Product information

Description

The Chieftec GPB-350S 350 W is a compact desktop power supply unit designed for standard ATX systems. It delivers 350 W total power, provides a 20+4 pin ATX motherboard connector and operates from AC 200–240 V at 47–63 Hz. The unit uses a fixed, non-modular cable set and an active cooling solution with a 120 mm fan. Built with modern PCB design and components, it meets RoHS requirements and is offered in resource-efficient bulk packaging.

Advantages

The GPB-350S combines moderate efficiency (85%) with a competitive price and reliable components derived from CHIEFTEC's iARENA design approach. Its fixed 20+4 pin ATX connector ensures compatibility with a wide range of motherboards, while the 120 mm fan supports effective heat dissipation for sustained operation. RoHS compliance and fixed 230 V-ready design simplify deployment in regions with 200–240 V mains.

Suitable for

Office desktop PCs with standard ATX motherboards
Home computers for web browsing, media playback and light productivity
System builders seeking cost-effective, RoHS-compliant PSUs in bulk

How to use

Install the Chieftec GPB-350S into a compatible ATX case, secure it with the mounting screws and connect the 20+4 pin ATX cable to the motherboard.

Use this PSU in systems with modest power requirements up to its 350 W rating, avoid heavy overclocking or high-end graphics card combinations that exceed total output, and keep the interior of the PC free of dust to preserve cooling and component longevity.
