Product information

Description

The Chieftec GPB-400S 400W is a fixed 230V desktop power supply unit designed for reliable everyday PC use. It delivers 400 W of total power with an 85% efficiency rating, a standard 20+4 pin ATX motherboard connector and a single 120 mm cooling fan.

Its 85% efficiency supports reasonable energy use, and the fixed 230V operation with wide frequency compatibility (47–63 Hz) suits standard European mains. The included 120 mm fan ensures consistent cooling and the compact form factor fits most standard enclosures.
