Chieftec GPB-400S 400W - PSU, 80 Plus Bronze

The Chieftec GPB-400S is a 400-watt power supply unit designed for standard ATX desktop systems. It operates with an 80 PLUS Bronze certification, achieving up to 85% efficiency under typical load conditions to reduce wasted energy. The inclusion of Active Power Factor Correction (PFC) supports stable power delivery and meets required electrical efficiency standards. As a non-modular PSU, all cables are permanently attached, which is a common configuration for straightforward system builds where custom cable management is not a primary requirement.

This unit is cooled by a single 120 mm fan designed to regulate internal temperatures during operation. It adheres to the ATX 2.3 specification, ensuring compatibility with a wide range of motherboards and components. The PSU is equipped with a comprehensive set of protection circuits, including over-voltage (OVP), overload (OPP), under-voltage (UVP), and short-circuit (SCP) protection. These features function to safeguard the power supply and connected system hardware from potential electrical faults.
