350W ATX Power Supply for Modern Standby Systems

This ATX power supply delivers 350W of continuous power for desktop PCs that support Modern Standby sleep states. It targets builders who need efficient, low-noise operation in standard form-factor chassis. The unit carries 80 PLUS Gold certification for high efficiency across typical loads.

Gold-Certified Efficiency with Zero RPM Fan Mode

Resonant LLC topology combined with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. At low and medium loads the cooling fan stops completely, enabling near-silent operation during everyday tasks. The Gold rating means less waste heat and lower overall power draw.

Limits of a 350W ATX Design

The 350W rating restricts this unit to systems with modest total power demands; high-end discrete graphics cards or heavily overclocked CPUs will exceed its capacity. Builders planning multi-GPU configurations or extreme overclocking need a higher-wattage platform. The ATX form factor fits standard cases but offers no redundant or hot-swap capability.

Questions about this item

Does the 80 PLUS Gold rating guarantee a specific efficiency level at full 350W load?

The 80 PLUS Gold certification ensures high efficiency across typical loads, lowering power draw, heat, and fan noise during operation.

What physical clearance does this ATX unit require inside the BUBALUS chassis?

It uses the standard ATX form factor designed to fit the BUBALUS case without modification or adapter brackets.

How is the unit secured in the BUBALUS case, and what mounting error should I avoid?

Fasten the four rear screws evenly; forcing one corner first can misalign the threads and damage the case mounting points.
