550W Bronze PSU

Gigabyte P550B 550W 80 Plus Bronze Power Supply

550W Bronze PSU from GIGABYTE is designed for desktop computers, home systems, office PCs, and entry-to-mid-range gaming builds that require reliable power delivery and practical energy efficiency. The Gigabyte P550B combines a 550-watt output with 80 PLUS Bronze certification, a 120mm Hydraulic Bearing cooling fan, flat all-black cables, and a powerful single +12V rail. This makes it a practical choice for users who want stable everyday performance without moving to a larger or more expensive power supply than their system requires.

The 550W output provides useful capacity for systems using mainstream processors, dedicated graphics cards, SSDs, hard drives, cooling fans, and common desktop accessories. It is suitable for users building a balanced gaming PC, office workstation, study computer, or multimedia system where stable power and efficient operation are important.

550W Bronze PSU with Efficient Power Delivery

The 550W Bronze PSU carries an 80 PLUS Bronze certification. GIGABYTE specifies approximately 85% efficiency at 50% load, which helps reduce wasted electrical energy and unnecessary heat generation during normal operation. Higher efficiency can also reduce the amount of cooling required inside the PSU and help keep operating noise under control. :contentReference[oaicite:1]{index=1}

This level of efficiency makes the P550B suitable for everyday gaming, office applications, internet browsing, multimedia, productivity, and general desktop use where users want a dependable balance between power consumption and performance.

120mm Hydraulic Bearing Cooling Fan

The P550B uses a 120mm Hydraulic Bearing fan designed to provide effective airflow while maintaining reliable long-term operation. GIGABYTE highlights the fan design as a quieter solution than many basic cooling mechanisms and states that the Hydraulic Bearing fan is designed for extended service life. :contentReference[oaicite:2]{index=2}

The cooling system helps remove heat generated by the internal components when the computer is under load, supporting stable power delivery during gaming, productivity, or prolonged desktop use.

Flat All-Black Cable Design

GIGABYTE equips the P550B with flat all-black cables. This cable design helps reduce clutter inside compatible PC cases and makes routing cables behind the motherboard tray easier.

Cleaner cable management can improve the appearance of a PC build and can also help airflow by reducing unnecessary cable obstruction around case fans and other cooling areas. :contentReference[oaicite:3]{index=3}

Single +12V Rail

The power supply uses a single +12V rail configuration designed to provide stable power to important components such as the processor and graphics card. A strong +12V rail is particularly useful in desktop systems where CPUs and dedicated graphics hardware can require significant power during heavy workloads. :contentReference[oaicite:4]{index=4}

Useful Connectivity for Desktop Builds

The P550B provides one 20+4-pin motherboard connector, one CPU/EPS 4+4-pin connector, two PCIe 6+2-pin connectors, six SATA connectors, and additional peripheral connections. This gives users enough flexibility for many mainstream desktop systems with dedicated graphics cards, multiple storage devices, and common PC accessories. :contentReference[oaicite:5]{index=5}

Compact ATX Design

The unit measures approximately 150 × 140 × 86mm, giving it a compact ATX form factor that fits a wide range of compatible desktop and gaming cases. The relatively short 140mm depth can leave additional internal room for storage cages, cable routing, and airflow management. :contentReference[oaicite:6]{index=6}

Wide Input Voltage Support

The Gigabyte P550B supports an input voltage range of 100–240V AC and uses Active PFC. This helps provide flexible compatibility across different electrical environments while maintaining stable conversion for supported desktop systems. :contentReference[oaicite:7]{index=7}

Comprehensive Protection Features

GIGABYTE includes multiple protection systems in the P550B, including Over Voltage Protection, Over Power Protection, Short Circuit Protection, Under Voltage Protection, Over Current Protection, and Over Temperature Protection. These safeguards help protect both the PSU and connected PC components from common electrical problems. :contentReference[oaicite:8]{index=8}

Reliable Choice for Everyday PC Builds

If you need a 550W Bronze PSU that combines 80 PLUS Bronze efficiency, a 120mm Hydraulic Bearing fan, flat black cables, a compact ATX design, a single +12V rail, and multiple electrical protections, the Gigabyte P550B provides a practical foundation for gaming PCs, office systems, home computers, and everyday desktop builds.
