High-wattage ATX power supply

The KHACHIMO DD352M65-1M1 delivers 3500 W of continuous power through an ATX form factor, targeting workstation builds and multi-GPU systems that demand sustained high-current output. It is not suited for compact cases or standard office PCs that require lower maximum capacity.

80 PLUS Gold efficiency and silent features

Gold certification reduces waste heat and lowers electricity draw under typical loads. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern standby sleep states.

Standard ATX installation

The unit fits regular ATX mounting points and uses conventional cable connectors, so assembly follows normal desktop build steps. Cable stiffness in high-wattage looms can make routing tight behind motherboard trays, and verifying that the case provides enough depth for the power supply body is essential before starting.

Questions about this item

Will the cooling fan need replacement after years of continuous use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear; when the fan does spin it is the only moving part that may eventually need replacement.

What is the first limit reached under sustained full-load operation?

The 3500 W rated output is the hard ceiling; exceeding it triggers over-current protection and shuts the unit down.

How much heat and noise does the unit produce when running all day at typical load?

80 PLUS Gold efficiency keeps waste heat low, and Zero RPM Fan Mode allows near-silent operation at low and medium loads; fan noise only appears at higher loads.
