KHACHIMO 700W ATX Power Supply

This 700 watt ATX power supply carries an 80 PLUS Gold certification for high efficiency across typical loads. It features a resonant LLC topology with DC-to-DC conversion that delivers clean, consistent power and reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suited for efficient and quiet ATX builds

Builders who prioritise low noise and high efficiency in a standard ATX form factor will benefit from the Gold-rated platform and fan-stop behaviour. Systems that require power levels above 700 watts or a different form factor such as SFX should look elsewhere. The unit is designed for typical desktop workloads and Modern Standby sleep states rather than sustained extreme loads.

700 watt 80 PLUS Gold ATX capacity

The single specification that decides fit is the 700 watt continuous output with 80 PLUS Gold efficiency in an ATX form factor. If your build demands more than 700 watts or a smaller chassis standard, this unit will not meet the requirement. For standard ATX systems targeting high efficiency and quiet operation at this power level, the rating is the decisive figure.

Questions about this item

How do I install this ATX power supply and what step is often missed?

Mount the unit in the case with the four screws, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature works.

What maintenance will this power supply need later?

The Zero RPM fan mode stops the fan at low load, so dust accumulates more slowly; clean the intake grill with compressed air when you see visible buildup.

What limit appears first under sustained heavy load?

The 700 W maximum output is the first limit; continuous draw above that trips the over-power protection and shuts the unit down.
