340W ATX Power Supply

The KHACHIMO MPW340-28A-1 is a 340W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high-efficiency operation that reduces power draw and heat. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.

Builders needing silent, efficient 340W power

This unit suits builds that prioritise quiet running and low energy consumption at modest power levels. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Systems requiring higher wattage for multi-GPU setups or heavy overclocking should look at higher-capacity units. Buyers needing modular cabling or specific connector counts not detailed here should verify compatibility before purchase.

80 PLUS Gold efficiency at 340W

The single specification that decides fit is the 340W continuous output combined with 80 PLUS Gold certified efficiency. This rating guarantees high efficiency across typical loads, lowering operating costs and thermal output. Resonant LLC topology with DC-to-DC conversion supports stable voltage regulation and enables deeper sleep states. Confirm the 340W limit meets your system’s peak power requirements before buying.

Questions sur cet article

Does the 80 PLUS Gold rating mean the fan runs quieter during all-day use?

Yes, the Gold certification indicates higher efficiency which produces less heat, so the fan can stay off longer under typical loads.

What motherboard power connectors must my system provide for this ATX unit?

A standard 24-pin ATX connector and the appropriate CPU power connector are required on the motherboard.

Will the LLC resonant topology with DC-to-DC conversion cause issues with an older motherboard?

The topology delivers clean, stable voltage regulation that is fully compatible with legacy ATX motherboards.
