the Zero RPM mode stops the fan completely for silent operation.

Which cables or connectors must my build already have for this ATX supply to work?

Standard ATX motherboard and peripheral connectors are required; the unit uses the common ATX form factor so it fits regular cases and motherboards.

Will the LLC resonant topology and DC-to-DC conversion cause issues with older components I keep?

The topology delivers clean, stable voltage rails that older hardware expects, and the Modern Standby support simply allows newer sleep states without breaking compatibility.
