AT form-factor power supply for legacy desktop

This unit follows the AT standard and is intended for older desktop systems that require a 450 W rated supply operating at 300 W, 350 W or 400 W continuous output. It suits restorers and hobbyists maintaining vintage hardware where ATX units will not fit.

Silent operation with 300 W to 400 W continuous

The supplier describes the supply as silent, indicating low acoustic output during typical desktop workloads. Rated outputs of 300 W, 350 W and 400 W allow the builder to match the unit to the system's actual power draw without oversizing.

商品問答

How do I install the AT power supply and which connector alignment do people often get wrong?

Align the keyed AT motherboard connectors so the black wires sit side by side in the centre before pressing them in; forcing them reversed bends pins and prevents the 300 W, 350 W, 400 W or 450 W unit from powering on.

What maintenance will the 450 W AT power supply need later?

Clean the intake vents and fan blades every six to twelve months with compressed air to keep the silent desktop host supply running at its rated 300 W, 350 W, 400 W or 450 W output.
