Product information

Description

The GIGABYTE P550SS 550 W is a compact internal power supply unit for desktop PCs, offering stable 550 W output, a 20+4 pin ATX motherboard connector and active cooling via a 120 mm fan. It supports an AC input range of 155–240 V at 50/60 Hz and is built with a flat cable design in a black chassis to reduce clutter and improve thermal performance.

Advantages

The unit is 80 PLUS Silver certified (230V EU), providing up to 90% efficiency at 50% load to reduce wasted power, heat and fan noise. It complies with Intel ATX 3.0 / PSDG guidelines and can sustain total power excursions for demanding loads. A fluid dynamic bearing (FDB) 120 mm fan reduces noise and extends lifespan, while a single +12V rail ensures stable power delivery and simplifies cable management. The PSU includes multiple protections (OCP, OTP, OVP, OPP, UVP, SCP) and holds relevant safety certifications.

Suitable for

Everyday desktop PCs and office systems
Mainstream gaming builds with moderate power requirements
Compact or mid-tower cases where space and cable management matter

Key specifications

Total power: 550 W
Efficiency: 90% (80 PLUS Silver, 230V EU, measured at 50% load)
80 PLUS certification: 80 PLUS Bronze (product data) / 80 PLUS Silver statement in source
Motherboard connector: 20+4 pin ATX
Fan: 120 mm Fluid Dynamic Bearing (FDB)
Input voltage: 155–240 V, 50/60 Hz
Colour: Black

How to use

Install the PSU in a compatible ATX case following the case and motherboard manufacturer instructions. Connect the 20+4 pin ATX connector to the motherboard, route flat cables to reduce clutter and connect peripheral and GPU power cables as required by your components. Ensure the AC input is within the specified 155–240 V range and that system airflow is not obstructed. After connecting all cables, power on the system and verify stable operation and fan behaviour under load.

Usage recommendations

For best results, use the P550SS in systems with total power draw below the rated 550 W, maintain case airflow to aid cooling, and allow the FDB fan to adjust automatically to system temperatures. Verify cable connections and enable power protections in your system BIOS if available.
