KHACHIMO 350W ATX Power Supply

The KHACHIMO 350W ATX power supply delivers 350 watts of continuous power for desktop builds that prioritise efficiency and quiet operation. It suits office workstations, compact home PCs and upgrades where a lower-wattage unit is required. Builders who need higher output for multi-GPU configurations or heavy overclocking should look elsewhere.

80 PLUS Gold Thermals and Noise

80 PLUS Gold certification means the unit runs with high efficiency, reducing waste heat and lowering overall power draw during normal use. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation for everyday tasks. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and keeps temperatures in check.

Modern Standby and Power Topology

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for supported systems. The resonant LLC design with DC-to-DC conversion supplies clean, consistent power while allowing more energy-efficient sleep states. No additional cables or software utilities are mentioned in the specifications.

Questions about this item

How do I install the ATX power supply in my case and which cable routing mistake should I avoid?

Mount the unit with the fan facing the case vent, connect the 24-pin ATX and CPU power cables firmly, and route cables behind the motherboard tray so the Zero RPM fan sensor is not blocked by loose wiring.

What maintenance will this 350W unit need over its lifetime?

Clean dust from the fan grill every six to twelve months; the 80 PLUS Gold efficiency and Zero RPM mode reduce heat stress, so no internal component replacement is scheduled.

At what sustained load does the fan spin up and become audible?

The Zero RPM mode keeps the fan off at low and medium loads; it starts spinning only when the load rises above the medium threshold, which is the first audible limit under sustained use.
