1100W ATX power supply for high-output builds

This unit delivers 1100 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency and lower heat output. Modern Standby compatibility ensures rapid wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion provides clean, stable power delivery.

Ideal for workstations

The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Builders who need extremely compact SFX dimensions or lower wattage for small-form-factor cases should consider other form factors. Systems with modest power requirements will not utilise the full capacity of this unit.

1100 watt continuous output decides fit

Match the combined peak draw of your CPU, graphics cards and peripherals to this 1100 watt rating. The Gold efficiency level reduces waste heat and electricity cost under typical loads. Verify that your case accepts a standard ATX power supply before purchasing.

Questions about this item

Does the KHACHIMO 1100W ATX unit fit a standard ATX case opening?

Yes, the power supply uses the standard ATX form factor so it will mount in any case designed for ATX units.

What is the installation step that first-time builders often miss with this PSU?

Connecting both the 24-pin ATX cable and the 8-pin EPS cable to the motherboard before the first boot.

When will the cooling fan on this 1100W model need attention?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so it runs less often and typically only needs dust removal after extended heavy use.
