KHACHIMO TFX 300W Gold PSU

The KHACHIMO TFX 300W unit is an 80 PLUS Gold certified power supply built for small-form-factor PCs that use the TFX form factor. It targets builders assembling compact office machines, home-theatre PCs or slim upgrades where a standard ATX supply will not fit.

Installation notes for TFX builds

The supply follows the TFX mechanical standard and uses a conventional ATX pinout, so it slides into compatible chassis and connects to mainstream motherboards without adapters. Zero RPM fan mode eliminates noise at low load, but installers must verify that their case provides adequate airflow when the fan stops spinning under sustained medium loads.

Capacity and headroom for slim systems

The 300W rating delivers enough power for integrated-graphics desktops, entry-level discrete GPUs and typical office peripherals. Modern Standby support enables rapid wake from sleep, yet the fixed 300W ceiling leaves no margin for high-wattage graphics cards or heavy overclocking, so systems with power-hungry components should look elsewhere.

Highlights

  • Faster wake from sleep with Modern Standby support
  • Lower electricity draw thanks to 80 PLUS Gold efficiency
  • Silent running at light loads via zero-RPM fan mode
  • Stable, clean power delivery through resonant LLC and DC-to-DC design
  • Reduced coil whine for quieter operation under load

Questions about this item

How can I confirm the KHACHIMO TFX 300W supply is working correctly after installation?

The system should wake from sleep almost instantly thanks to Modern Standby support, the fan will stay off at low and medium loads, and you should hear no coil whine due to the resonant LLC and DC-to-DC design.

What comes in the box with the KHACHIMO TFX 300W unit and what must I buy separately?

The package includes the TFX form-factor power supply itself; any mounting screws, power cables or adapters required for your specific chassis are not included and must be sourced separately.

Which capacity of the KHACHIMO TFX series should I choose for my build?

The 300 W model is the only capacity listed, so it is the version to select when your system's peak draw fits within that limit and you want 80 PLUS Gold efficiency in a TFX footprint.
