Power supply Gigabyte GP-P550B 550W 80+ Bronze PSU

Gigabyte GP-P550B is an ATX power supply with a power of 550W and 80+ Bronze certification, aimed at budget and mid-range gaming and office configurations. You get a standard size power supply in black, which easily fits into most ATX cases with a length of only 140 mm. With efficiency up to 85% and Active PFC, you have a more stable power supply and less loss under load. This is a PSU that comfortably covers a mid-range graphics card and a modern CPU without paying for excess power.

What you get

With 550W, you have enough headroom for a 6- or 8-core CPU plus one more serious graphics card, without entering risky zones under normal gaming load. Thanks to 80+ Bronze and up to 85% efficiency, less energy is lost as heat, which also reflects on a quieter operation of the system. Active PFC helps for a more stable power supply during fluctuations in the network (100–240V), which is important if your computer runs all day. With a rich set of connectors, you can attach several SSDs/HDDs, optical drives, or other devices, plus enough PCI-e connectors for a smoother power supply to the GPU.

• Power of 550W, suitable for a strong GPU and modern multi-core CPU in a mid-range gaming or work configuration.
• 80+ Bronze certification and up to 85% efficiency, which means less loss and lower consumption in typical gaming or office scenarios.
• Active PFC for better power factor and more stable behavior with incoming voltage from 100~240V, useful in unstable power supply situations.
• Rich set of connectors: PCI-e 6+2 Pin x 4 for graphics cards, SATA x 6 for SSDs/HDDs, and Peripheral 4 Pin x 3 + Floppy 4 Pin x 1 for older or specific devices.
• M/B 20+4 Pin and CPU 4+4 Pin connectors ensure compatibility with mainstream motherboards and processors in today's systems.
• Compact ATX format with dimensions 150 x 140 x 86 mm and a length of only 140 mm, which facilitates cable management and installation in tighter cases.
• MTBF 100,000 hours at 25°C and 36 months warranty, giving you peace of mind for long-term use in a standard environment.

Who it is suitable for

This power supply is a good foundation for a budget or mid-range gaming build, office machine, or home PC where you seek a balance between price and reliability. It is suitable if you plan for one graphics card and do not need an ultra high-end component that requires a massive PSU. If you are aiming for extreme overclocking or multi-GPU scenarios, it is better to go for higher power and a higher class certification.

The combination of 550W, 80+ Bronze efficiency, Active PFC, and a rich set of connectors makes Gigabyte GP-P550B a fair choice for a stable, everyday configuration without unnecessary extras.
