350 W ATX Power Supply

The KHACHIMO 350W ATX unit delivers 80 PLUS Gold certified efficiency for lower power draw and reduced heat. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Upgrade from lower-efficiency or noisy units

This supply replaces older power supplies that lack Gold-rated efficiency or produce audible fan noise at idle. The jump is worthwhile when building or refreshing a system that uses Modern Standby sleep states and benefits from silent, low-load operation. The resonant LLC design with DC-to-DC conversion also suits users sensitive to coil whine who want cleaner power delivery without increasing wattage headroom.

Check ATX fit and connector needs

Verify that your chassis accepts a standard ATX form-factor power supply before ordering. Confirm the included cable set provides the motherboard, CPU and peripheral connectors required by your specific components. Ensure the 350 W continuous rating meets the total power demand of your build under load. Buyers needing higher wattage for multi-GPU configurations or extreme overclocking should consider a higher-capacity model.

Questions about this item

Does the YM-6351NAR fit a standard ATX case?

Yes, it uses the standard ATX form factor so it mounts in any case with an ATX power-supply bay.

Which cables must be connected during installation, and which step is often missed?

Connect the 24-pin ATX and 4/8-pin CPU cables; the step often missed is plugging in the PCIe power connectors required by the graphics card.

What maintenance does the 80 PLUS Gold unit need over its life?

Clean dust from the fan intake periodically; the Zero RPM mode means the fan runs less, but dust still builds up and can raise temperatures.
