GIGABYTE P550SS ICE
GIGABYTE P550SS ICE
The Gigabyte P550SS ICE computer power supply delivers stable power to PC builds in the standard ATX format. Its total output of 550W is aimed at mid-range systems that require reliability and efficiency. The 80 PLUS Silver certification confirms a high efficiency of 90%, which limits energy waste and heat production. Full compatibility with the ATX 3.1 standard reliably covers the power demands of modern components, including the ability to handle sudden power spikes. The overall appearance in Ice White complements builds focused on a uniform and clean aesthetic.

Key technologies of the Gigabyte P550SS ICE computer power supply
- Power supply output of 550W
- 80 PLUS Silver certification confirming up to 90% efficiency
- ATX 3.1 standard handles power spikes up to twice the total output
- The fan uses a fluid dynamic bearing
- A single powerful +12V rail supplies stable current to high-performance components
- Flat cables make in-case organisation easier and improve airflow
Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the format, is the power output. This indicates the maximum number of Watts the power supply can continuously supply to the components in the computer. It's a good idea to use a web-based calculator to work out the optimal power output based on your chosen components.
High efficiency with 80 PLUS Silver certification
The 80 PLUS Silver certification confirms that the power supply achieves 90% efficiency at 50% load. This means less electrical energy is converted into waste heat. Reduced heat production directly contributes to quieter operation, as it results in a lower operating temperature for the power supply, allowing the fan to run at lower speeds. The lower energy consumption also has a positive effect on running costs.
ATX 3.1 support
Full compliance with the Intel ATX 3.0 specification, compatible with the more modern 3.1 version, prepares your build for the demands of current and future components. The power supply can withstand short-term power spikes of up to twice its rated output. This capability prevents system instability during sudden power draws, which are typical for powerful graphics cards and processors under intensive load, such as gaming or rendering.
Quiet and efficient cooling
A 120mm fan equipped with a fluid dynamic bearing (FDB) handles the dissipation of heat from the internal components. Unlike standard sleeve bearings, it uses oil film technology to dampen vibrations and reduce friction, leading to significantly quieter operation and an extended operational life. Additionally, the fan speed automatically adjusts to the current load and temperature of the power supply, optimising the balance between cooling performance and noise level.
Stable power supply
The single powerful +12V rail design delivers a stable and consistent current to key components like the processor and graphics card. This approach eliminates the need to split the load across multiple rails and is suitable for overclocking. The firmly attached cables have a flat profile, which simplifies cable management and promotes a clean build appearance. They also restrict airflow in the case less, contributing to more efficient cooling of the entire system.
Comprehensive protection
The power supply integrates a set of six key protection mechanisms that safeguard the connected hardware from damage. The integrated protection circuits continuously monitor key electrical parameters and provide protection against overvoltage, overload, short circuit, undervoltage, overcurrent, and overheating, thereby protecting the entire system. In the event that non-standard operating conditions are detected, the power supply will immediately cut the power.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for computer 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% |
