EVGA 550 B5 80+ Bronze 550W Fully Modular Power Supply Key Features Fully modular power supply, with all cables being removable to reduce clutter, allow customisation, and maximise airflow A whisper-quiet 135mm fluid dynamic bearing fan 80 PLUS Bronze-certified efficiency for 85% efficiency or higher under typical loads 100% Japanese capacitors ensure long-term reliability Up to 45A on a single +12V rail Tonnes of heavy-duty protection to make sure your setup stays running at its best 5-Year warranty and support from EVGA Overview Introducing the EVGA 550 B5 power supply. It starts with the most important standard for reliability, a Japanese main capacitor. Next, a small chassis and fully modular design provide maximum flexibility. The ultra-quiet 135mm Fluid-Dynamic Bearing fan becomes silent when coupled with EVGA ECO mode to turn off the fan in medium to low loads. Last, but not least, the 550 B5 power supply has a full suite of protections and a 5-year limited warranty that you have come to know and expect from EVGA. This PSU includes a 135mm fluid dynamic bearing fan generating quieter, ultra-quiet operation and helps it last longer. With ECO mode, the fan will not spin on lower loads, meaning there is no sound at all! The fully modular design of this power supply allows any and all of your cables to be removed to help reduce clutter and improve airflow, and then add them in later if need be. Power without safety is pointless, so a full suite of top tier circuit protection is built-in, keeping you running strong and your hardware safe. These include Over and Under Voltage Protection, Over Current Protection, Over Power Protection, Over Temperature Protection, and Short Circuit Protection. This PSU features an 80 Plus certification, ensuring your power supply is not wasting power and turning it into excess heat. Under typical load, this power supply is 85% efficient or higher. Get reliable power and protection for years to come.
