ASRock Challenger CL-550B 550W - PSU, 80 Plus Bronze

The ASRock Challenger CL-550B is an ATX power supply unit engineered to deliver 550 watts of continuous power. It is 80 PLUS Bronze certified, which specifies a minimum of 80% efficiency under typical load conditions, reducing wasted heat and energy consumption. Built to the ATX 2.52 standard with dimensions of 150 x 140 x 86 mm, it is designed for compatibility with most standard PC cases. The unit is intended for computer systems that require a stable and consistent power source for their components.

Internal thermals are managed by a 120mm fan that adjusts its speed based on the load to provide necessary cooling. A comprehensive suite of protection circuits is integrated, including Over Power Protection (OPP), Over Voltage Protection (OVP), and Short Circuit Protection (SCP) to safeguard connected hardware from electrical faults. The power supply uses flat cables, which can aid in cable management and promote better airflow within a chassis. The unit has a mean time between failures (MTBF) rating of 100,000 hours, indicating its design for long-term operation.
