  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode silences the unit at low load
  • Resonant LLC and DC-to-DC design delivers clean, stable power
  • ATX form factor fits standard desktop builds

1800W ATX Power Supply

This 1800W ATX power supply delivers high-capacity power for demanding desktop systems. It is built for builders who need reliable output for multi-GPU configurations or intensive workstation workloads. The unit carries 80 PLUS Gold certification for verified efficiency. Modern Standby compatibility enables rapid wake-from-sleep transitions.

Thermals Noise and Power Draw

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean power delivery while reducing coil whine. Gold-rated efficiency lowers overall power consumption and waste heat during normal use. The design supports energy-efficient sleep states for quieter idle behaviour.

Modern Standby Compatibility

Modern Standby support ensures extremely fast wake-from-sleep times and improved low-load efficiency. This feature is the deciding factor for systems that rely on instant resume from connected standby. Buyers whose platforms do not implement Modern Standby will not benefit from this capability. The supply remains fully functional as a standard ATX unit without it.

Questions about this item

How do I install the KHACHIMO 1800W ATX power supply and what step do people often miss?

Mount the unit in a standard ATX case, connect the 24-pin motherboard and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will the KHACHIMO 1800W supply need later?

The Zero RPM fan stays off at low and medium loads, so dust builds up more slowly; plan to blow out the heatsink once a year to keep the 80 PLUS Gold efficiency intact.

What limit appears first on the KHACHIMO 1800W unit during sustained heavy loads?

The 1800 W maximum output rating is the hard ceiling; the Resonant LLC topology with DC-to-DC conversion keeps voltages stable until that limit is reached.
