KHACHIMO 1600W ATX power supply 80 PLUS Gold

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.
