KHACHIMO FAS9000 1600W ATX Power Supply

This ATX power supply delivers 1600 W of continuous power for high-end workstations and multi-GPU systems. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The unit suits builders who need reliable, high-wattage power in a standard form factor.

Thermals, noise and power draw in normal use

At low and medium loads the Zero RPM fan mode stops the cooling fan completely for near-silent operation. The 80 PLUS Gold rating means less waste heat and lower power consumption during everyday tasks. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter running. These features combine to keep the system cool and quiet under typical workloads.

Behaviour under sustained load rather than a short

Under sustained heavy loads the Resonant LLC topology with DC-to-DC conversion maintains stable, clean power delivery. The 80 PLUS Gold efficiency rating continues to limit excess heat generation during prolonged operation. Modern Standby support allows the unit to enter more energy-efficient sleep states between intense work periods. This design targets consistent performance for demanding, long-duration computing tasks.

Questions about this item

How do I install the KHACHIMO FAS9000 1600W PSU in a standard ATX case and which cable routing step is often missed?

Mount the unit using the four ATX screw holes, connect the 24-pin motherboard and 8-pin CPU cables first, then route all modular cables behind the motherboard tray before securing the side panel — builders often forget to plug in the PCIe power connectors for the graphics card until after the panel is on.

What maintenance will the DPS-1600AB-4A need over its lifetime?

The 80 PLUS Gold certified unit uses a Zero RPM fan mode at low loads; periodically clean dust from the intake grill with compressed air to keep airflow unrestricted, and replace the PSU if coil whine appears or voltages drift outside specification.

What limit appears first when the 1600W supply runs at sustained high load?

Internal component temperature rises until the protection circuitry triggers a shutdown, so adequate case airflow is essential to avoid hitting the thermal limit before the full 1600W rating can be maintained continuously.
