KHACHIMO

KHACHIMO BD-307 12V 180W 24V 360W power supply

SKU CH-TK8W-TTKAR

ATX power supply with 80 PLUS Gold efficiency, Modern Standby support and zero-RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby support for extremely fast wake times
  • 80 PLUS Gold efficiency for lower power draw and heat
  • Zero RPM fan mode keeps operation silent at low load
  • Resonant LLC topology with DC-to-DC conversion for clean power
  • Dual voltage output: 12V 180W and 24V 360W

Modern Standby Power Supply

The KHACHIMO BD-307 is an ATX power supply designed for systems that require dual 12 V and 24 V rails. It delivers up to 180 W on the 12 V outputs and 360 W on the 24 V outputs. This unit suits builders who need both voltage levels from a single modern source.

80 PLUS Gold Efficiency and Zero RPM Fan

Certified 80 PLUS Gold, the supply runs with high efficiency to reduce power draw, heat and noise. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for silent operation. Resonant LLC topology with DC-to-DC conversion keeps output clean and minimises coil whine.

ATX Form Factor with Dual Voltage Rails

The ATX form factor fits standard chassis layouts while providing the two distinct voltage rails your build requires. Modern Standby compatibility enables rapid wake-from-sleep and deeper low-power states. It does not suit systems that only need a single 12 V rail or lack space for a full-size ATX unit.

Questions about this item

How do I install the KHACHIMO BD-307 ATX power supply and which cable routing mistake should I avoid?

Mount the unit in a standard ATX case bay, secure it with four screws, then connect the 24-pin motherboard and CPU power cables; route cables behind the motherboard tray so they do not block the intake fan or the Zero RPM mode sensor.

What maintenance will the BD-307 need over its life and when should the fan be cleaned?

The 80 PLUS Gold unit requires only periodic dust removal; use compressed air through the fan grille every six to twelve months, or sooner if the Zero RPM mode stops engaging at low load.

Which limit appears first during sustained full-load operation on the 12V 180W or 24V 360W rails?

The 12V rail reaches its 180W ceiling before the 24V rail hits 360W, so continuous heavy 12V draw will trigger protection first.
