KHACHIMO DPST-1630AB A 1630W power supply

SKU CH-V2YZ-AQ7WG

An ATX power supply delivering 1630 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion for clean power and quiet operation

  • Product 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 stops the fan 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
  • 1630W ATX power supply supports high-performance system builds

1630W ATX power supply

The KHACHIMO DPST-1630AB A delivers 1630W of continuous power through a standard ATX form factor. It targets workstation and high-end desktop builders who need substantial headroom for multi-GPU arrays or heavily overclocked components. The unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times.

Capacity and headroom

At 1630W this unit comfortably handles dual high-wattage graphics cards, high-core-count CPUs and numerous drives simultaneously. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation across the full load range. Systems requiring more than 1630W or those needing redundant power modules will need a different class of supply.

Bundled technologies

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for supported platforms. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The resonant LLC topology with DC-to-DC conversion reduces coil whine and enables more energy-efficient sleep states.

Questions about this item

Will the ATX form-factor DPST-1630AB fit in the same case and use the same motherboard connectors as my current ATX power supply?

Yes, the ATX form factor matches standard case mounting holes and the 24-pin ATX, CPU and PCIe connectors found on existing ATX motherboards.

How can I verify the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

Monitor system power draw with a wall meter to confirm high efficiency at typical loads, and listen for fan silence during idle or light workloads to confirm Zero RPM mode.

Which cables are included with the DPST-1630AB and what might I need to purchase separately?

The unit ships with a fixed set of ATX, CPU and PCIe cables; if your build requires additional PCIe connectors or specialty cables such as 12VHPWR, those must be sourced separately.
