Gigabyte P550SS 550W Silver

The Gigabyte P550SS 550W Silver is a high-performance, cost-effective power supply unit designed for system builders, gamers, and professionals seeking stability and energy efficiency. Engineered with 80 PLUS Silver certification, it ensures up to 88% energy efficiency at typical loads—reducing energy waste and lowering system heat output.

Built with 100% high-quality Japanese capacitors, the P550SS offers enhanced reliability and longer operational lifespan, even under high loads. The single +12V rail design ensures consistent power delivery to all components, making it ideal for modern GPUs and processors.

It features flat black cables, which not only improve airflow within the chassis but also provide a cleaner, more organized build appearance. The 120mm hydraulic bearing fan delivers efficient cooling with minimal noise, adapting speed according to system load.

The P550SS also includes multiple protection circuits (OCP, OVP, UVP, OPP, SCP, OTP) to safeguard your components against electrical faults and instabilities.
