ANT ESPORTS FP550B 550W 80+ Bronze Non Modular ATX 2.0 Power Supply

The Ant Esports FP550B is a 550-watt ATX 2.0 power supply carrying the 80 Plus Bronze efficiency certification, meaning it delivers at least 82% efficiency at 20% load, 85% at 50% load, and 82% at 100% load under standard 115 V AC conditions. It is a non-modular unit with a fixed cable harness featuring black flat cables that simplify routing and airflow management inside the chassis. The FP550B is built around a single 12V rail design, which consolidates all 12V current to one rail and can reduce nuisance over-current shutdowns on high-draw components such as modern discrete GPUs. The unit ships with a comprehensive protection suite covering over-voltage protection (OVP), over-power protection (OPP), short-circuit protection (SCP), under-voltage protection (UVP), over-current protection (OCP), and over-temperature protection (OTP), helping guard connected components against electrical anomalies. Cooling is handled by a 120mm hydraulic bearing (HYB) fan. Hydraulic bearing fans offer quieter operation compared to sleeve bearing alternatives and are rated for up to 100,000 hours of operational life according to the manufacturer. The PSU also incorporates automatic load detection: the fan modulates or halts under lighter system loads, further reducing acoustic output during everyday tasks. Ant Esports backs the FP550B with a 3-year manufacturer warranty, providing added purchase confidence for budget and mid-range system builders. The unit is compatible with standard ATX mid-tower and full-tower chassis.
