KHACHIMO ENH-2180-1 800W ATX Power Supply

SKU CH-2F7C-VZWR4

An 800W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for silent, low-power sleep states

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC with DC-to-DC conversion
  • 800 W ATX output for demanding system builds

800W ATX PSU for Modern Standby Builds

This 800W ATX power supply targets builders who need reliable power delivery with Modern Standby support for rapid wake-from-sleep. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and electricity costs. The resonant LLC topology with DC-to-DC conversion provides stable voltage regulation for sensitive components. It suits workstations and performance desktops requiring consistent 800W output.

Gold Efficiency with Zero RPM Silence

The unit delivers its full 800W rating while maintaining Gold-level efficiency, keeping temperatures lower under sustained loads. At low and medium power draw the fan stops completely, eliminating noise during idle or light productivity tasks. Headroom exists for multi-core CPUs and mid-range GPUs, though dual high-end graphics configurations would exceed the 800W limit. Peak transient spikes are handled by the DC-to-DC design without voltage droop.

2U Form Factor with LLC Topology

Built in a 2U chassis, this supply fits rackmount servers and compact cases where vertical space is limited. The resonant LLC topology reduces coil whine, a common irritant in quiet environments, while enabling deeper sleep states for Modern Standby compliance. Standard ATX connectors ensure broad motherboard compatibility without proprietary cables. The fixed cable layout simplifies installation but offers no modularity for cable management.

Questions about this item

Will the ENH-2180-1 work with a motherboard that only has a 20-pin main power connector?

The unit follows the ATX form factor and provides standard 20+4 pin and CPU power connectors, so it fits older boards that use a 20-pin socket.

How can I confirm the Zero RPM Fan Mode is active after I install the ENH-2180-1?

Under light loads the fan stops completely; you can verify by listening for silence or watching the fan blades while the system idles.

Does the ENH-2180-1 include all cables needed for a typical build, or must I buy any separately?

The power supply ships with the fixed ATX cables attached; no extra cables are required for a standard installation.
