KHACHIMO Power Supply VS3-D4-B4-22 73-190-4047CE 2000W 15V120A

SKU CH-ERWC-6NDDD

An ATX power supply delivering 15 V at 120 A with 2000 W output, 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode switches the cooling fan off at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • ATX type power supply rated at 2000W with 15V 120A output

KHACHIMO 2000W ATX Power Supply

The KHACHIMO VS3-D4-B4-22 delivers 2000W at 15V and 120A for high-demand workstations or servers requiring reliable ATX power. It suits builders who need a robust unit certified to 80 PLUS Gold efficiency standards for continuous operation.

Sustained load efficiency and acoustics

Under continuous load the 80 PLUS Gold rating ensures high efficiency, reducing wasted energy and heat output. The Resonant LLC topology with DC-to-DC conversion maintains stable voltage regulation, while the Zero RPM fan mode keeps the unit silent until thermal thresholds require active cooling.

Modern Standby and build implications

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for compatible platforms. The ATX form factor fits standard chassis mounting points, though the 2000W capacity exceeds typical consumer requirements and may not suit compact builds.

Questions about this item

How loud is the VS3-D4-B4-22 when the 2000W unit runs continuously at full load?

The 80 PLUS Gold certification keeps waste heat low, and the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

What connectors must my motherboard already provide for this 15V 120A power supply to function?

It uses a standard ATX interface, so your motherboard needs a 24-pin main power connector plus the appropriate CPU and PCIe power headers for your components.

Will the VS3-D4-B4-22 work reliably with an older motherboard that only supports legacy sleep states?

Yes, the resonant LLC topology with DC-to-DC conversion delivers clean power and enables modern energy-efficient sleep states while remaining compatible with older platforms.
