810W ATX Power Supply

The KHACHIMO M1W-2810V delivers 810W of continuous power in a standard ATX form factor. It targets desktop builders who need reliable energy delivery for mid-range to high-end components. Modern Standby compatibility ensures rapid wake times and improved efficiency during low-power states.

80 PLUS Gold Efficiency and Zero RPM Fan

Certified 80 PLUS Gold efficiency reduces power draw, heat output and operating noise under typical loads. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltage while further lowering acoustic noise.

Replaces Lower Efficiency or Noisier Units

This unit upgrades older power supplies that lack Gold-rated efficiency or semi-passive cooling. The jump is worthwhile when building a Modern Standby system or when coil whine and fan noise are primary concerns. It is not for installations requiring power output above 810W.

Questions about this item

How do I install this 810W ATX unit and what step is often missed?

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

What maintenance or replacement will this power supply need later?

The Zero RPM fan mode keeps the fan off at low loads, reducing wear, but dust should be blown out of the intake annually; the fan itself is the only moving part that may eventually need replacement.

What limit appears first under sustained heavy load on this 810W model?

The 80 PLUS Gold efficiency target of 80 percent at typical loads means waste heat rises as output climbs; once internal temperatures exceed the fan curve threshold the fan spins up, marking the practical sustained-output ceiling.
