300W Fan-Free AT Power Supply

This AT-form-factor power supply delivers 300 watts of continuous power without any moving parts. The fan-free design eliminates mechanical noise completely, making it suitable for silent workstations or noise-sensitive environments. It fits standard AT desktop chassis and provides the connectors required by legacy motherboards and peripherals.

Silent Operation for Legacy AT Systems

The unit produces no fan noise because it relies solely on passive cooling, so it cannot serve builds that need active airflow across the power supply itself. Buyers who require a cooling fan for higher thermal loads or modern ATX motherboard connectors should look elsewhere.

商品問答

What does the 300W rating mean for a real desktop build?

It indicates the maximum continuous power the unit can deliver to ATX components under normal loads.

What interface standard does this supply use and what does it limit?

It uses the AT form factor, so it fits older AT-style cases and motherboards rather than modern ATX layouts.
