ANT Esports RX550 80 Plus Bronze SMPS

The ANT Esports RX550 is a 550-watt ATX power supply unit from the brand’s RX Bronze Series, built for users who need dependable, efficient power delivery without overspending on their PC build. Holding an 80 Plus Bronze certification, the RX550 is rated to deliver up to approximately 82% energy efficiency across a range of load conditions, helping reduce wasted heat and lowering electricity draw compared to non-certified units. At the core of the RX550’s design is a single 12V rail architecture, which channels all available wattage through one unified rail. This approach is favoured for consistent, stable power delivery to the CPU, GPU, and other system components — particularly useful in mid-range gaming and productivity builds where predictable current distribution matters. The unit also incorporates Active Power Factor Correction (Active PFC), which improves compatibility with a wide variety of power sources and helps maintain stable input even when voltage fluctuates. Cooling is handled by a 120mm fan that is designed to operate quietly during normal use while still providing sufficient airflow to keep internal components within safe thermal limits, even under sustained full-load conditions. The fan is rated for up to 100,000 hours of operational lifespan, which speaks to its build quality and suitability for long-term use. Safety protections built into the RX550 include over-current protection (OCP) and over-power protection (OPP), both of which help safeguard connected components in the event of electrical anomalies or unexpected load spikes. Connectivity is well-suited to modern system configurations. The unit ships as a non-modular design, meaning all cables are hardwired to the PSU housing — a straightforward, cost-effective arrangement common in value-segment power supplies. The RX550 comes with a manufacturer warranty of 3 years.
