KHACHIMO 800W ATX Power Supply

This 800W ATX power supply is built for desktop systems that demand efficient and quiet power delivery. It carries 80 PLUS Gold certification and features Modern Standby compatibility for fast wake times. The unit uses a resonant LLC topology with DC-to-DC conversion to provide clean, stable output. It suits builders assembling new workstations or upgrading existing ATX chassis.

Ideal for quiet-focused builds

The zero RPM fan mode keeps operation near-silent at low and medium loads, making it a strong choice for noise-sensitive environments. Gold-rated efficiency reduces waste heat and lowers running costs over time. Builders who need higher wattage for multi-GPU configurations or extreme overclocking should consider higher-capacity units instead. Systems requiring SFX or TFX form factors cannot use this ATX unit.

800W ATX with 80 PLUS Gold and zero RPM mode

The single specification that decides fit is the 800W ATX rating combined with 80 PLUS Gold efficiency and a zero RPM fan mode. This combination delivers enough power for mainstream high-performance builds while staying silent during everyday tasks. Verify that your case accepts a standard ATX power supply and that your components' total draw stays within the 800W limit.

Questions about this item

Will this 800W ATX unit fit a standard ATX chassis?

Yes, the ATX form factor matches standard mounting holes and depth for most desktop cases.

How do I connect the cables and what is the common mistake?

Plug the 24-pin ATX, CPU and GPU cables firmly until they click; the step often missed is leaving the 24-pin partially seated, which prevents boot.

Which part will need replacement first on this 800W supply?

The internal cooling fan is the only moving component; its bearings typically wear out after several years of continuous use.
