Antec ATOM B550 550W Power Supply

The Antec ATOM B550 is a 550W non-modular power supply that delivers stable and efficient power for mid-range PC builds. Certified with 80 Plus Bronze, it offers good energy efficiency, making it suitable for general computing and light gaming systems.

Power and Performance

• Maximum Power Output: 550W – Adequate for mid-range systems, such as general use PCs or systems with a single graphics card.
• Efficiency Rating: 80 Plus Bronze – Provides a minimum of 82% efficiency at 20% load, 85% at 50%, and 82% at 100% load, reducing energy consumption and improving stability.
• Efficiency: Unspecified, but the 80 Plus Bronze rating suggests decent energy savings.
• PFC (Power Factor Correction): Unmentioned – While this is typically included in modern PSUs, it's not specified here.

Protection Features

• Over Voltage Protection (OVP): Yes – Protects against dangerous voltage surges that could damage the components.
• Over Power Protection (OPP): Yes – Prevents damage if the PSU is overloaded.
• Over Current Protection (OCP): Unmentioned – Lack of explicit OCP means there's a potential risk for damage under high-current conditions.
• Over Temperature Protection (OTP): No – There's no direct thermal protection in this model.
• Short Circuit Protection (SCP): Yes – Ensures the PSU shuts down in the event of a short circuit.
• Under Voltage Protection (UVP): Yes – Shuts down the PSU if the input voltage is too low, preventing instability.
