The Chieftec Core BBS-500S is a 500W power supply unit designed for systems requiring stable and efficient power delivery. It holds an 80 PLUS Gold certification, indicating a high level of energy efficiency that minimizes wasted heat and electricity consumption. Built on the ATX 12V 2.3 standard, it is compatible with a wide range of motherboards and components. With a compact depth of only 140mm, this PSU fits into standard ATX cases while allowing for more room for cable management or other hardware.
Cooling is handled by a 120mm fan that utilizes Automatic Fan Speed Control (AFC) to adjust its rotational speed based on the system's load and temperature. This unit employs a non-modular cable design, where all necessary cables are permanently attached to the housing. The motherboard and CPU power cables extend to 650mm in length, providing sufficient reach for clean routing in various case layouts. A comprehensive suite of protection circuits, including Over Power Protection (OPP), Over Voltage Protection (OVP), and Short Circuit Protection (SCP), is integrated to safeguard connected hardware from electrical faults.
