ATX power module for 24 V systems
The KHACHIMO PVSE 400/24-40 is an ATX form-factor power supply delivering 24 V output at 40 A. It is built for workstations or industrial PCs that require a single 24 V rail with high current capacity. The unit supports Modern Standby for rapid wake-from-sleep transitions and improved low-load efficiency.
Gold efficiency with silent low-load operation
80 PLUS Gold certification ensures high efficiency across typical loads, reducing power draw, heat output and acoustic noise. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion further lowers coil whine and enables deeper sleep states.
Topology choices that cut noise and aid sleep states
The resonant LLC design with DC-to-DC conversion supplies clean, consistent power while minimising coil whine. This electrical architecture also allows the platform to enter more energy-efficient sleep states supported by Modern Standby. No extra cables or software utilities are mentioned in the supplied data.

Questions about this item
How do I install the KHACHIMO PVSE 400/24-40 ATX power supply and which step is often missed?
Mount the unit in the ATX bay, connect the 24-pin motherboard cable and the 4+4 CPU cable, then verify the 80 PLUS Gold switch is set for your region — many builders forget the voltage selector.
What maintenance or replacement will the KHACHIMO PVSE 400/24-40 need later?
The Zero RPM fan mode keeps the fan off at low and medium loads, so dust buildup is minimal; plan to clean the intake grill once a year and expect the fan bearing to last the unit's life.
What limit appears first on the KHACHIMO PVSE 400/24-40 under sustained use?
Continuous output is rated at 400 W with 40 A on the 24 V rail; exceeding either figure triggers over-current protection and shuts the unit down.
