4400W ATX Power Supply

The KHACHIMO ASR 9912 9922 990 delivers 4400W of continuous power in a standard ATX form factor. It is built for workstations and servers that demand very high output from a single unit. The 80 PLUS Gold certification confirms high efficiency across typical load ranges.

Sustained load behaviour

Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight during extended heavy workloads. The design reduces coil whine and supports energy-efficient sleep states without instability. 80 PLUS Gold efficiency lowers waste heat so internal temperatures stay manageable over long periods.

Build quality and connectors

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The PWR-4.4KW-DC-V3 341-0669-03 DHF-2DC-4400W designation identifies the exact unit for spare-part tracking.

Questions about this item

How much noise does the KHACHIMO ASR 9912 9922 990 make during all-day operation?

A Zero RPM Fan Mode stops the fan completely at low and medium loads for near-silent running, while 80 PLUS Gold efficiency reduces waste heat so the fan stays off longer.

What must I already own to install the KHACHIMO ASR 9912 9922 990?

You need an ATX-compatible case and motherboard with standard 24-pin and CPU power connectors, plus the DC input source required by this 4400 W unit.

Will the KHACHIMO ASR 9912 9922 990 work reliably with older hardware I keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and supports modern low-power sleep states used by newer and older components alike.
