24 V 75 W ATX Power Unit

The KHACHIMO FCA75F-24 is a 24 V ATX power supply rated at 75 W with a 3.1 A output. It targets compact or low-power system builds that require an ATX form factor and modern standby support.

80 PLUS Gold And Zero RPM Fan

Gold certification means the unit runs at high efficiency across typical loads, reducing waste heat and keeping noise low. The Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion delivers clean power and suppresses coil whine.

Standard ATX Installation

The supply fits a regular ATX mounting pattern and uses standard ATX connectors, so it drops into compatible cases without adapters. Ensure the 24 V 75 W rating matches the total system draw; undersizing will cause instability or shutdown under load.

Questions about this item

What maintenance does the cooling fan in the FCA75F-24 require over time?

The fan uses a Zero RPM mode that stops it completely at low and medium loads, reducing wear. Periodic dust removal from the intake vents is the only upkeep needed.

Which limit appears first when the 75W unit runs at full load continuously?

The 75W maximum output power is the hard ceiling; once the 24V rail reaches its 3.1A rating the supply cannot deliver more without triggering protection.

How much noise and heat does the power supply produce during all-day operation?

80 PLUS Gold efficiency keeps waste heat low, and the Zero RPM fan mode keeps the unit silent at typical loads; the fan only spins under heavier demand.
