350W ATX power supply for modern standby systems

This 350W ATX unit is built for desktops that use modern standby sleep states. It delivers reliable power for everyday computing and office workloads. The design targets builders who want efficient low-load behaviour without oversizing the power supply.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC design paired with DC-to-DC conversion supplies clean, consistent voltage to components. This topology reduces coil whine and supports deeper, more energy efficient sleep states. An 80 PLUS Gold rating confirms high efficiency across typical loads, lowering heat output and fan noise.

Zero RPM fan mode at low and medium loads

The cooling fan stops completely during light workloads for near-silent operation. At higher loads the fan spins up to maintain safe temperatures. Buyers needing more than 350W for multi-GPU setups or heavy overclocking should select a higher capacity unit.

Questions about this item

Does the ATX power supply meet the 80 PLUS Gold efficiency standard in practice?

Yes, the unit is 80 PLUS Gold certified, meaning it delivers high efficiency across typical loads for lower power draw and less heat.

What physical space and mounting points does this 350W ATX unit require?

It uses the standard ATX form factor, so it fits any case with an ATX PSU bay and four rear mounting screws.

How is the PSU installed and which step do builders often miss?

Mount the unit, connect the 24-pin motherboard and 4/8-pin CPU cables, then route power to drives and GPU; the step often missed is plugging in the CPU power cable near the socket.
