  • TypeATX
  • Instant wake and efficient sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw, heat and noise
  • Fan stops completely at low loads for silent running
  • Resonant LLC with DC-to-DC delivers clean, stable power
  • Compact 1U flex form factor fits small ITX builds

Compact 1U Flex ATX design

The KHACHIMO ITX FLEX 1U K39 fits small-form-factor builds that require a 500 W ATX supply. Its 1U height suits rackmount or slim chassis where standard PSUs cannot be installed. The unit is new and carries 80 PLUS Gold certification for efficient power delivery.

Sustained-load behaviour

At low and medium loads the fan remains off completely, keeping acoustic output near zero during typical desktop work. Resonant LLC topology with DC-to-DC conversion maintains stable voltages and reduces coil whine when the system runs continuously. Modern Standby support enables rapid wake-from-sleep without efficiency penalties.

Pre-installation checks

Verify that your case accepts a 1U Flex ATX form factor and provides the mounting pattern used by this supply. Confirm the total system draw stays within the 500 W rating, especially if a discrete graphics card is present. Ensure the supplied cable set matches the motherboard and peripheral connectors required by your build.

Questions sur cet article

Does the 80 PLUS Gold 500W unit run quietly under continuous load?

The 80 PLUS Gold certification means high efficiency, which reduces waste heat and keeps fan speeds lower. A Zero RPM mode stops the fan completely at low and medium loads for near-silent operation.

Which cables or connectors must my build already provide for this Flex ATX supply?

The unit follows the ATX form factor and standard ATX pin-outs, so your case and motherboard need matching ATX power connectors and mounting points for a 1U Flex ATX design.

Will the LLC resonant topology with DC-to-DC conversion work with older motherboards that use traditional sleep states?

Yes. The topology enables modern energy-efficient sleep states while remaining fully compatible with legacy ACPI sleep modes used by older boards.
