SKU CH-5T7F-CJCAP

Compact 12 V ITX FLEX unit delivers 400 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology for quiet, clean power

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified for high efficiency and lower power consumption
  • 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
  • 12V ITX FLEX 1U form factor fits compact S3 R47 K39 builds with 400W output

Compact 1U ITX power supply for small-form-factor

The KHACHIMO 12V FLEX unit fits 1U server chassis and mini-ITX cases where a standard ATX supply will not fit. It delivers 400 W of continuous power for compact workstations or embedded systems. Builders needing a full-size ATX footprint or higher wattage should look elsewhere.

12 V single-rail output with 80 PLUS Gold efficiency

The supply provides its full 400 W on a single 12 V rail, simplifying cable routing and load balancing in tight enclosures. Gold certification guarantees at least 80 % efficiency at typical loads, reducing waste heat and electricity cost.

Zero-RPM fan mode and resonant LLC topology under

At low and medium loads the fan stops completely for silent operation, while the resonant LLC design with DC-to-DC conversion keeps voltage regulation tight and suppresses coil whine during extended use. Modern Standby support enables rapid wake-from-sleep without power spikes.

Perguntas sobre este artigo

What does the 400W rating mean for a typical build?

The 400W rating is the maximum continuous power the unit can deliver across all rails, so the combined load of CPU, GPU, drives and peripherals should stay below that figure.

Which ATX version does the power supply follow?

The unit is built to the ATX form factor, meaning it uses the standard 24-pin main connector, 4/8-pin CPU connector and peripheral connectors defined by that specification.

Will the 1U height fit in my slim chassis?

The 1U form factor measures one rack unit tall, so the case must accommodate that height and provide the matching mounting holes for a Flex ATX power supply.
