Rectangular ATX power supply unit with matte black metal casing and visible cooling fan grille

KHACHIMO

KHACHIMO LL2000FC 2000W ATX Power Supply

SKU CH-8JQF-ANG2W

ATX 2000W power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for clean, quiet power delivery

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low load for silent running
  • Resonant LLC with DC-to-DC delivers clean, stable power and less coil whine
  • 2000 W ATX output handles multi-GPU and server workloads

High-capacity ATX power for multi-GPU systems

This 2000W ATX power supply targets builders running multiple high-end video cards or server-grade workloads. The unit delivers the headroom needed for dense GPU configurations while maintaining stable rails across heavy sustained loads. It suits mining rigs, render nodes and workstations that demand continuous high-wattage delivery.

Gold efficiency with semi-passive cooling

80 PLUS Gold certification keeps waste heat and power draw low across the load range. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, while resonant LLC topology with DC-to-DC conversion reduces coil whine and supports Modern Standby for fast wake-from-sleep and better low-load efficiency.

Clean power topology for dense builds

Resonant LLC with DC-to-DC conversion provides tight voltage regulation and low ripple, protecting sensitive components in multi-card arrays. The design prioritises consistent output and reduced acoustic noise, making it practical for rack or workstation environments where several units may run side by side. Modern Standby compatibility ensures quick resume from sleep states.

Questions about this item

How do I install the KHACHIMO LL2000FC and which cable connection is often missed?

Mount the unit in a standard ATX case bay, secure it with four screws, then attach the 24-pin motherboard, CPU and PCIe cables; the step most builders forget is plugging in the auxiliary CPU power connector required for full 2000 W delivery.

What maintenance or part replacement will this power supply need over time?

The 80 PLUS Gold certified unit uses a Zero RPM fan that only spins under load, so dust buildup is minimal; plan to clean the intake grill once a year and replace the fan bearing only if noise appears after several years.

What limit appears first when the LL2000FC runs at sustained high load?

Continuous output is capped at 2000 W, and the 80 PLUS Gold efficiency target of 90 % at typical load means heat rises quickly; the thermal protection circuit will throttle or shut down the unit before any voltage rail drops out of spec.
