GP-P550SS

The Gigabyte GP-P550SS is engineered for gamers and PC builders seeking dependable and efficient power delivery for mainstream gaming PCs and desktop systems. Built around the Intel ATX 3.0 specification and compatible with ATX 3.1 standards, the PSU is designed to support modern gaming hardware and next-generation desktop platforms.

Delivering 550W of continuous output power, the GP-P550SS is ideal for mid-range gaming systems and productivity desktops. The PSU supports Intel’s modern power excursion requirements and can sustain up to 2× total power excursion loads required by modern GPUs and CPUs.

Certified with 80 PLUS Silver efficiency (230V EU), the GP-P550SS achieves up to 90% efficiency at typical load conditions, helping reduce excess heat generation, fan noise, and overall power consumption during operation.

The PSU uses a non-modular cable design with flat all-black cables to improve cable routing and internal system aesthetics. A powerful single +12V rail design improves stable power delivery to modern CPUs and graphics cards during gaming and multitasking workloads.

Cooling is handled by a quiet 120mm Fluid Dynamic Bearing fan utilizing oil-film shock absorption technology to reduce operating noise and improve long-term durability compared to conventional sleeve-bearing fans. The fan dynamically adjusts speed according to PSU temperatures and system load for quieter everyday operation.

Comprehensive protection systems including OVP, OPP, SCP, UVP, OCP, and OTP help safeguard connected hardware against electrical irregularities and unexpected operating conditions. Combining Silver-rated efficiency, modern ATX compatibility, and reliable cooling performance, the Gigabyte GP-P550SS is an excellent PSU choice for budget-conscious gaming and desktop builds.
