ATX Power Supply for Efficient Builds

This 350W ATX power supply suits system builders who want certified efficiency and quiet operation in a standard desktop chassis. It targets everyday computing and office workloads where low power draw and reliable wake-from-sleep behaviour matter more than high-end graphics headroom. The unit is new and ready for integration into compatible ATX systems.

Gold-Certified Efficiency with Silent Fan

80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and lowering overall power consumption. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion delivers clean power and minimises coil whine. Modern Standby compatibility enables extremely fast wake times and improved low-load efficiency.

350W Capacity Defines the Use Case

The 350W rated output is the single figure that determines whether this unit fits a given build; it supports mainstream CPUs and integrated graphics or modest discrete cards, but cannot sustain high-power components or multi-GPU configurations. Builders needing more headroom for demanding graphics cards or heavy overclocking must select a higher-wattage model. Compatibility rests on matching the ATX form factor and the required connector set to the motherboard and components.

Questions about this item

What ATX standard does the 350 W unit follow, and what does that cap in practice?

The power supply uses the ATX form factor, which limits it to standard ATX case mounting points and the usual 24-pin, CPU, and peripheral connector set.

What physical clearance and mounting pattern does the supply need to fit?

It requires a standard ATX mounting cut-out and the depth allowance of a typical ATX chassis; no proprietary brackets or extra screw holes are used.

How is the PSU installed, and which step is most often missed?

Secure the unit with four case screws, connect the 24-pin motherboard and CPU power cables, then enable Modern Standby in the BIOS so the fast wake and low-load efficiency features actually activate.
