400 W ATX V2.0 power supply

This unit delivers 400 W of continuous power through the ATX V2.0 standard and is suited for office desktops or basic home builds that require a straightforward replacement. It uses a 12 V rail design with a 12 cm fan for airflow.

Thermals and noise

The 12 cm fan moves air across the internal components to manage heat during typical workloads. Acoustic output remains low enough for quiet environments while the supply draws only what the connected hardware demands.

Questions about this item

How is the 400 W ATX V2.0 unit installed and which cable connection is often missed?

Slide the supply into the case, secure it with four screws, attach the 20+4 pin main connector and the 4-pin CPU power lead, then plug in the IEC mains cord.

What maintenance will the 12 cm fan need over time?

Blow dust from the fan blades and grille every few months; if the bearing becomes noisy, replace the entire 400 W power supply.
