400W TFX Power Supply

This 400W TFX switching power supply delivers ATX-standard power in a compact form factor for small-form-factor desktop builds. It accepts 220V AC input and provides a 12-pin connector layout compatible with select OEM chassis.

80 PLUS Gold and Zero RPM Fan

The unit carries 80 PLUS Gold certification for high efficiency that reduces waste heat and lowers overall power draw. At low and medium loads the fan stops completely, enabling near-silent operation during everyday tasks.

Modern Standby Support

Resonant LLC topology with DC-to-DC conversion enables Modern Standby compatibility for extremely fast wake-from-sleep times and improved low-load efficiency. Buyers whose systems lack Modern Standby support will not benefit from this feature.

Domande su questo articolo

How do I install the KHACHIMO 12Pin 400W TFX power supply in a small-form-factor case, and what step is often missed?

Mount the TFX unit in the chassis, connect the 12Pin motherboard cable and any peripheral leads, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will the 400W switching supply need after extended use?

Periodically blow dust from the fan intake; the Zero RPM mode keeps the fan off at low load, so dust builds up slowly, but cleaning once a year maintains the quiet, cool operation promised by the 80 PLUS Gold design.

What limit appears first when the 400W unit runs at sustained high load?

The 400W continuous-output ceiling is reached before thermal limits, so total system draw must stay below that figure to avoid protection shutdown.
