GIGABYTE P550B
GIGABYTE P550B
The Gigabyte P550B PC power supply provides power to your PC components with a rated output of 550W. The design uses a single +12V rail to power the processor and graphics card. It achieves up to 85% efficiency at 50% load. The 80 PLUS Bronze certification indicates the level of energy efficiency, resulting in lower energy losses and corresponding heat production. A 120mm fan with a hydraulic bearing handles the cooling, and the power supply is equipped with a set of six protection circuits to ensure safe operation.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its wattage. This indicates the maximum number of Watts the power supply can continuously deliver to the components in your computer. It is a good idea to use a web-based calculator to work out the optimal wattage based on your chosen components.
Efficiency and quiet operation
The 80 PLUS Bronze certification sets the power supply's efficiency at approximately 85% under a 50% load. Lower energy losses correspond to less waste heat production. A 120mm fan with a hydraulic bearing handles heat dissipation, and has a stated lifespan of over 4 years. The fan speed adjusts automatically according to the current load on the power supply.
Flat cabling
All cables have a flat profile, which affects two practical aspects of building a computer. Firstly, it makes installation and cable routing easier. The flat shape of the wires can reduce the volume of cabling, thereby influencing the airflow inside the PC case. Secondly, the smaller space requirements of the cables can reduce obstructions in the airflow path, which can contribute to heat dissipation from system components.
Powerful +12V rail
The power supply uses a single +12V rail to power components with higher performance demands, such as the processor and graphics card. The single +12V rail provides a stable output and is designed for compatibility with standard modern hardware, including configurations with increased power requirements. The system's operation is secured by a set of OVP, OPP, SCP, UVP, OCP, and OTP protection circuits that react to conditions like overvoltage, overload, short circuits, or undervoltage.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of PC power supplies. This gives users a simple and clear comparison between different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC PSU load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82 % | 85 % | 82 % |
| 80 PLUS Bronze | 85 % | 88 % | 85 % |
| 80 PLUS Silver | 87 % | 90 % | 87 % |
| 80 PLUS Gold | 90 % | 92 % | 89 % |
| 80 PLUS Platinum | 92 % | 94 % | 90 % |
| 80 PLUS Titanium | 94 % | 96 % | 94 % |
