Rectangular black metal ATX power supply unit with cooling fan and cable bundle

KHACHIMO

KHACHIMO V200 530 531 300W Power Supply

SKU CH-8DW3-KK9W4

Delivers 300 W of 80 PLUS Gold ATX power with Modern Standby support, zero-RPM fan mode and LLC resonant DC-to-DC topology for clean, quiet output

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

Ready for Modern Standby PCs

This 300W ATX power supply is built for desktops that use Modern Standby sleep states. It delivers 80 PLUS Gold efficiency to cut waste heat and lower running costs. The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion keeps output clean and reduces coil whine.

Replaces older low-efficiency units

Swapping out a basic bronze or unrated supply brings quieter performance and faster wake-from-sleep response. The jump is worth it when your current unit runs its fan constantly or struggles with low-power states. Gold-rated efficiency also reduces overall power draw during everyday workloads. Builders who need higher wattage for discrete graphics should look elsewhere.

Check ATX fit and cable reach

Verify your case accepts a standard ATX power supply and that the fixed cables reach your motherboard and drive connectors. Confirm the 24-pin main connector and any CPU power plugs match your board layout. Ensure the physical depth clears internal brackets or drive cages. No modular cables are included, so routing space must accommodate the full loom.

Questions about this item

Does the ATX form-factor unit fit a standard ATX case?

Yes, the ATX type matches standard ATX mounting holes and dimensions for typical desktop cases.

How do I connect the power supply and what step is often missed?

Mount the unit with four screws, plug the 24-pin ATX and 8-pin CPU cables, then switch the rear I/O rocker to 1 before powering on.

When will the 80 PLUS Gold fan need cleaning or replacement?

The Zero RPM mode keeps the fan off at low and medium loads, so dust builds slowly; clean the intake grill once a year and replace the fan only if bearing noise appears.
