TFX 300W Bronze PSU for slim builds

The KHACHIMO PST-300DHF9 is a TFX form-factor power supply rated at 300 watts with 80 Plus Bronze efficiency. It suits small-form-factor desktops and replacement scenarios where a compact TFX unit is required. The unit has been tested and is supplied in new condition.

Replaces ageing TFX units of similar wattage

This supply upgrades older 300 W TFX power supplies that lack Bronze certification or have degraded over time. The efficiency gain is worthwhile when the existing unit is noisy, unstable or no longer meets the system’s power demands. It is not for builds needing higher wattage, modular cabling or standard ATX dimensions.

Questions about this item

What clearance does the TFX form factor of this 300W unit require in the case?

The TFX form factor is slimmer than standard ATX units, so it fits narrow small-form-factor chassis that accept TFX power supplies.

How is the PST-300DHF9 installed, and what step is often missed?

Mount the unit with the four TFX screw holes, connect the 24-pin ATX, CPU and peripheral cables, then set the 60 °C thermal switch to match your chassis airflow direction.
