KHACHIMO Modular 80 PLUS Gold 460W 1U Power Supply

SKU CH-XZQ0-0G793

An 80 PLUS Gold 460W modular 1U ATX supply with Modern Standby, Zero RPM fan mode and resonant LLC DC-to-DC topology for quiet, efficient power

  • TypeATX
  • Modern Standby support delivers rapid wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification provides high efficiency for lower power use, less noise and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion supplies clean power, reduces coil whine and enables efficient sleep states
  • Modular 460 W 1U ATX design replaces the 400 W unit in a compact form factor

Compact 1U Power Supply for IPC Builds

This KHACHIMO unit is a 460 W ATX power supply built to the 1U form factor for industrial and embedded chassis. It replaces the earlier SS-400H1U model and carries 80 PLUS Gold certification for efficient power delivery. The modular cabling helps keep airflow clear inside tight enclosures.

Sustained Load Efficiency and Acoustics

The resonant LLC topology with DC-to-DC conversion maintains clean voltage regulation during continuous operation rather than brief peaks. Zero RPM fan mode keeps the fan stopped at low and medium loads, reducing noise and wear. Modern Standby compatibility allows rapid wake-from-sleep while maintaining high efficiency at light loads.

Modular Cabling and Chassis Integration

Fully modular connectors let installers use only the cables required by the specific backplane or drive configuration. The 1U height fits standard rackmount and slimline industrial cases without exceeding the vertical clearance. Gold-rated efficiency lowers waste heat, easing thermal management in densely packed systems.

Questions about this item

How quiet does the 80 PLUS Gold 460W unit stay when it runs all day?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, and the resonant LLC topology with DC-to-DC conversion reduces coil whine for near-silent operation.

What motherboard power connections must already be present for this 1U supply to work?

It uses the standard ATX 24-pin main connector and a CPU EPS connector, matching the ATX form factor stated in the specifications.

Will this 460W replacement work with an older SS-400H1U installation without changes?

The supplier notes it replaces the SS-400H1U directly, keeping the same 1U footprint and ATX pin-out for a drop-in swap.
