KHACHIMO 1400W ATX PSU for Advantech Systems

The KHACHIMO FSP1400-21DRM is a new 1400W ATX power supply built for ADVANTECH platforms. It targets integrators and technicians who need high-output, reliable power for demanding industrial or server workloads. The unit carries 80 PLUS Gold certification for high efficiency across typical load ranges. It is not suited for builders who need modular cabling or standard consumer form factors.

Sustained Load Behaviour with LLC Topology

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power under continuous demand. The design reduces coil whine and supports modern energy-efficient sleep states during extended operation. 80 PLUS Gold efficiency lowers power draw and heat output when the system runs at high load for long periods. Zero RPM fan mode keeps the unit silent at low and medium loads by stopping the fan completely.

Installation Notes and Common Issues

The power supply uses a standard ATX form factor for chassis compatibility with supported ADVANTECH hardware. Fixed cables require careful routing in dense enclosures where space is tight. Modern Standby compatibility enables extremely fast wake-from-sleep times for supported motherboards. Installers should verify connector pinouts match the target backplane before applying power.

Questions about this item

How loud is the fan when the 1400W supply runs continuously at high load?

The Zero RPM mode keeps the fan off at low and medium loads for near-silent operation; at higher loads the fan spins to maintain cooling.

Which cables or connectors must I already have to install this ATX unit?

Standard ATX 24-pin, EPS/CPU and PCIe cables are required; the supply uses the usual ATX pin-out so existing modular cables from the same platform will fit.

Will the 80 PLUS Gold efficiency work with an older motherboard that lacks Modern Standby support?

Yes, the 80 PLUS Gold rating applies regardless of motherboard features; Modern Standby compatibility simply adds faster wake times on supported platforms.
