GIGABYTE P550SS 550 Watt 80+ Standard Power Supply

The GIGABYTE GP-P550SS and GP-P550SS ICE power supplies are designed to deliver efficient and reliable power for modern PC builds. Both models feature 80 PLUS Silver certification (230V EU), achieving up to 90% efficiency at typical loads, which reduces power loss, lowers heat output, and minimizes fan noise.

Compliant with Intel ATX 3.0 and compatible with ATX 3.1 standards, these units support up to 2x total power excursion. This ensures stable operation during sudden power spikes from high-performance GPUs and CPUs, making them suitable for gaming and professional workloads.

The single +12V rail design provides consistent power delivery and simplifies installation, while ensuring compatibility with a wide range of hardware configurations. The inclusion of flat, all-black cables in the standard model and color-matched cables in the ICE variant improves airflow and reduces internal clutter.

Cooling is handled by a 120mm Fluid Dynamic Bearing fan, which uses oil film technology to reduce noise and extend lifespan. The fan dynamically adjusts speed based on system load and temperature, maintaining a balance between cooling efficiency and quiet operation.

Both variants include comprehensive protection mechanisms such as OVP, OPP, SCP, UVP, OCP, and OTP, ensuring system safety under various conditions. With a high MTBF of over 100,000 hours and compliance with international safety standards, these PSUs provide dependable long-term performance. The GP-P550SS ICE variant offers identical performance in a white aesthetic, ideal for themed or white PC builds.
