KHACHIMO ACE-850AP-RS-24 850W ATX power supply

Industrial 850W ATX unit

The KHACHIMO ACE-850AP-RS-24 is an 850W ATX power supply built for industrial control systems and high-reliability workstations. It delivers continuous 24V output with Modern Standby compatibility for fast wake-from-sleep transitions. The unit suits builders who need server-grade efficiency in a standard ATX footprint. It is not for compact SFX builds or systems requiring multiple 12VHPWR connectors.

Gold efficiency with zero-fan mode

80 PLUS Gold certification ensures high efficiency operation for lower power consumption, less noise, and cooler temperatures across typical loads. The Zero RPM Fan Mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine and enabling deeper sleep states. This combination keeps acoustics minimal during idle and light workloads.

Standard ATX fit with Modern Standby

The ATX form factor fits standard chassis layouts without proprietary brackets or cable routing constraints. Modern Standby support frees the system to enter and exit low-power states quickly, reducing downtime in always-on environments. DC-to-DC conversion simplifies the internal cable harness by generating minor rails from the primary 24V output. Builders needing redundant hot-swap modules or non-ATX mounting patterns should look elsewhere.
