Τροφοδοτικό GIGABYTE P550SS – PCIe 5.0, 80 PLUS Silver, 120mm GP-P650SS EU

The GIGABYTE P650SS 650 W is a PC power supply unit that delivers stable power for desktop builds. It supports the ATX 3.0 standard and Intel PSDG requirements, features a single +12V rail and flat cables to reduce clutter, and uses a 120 mm fluid dynamic bearing fan for quieter operation. The unit includes multiple built-in protections (OCP, OTP, OVP, OPP, UVP, SCP) and has international safety certifications.

Advantages

80 PLUS Silver certification (230V EU) provides up to 90% efficiency at 50% load, lowering energy loss and heat. The ATX 3.0 compatibility allows for sustained power excursions and compliance with Intel PSDG timing and low-load efficiency requirements. A 120 mm fluid dynamic bearing fan reduces noise and extends lifespan, while the single +12V rail ensures stable power delivery and simple cable management. Flat cables improve internal airflow and installation neatness. Comprehensive protection circuits safeguard system components.

Suitable for

• Home and office desktop PCs requiring a reliable 650 W PSU
• Gaming or workstation builds needing stable single-rail +12V output
• Systems that benefit from reduced cable clutter and improved internal airflow
• Builds that follow ATX 3.0 and Intel PSDG power excursion requirements

Key specifications

• Total power: 650 W
• 80 PLUS certification: 80 PLUS Silver (230V EU)
• Motherboard connector: 20+4 pin ATX
• Fan diameter: 120 mm (Fluid Dynamic Bearing)
• Cooling: active, automatic fan speed control based on load and temperature
• Form factor / size: compact unit (manufacturer dimensions in product data)
• Protection features: OCP, OTP, OVP, OPP, UVP, SCP

How to use

Install the PSU into a compatible ATX case following standard safety procedures: disconnect mains power, mount the unit securely, connect the 20+4 pin ATX motherboard connector and other required peripheral connectors (SATA, PCIe, CPU) to your components. Ensure cables are routed to avoid obstructing airflow and confirm all connections before powering on. The fan will automatically adjust speed according to power draw and temperature.

Recommendations

Use this PSU in systems with total component power draw comfortably below 650 W to maintain efficiency and headroom for peak power excursions. Keep intake and exhaust paths clear and use the flat cables to improve case airflow. Verify that your build components and connectors are compatible with a single +12V rail design.
