SKU CH-CMJ7-GXE4K

A 500 W Flex ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support for compact builds

  • TypeATX
  • Modern Standby support enables rapid wake-from-sleep transitions
  • 80 PLUS Gold certification delivers high efficiency for lower power draw and cooler running
  • Zero RPM fan mode stops the fan at low to medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion supplies clean, stable power and reduces coil whine
  • Flex ATX form factor fits compact 1U and small-form-factor builds

Form-factor fit

This KHACHIMO unit is a 500 W Flex ATX power supply built for compact chassis such as 1U servers or small-form-factor PCs. The 39 mm height allows installation where standard ATX units will not fit, making it suitable for space-constrained builds that still demand full ATX electrical compliance.

Efficiency and acoustics

80 PLUS Gold certification confirms high conversion efficiency across typical loads, reducing waste heat and enabling the Zero RPM fan mode to stay inactive longer. Resonant LLC topology with DC-to-DC conversion delivers tight voltage regulation and lowers coil whine, while Modern Standby support lets the system wake from sleep almost instantly.

Pre-install checks

Verify that your case accepts a 39 mm tall Flex ATX power supply and that the mounting holes align with the unit’s bracket. Confirm the motherboard uses standard ATX power connectors and that the total system draw stays within the 500 W rating. Ensure the AC inlet and fan exhaust have adequate clearance for airflow.

Questions about this item

How often will the fan in this KHACHIMO FSP500-50FSPT need replacement?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so the fan runs less and should last longer before any replacement is needed.

What is the first limit reached when this 500W unit runs at full load continuously?

The 500W rated output is the hard limit; sustained loads above that will trigger protection or shutdown.

How loud and hot does this 80 PLUS Gold supply get during all-day operation?

At low and medium loads the fan stays off for near-silent running, and Gold efficiency keeps heat and power draw lower than less efficient units.
