Fuente de alimentación CHIEFTEC GPB-350S 350 W, ATX 2.3, 20+4 Pin, ventilador de 120 mm, 85 % de eficiencia

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
