350W AT power supply for basic desktops

This 350W AT unit is built for low-energy, low-noise desktop systems and ships with a US plug. It delivers rated output of 350W and supports manual 115/230V input switching for flexible deployment. The supply meets Intel ATX12V 2.31 specification with a double magnetic ring design and operates at over 80% efficiency.

Straightforward installation with marked connectors

Clearly labelled connectors make installation quick and effective, while a 1.1m power cord provides reach inside standard chassis. The 12cm fan is thermally controlled for automatic speed regulation. Note that the unit uses manual voltage selection without active PFC, so the switch must be set correctly before powering on.

Suits entry-level AT builds, not high-power systems

This supply suits builders assembling basic AT desktops needing 20+4 pin motherboard power, dual 4-pin CPU connectors, three SATA drives and a 6+2 pin graphics connector. It will not suit systems requiring active PFC, higher wattage headroom or modern ATX12V versions beyond 2.31.

Questions about this item

How can I verify the 350W AT unit is running correctly after I install it?

The built-in thermal sensor controls the 12 cm fan speed automatically; listen for quiet operation and check that the system stays powered under load.

What comes in the box and what must I source separately?

The package includes the power supply and a 1.1 m power cable; mounting screws and any extra SATA or GPU cables are not included.

Which voltage setting should I select for my region?

Use the manual 115/230 V switch — set it to 115 V for North America or 230 V for most other regions before plugging in.
