KHACHIMO R840 ATX Gold Power Supply

The KHACHIMO R840 is an ATX power supply certified to 80 PLUS Gold efficiency. It is built for desktop systems that demand stable delivery and reduced energy waste during daily workloads.

Modern Standby and Zero RPM Features

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation while the resonant LLC topology with DC-to-DC conversion reduces coil whine.

Ideal for Quiet Efficiency-Focused Builds

This unit suits builders who prioritise quiet operation and high efficiency in a standard ATX form factor. It is not for systems requiring server-grade redundancy or specialised form factors such as SFX or TFX.

Domande su questo articolo

How often will the internal fan bearings need replacement on the R840?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, so bearing wear accumulates much more slowly than on a unit that spins constantly.

What limit appears first when the R840 runs at high output for hours?

With 80 PLUS Gold efficiency the power lost as heat becomes the practical ceiling, and the fan will ramp up to manage those temperatures.

How much noise and heat does the R840 produce during an all-day workload?

At typical loads the Zero RPM mode keeps the fan off for silent operation, while Gold-rated efficiency minimises waste heat even when the fan eventually spins.
