KHACHIMO

KHACHIMO 2000W ATX power supply YSEC2000AM

SKU CH-A2ZD-PR9Y9

An ATX power supply delivering 2000 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower power consumption and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 2000 W output capacity for demanding high-performance systems

2000W ATX Power Supply

The KHACHIMO YSEC2000AM is a 2000W ATX power supply built for servers and workstations that demand high continuous output. It suits system integrators deploying dense compute nodes where the CRPS form factor is required. The unit delivers modern standby support for rapid wake cycles and improved low-load efficiency.

80 PLUS Gold Efficiency Upgrade

It replaces older gold-rated or bronze-rated CRPS modules that lack modern standby or zero-fan operation. The jump is worthwhile when the platform needs lower idle power, quieter acoustics at medium load, and support for deeper sleep states. Older units without DC-to-DC conversion cannot match the transient response or coil-whine reduction this topology provides.

Sustained Load Behaviour

Resonant LLC topology with DC-to-DC conversion maintains clean, consistent power during extended heavy loads. Zero RPM fan mode keeps the fan off at low and medium loads, reducing acoustic output until thermal conditions require active cooling. Gold certification ensures high efficiency continues under sustained demand, limiting waste heat and keeping component temperatures lower.

Questions about this item

What physical dimensions does the 2000W ATX power supply require for mounting?

This unit follows the standard ATX form factor, so it fits any case with an ATX PSU bay and uses the usual four-screw mounting pattern.

How is the power supply installed, and which step is often missed?

Secure the unit with four screws, connect the 24-pin ATX, CPU and GPU cables, then verify the rear voltage switch matches your mains supply before powering on.

What maintenance will the 2000W unit need over time?

Clean dust from the fan intake periodically; the Zero RPM mode keeps the fan off at low load, reducing wear, but the 80 PLUS Gold efficiency depends on unobstructed airflow.
