SKU CH-H3FV-VD387

TFX 275 W unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for quiet, reliable small-form-factor power

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • High efficiency cuts power draw and heat with 80 PLUS Gold certification
  • Near-silent operation at low loads via Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC topology with DC-to-DC conversion
  • Reduced coil whine and quieter sleep states through advanced topology

TFX power supply for compact builds

This 275 W unit follows the TFX form factor, making it suitable for slim HTPC cases and small-form-factor systems that cannot accept a standard ATX power supply. It targets builders who need reliable power in a tight chassis without stepping up to a larger enclosure.

80 PLUS Gold efficiency and Zero RPM fan

The 80 PLUS Gold rating means high efficiency at typical loads, which reduces waste heat and keeps internal temperatures lower. A Zero RPM mode stops the fan completely at low and medium loads, so the system stays near-silent during everyday desktop work or media playback.

Resonant LLC topology with DC-to-DC conversion

This design delivers clean, stable voltages and helps suppress coil whine, contributing to quieter operation overall. Modern Standby compatibility allows faster wake-from-sleep transitions and supports deeper, more energy-efficient sleep states for compatible platforms.

Questions about this item

How do I install the GT-275 in a TFX case and which step is often missed?

Slide the unit into the TFX bay, secure the four mounting screws, then attach the 24-pin ATX and 4+4-pin CPU connectors; the step often missed is plugging the 4+4-pin CPU cable near the socket.

What maintenance will the GT-275 need over time?

The Zero RPM fan mode keeps the fan off at low and medium loads, reducing wear; occasional dust removal from the intake grille is the only upkeep required.

What limit appears first under sustained load on the GT-275?

The 275 W continuous output ceiling is reached before thermal limits, so total system draw must stay below that figure.
