What this product is

The KHACHIMO HF800W-S-110 is an 800W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification and supports Modern Standby for fast wake times and improved low-load efficiency. A resonant LLC topology with DC-to-DC conversion delivers clean power and helps reduce coil whine.

Who this suits and who should look elsewhere

Builders who value quiet operation benefit from a Zero RPM fan mode that stops the fan at low and medium loads. Systems requiring 110V input at 7A are matched by the rated specification. Buyers needing a higher total wattage or a different input voltage range should look at other units.

The specification that decides fit

The 800W continuous rating is the single figure that determines whether this unit can power your chosen components. Verify that your full-system load stays within this limit before purchasing.
