Rectangular silver ATX power supply unit with fan grille

KHACHIMO

KHACHIMO 1600W ATX power supply 80 PLUS Gold

SKU CH-P379-SCVH2

An 80 PLUS Gold ATX unit delivering 1600W with Zero RPM fan mode and Modern Standby support for silent, efficient power

  • Product typeATX
  • Modern Standby support gives extremely fast wake-from-sleep times and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 1600W ATX output supplies ample power for demanding system builds

1600W ATX Power Supply for High-Performance Builds

This KHACHIMO unit delivers 1600W of continuous power through an ATX form factor, making it suitable for demanding workstations and enthusiast desktops with multiple GPUs or high-end CPUs. It carries 80 PLUS Gold certification for high efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery and reduces coil whine. Modern Standby compatibility ensures extremely fast wake-from-sleep times and better low-load efficiency.

Efficiency Headroom and Load Behaviour

At typical loads the Gold-rated design keeps waste heat and fan noise low, while the 1600W ceiling handles sustained heavy draw from multi-GPU render nodes or overclocked CPUs. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Efficiency drops and thermal stress rise as the load approaches the maximum rated output, so continuous operation near the limit is not ideal. The unit is not for systems that regularly exceed this wattage or require redundant power modules.

ATX Interface and Form-Factor Constraints

The standard ATX footprint fits most full-tower and mid-tower cases, but the physical length may conflict with compact chassis or dense cable routing. Cabling is fixed, so unused connectors remain inside the case and can restrict airflow in tight builds. The supply relies on the motherboard's ATX 24-pin and CPU EPS connectors; builders needing server-grade hot-swap bays or non-standard pinouts must verify compatibility separately. It does not support redundant CRPS hot-plug configurations despite the supplier model codes.

Questions about this item

Will the 1600W capacity and ATX form factor support my older components that use standard 24-pin and 8-pin connectors?

Yes, the ATX form factor and 1600W output are designed to deliver power through standard connectors used by older hardware, while the DC-to-DC conversion provides stable voltage rails for legacy parts.

How can I confirm the Zero RPM fan mode is active once the system is running?

Under low or medium loads the cooling fan stops completely, so you can verify operation by listening for silence at idle and feeling for airflow only when the load increases.

Does the package include the necessary power cables, or must I buy them separately?

The unit is a CRPS-style module that slides into a compatible chassis or redundant cage; the required AC inlet and output cables are typically supplied with that enclosure rather than with the power supply itself.
