Compact ATX power supply unit with matte black metal casing and rear fan grille

KHACHIMO

KHACHIMO 12V 4.3A 50W ATX 80 PLUS Gold power supply

SKU CH-9DGP-A9381

A 12 V, 4.3 A ATX unit delivering 50 W with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and LLC resonant DC-to-DC topology for clean, quiet power

  • TypeATX
  • Modern Standby compatible for fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • 12 V 4.3 A output provides 50 W ATX power for compatible systems

Purpose and Audience

The KHACHIMO 12V 4.3A 50W ATX 80 PLUS Gold power supply delivers 50 W of continuous power through a 12 V rail rated at 4.3 A. It is built for compact systems or industrial boards such as the LEA50F series that require an ATX-form-factor unit with high efficiency and low standby draw.

Who This Suits and Who Should Look Elsewhere

This unit suits builders who need a fan that stops completely at low and medium loads for silent operation and who value 80 PLUS Gold efficiency for reduced heat and power draw. It does not suit systems that demand multiple PCIe power connectors, higher total wattage, or modular cabling for custom cable routing.

Deciding Specification

The single specification that decides fit is the 12 V 4.3 A output, which fixes the maximum deliverable power at 50 W; verify that your board and all attached devices stay within this current limit before purchasing.

Questions about this item

Does my motherboard need a 12 V ATX connector to use this 50 W unit?

Yes — the supply delivers its full 50 W on the 12 V rail, so the board must provide a matching 12 V ATX input.

Will the Zero RPM fan mode stay silent when I keep an older mechanical hard drive in the same system?

The fan remains off at low and medium loads; a spinning mechanical drive adds little load, so silent operation is typically maintained.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Monitor input power at the wall while the system idles; a reading well below the DC output indicates the certified high-efficiency conversion is working.
