Compact TFX power supply for small-form-factor

This KHACHIMO TFX unit delivers 450 W of continuous power in a slim form factor that fits slimline desktops and mini-ITX cases where standard ATX units cannot. It is aimed at system integrators and DIY builders upgrading proprietary OEM chassis such as FSP 220 S, 530 S, 545 S or 620 S platforms. Buyers who need higher wattage for multi-GPU workstations or full-size ATX cases should look elsewhere.

80 PLUS Gold efficiency with semi-passive cooling

The 80 PLUS Gold rating means the supply runs at high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. A Zero RPM fan mode stops the fan completely at low and medium loads, so the system stays near-silent during office work or media playback. Resonant LLC topology with DC-to-DC conversion further cuts ripple and suppresses coil whine for quieter operation overall.

Modern Standby support enables instant wake

Modern Standby compatibility allows the PC to enter ultra-low-power sleep states and resume almost instantly, improving responsiveness for always-on desktops and living-room PCs. The DC-to-DC design makes these deeper sleep states stable without voltage droop. No extra cables or software utilities are mentioned in the specifications.

Questions about this item

How do I install this TFX power supply in a slimline case and which step is often missed?

Mount the unit using the four rear screws, connect the 24-pin ATX and CPU power cables, then verify the Modern Standby cable is seated so wake-from-sleep works.

What maintenance or replacement will this 450 W unit need over time?

The Zero RPM fan mode reduces bearing wear, so only occasional dust removal from the intake grille is required; no user-serviceable parts inside.

Which limit appears first when this supply runs at sustained load?

The 80 PLUS Gold efficiency target drops above 50 °C internal temperature, so prolonged heavy loads will hit thermal protection before the 450 W rating is exceeded.
