Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the components in the computer. It is advisable to use a web calculator to determine the optimal wattage based on your chosen components.
High efficiency and power stability
The 80 PLUS Platinum certification means the power supply operates with up to 92% efficiency. This leads to reduced electricity consumption and less waste heat production. The fully digital platform ensures precise real-time voltage regulation, which reduces the risk of coil whine and contributes to quieter overall operation. The internal components use Japanese 105°C-rated electrolytic capacitors.
Silent operation
Cooling is handled by a 140mm fan with a fluid dynamic bearing, which offers low noise and a long lifespan. Under low and medium loads, the fan remains completely switched off thanks to the Zero RPM feature. Thermal regulation automatically adjusts the fan speed to the current temperature and load, so the power supply remains quiet even at higher outputs. This reduces distracting noise during normal work or gaming.
Flexible cabling
The fully modular cabling system makes installation and cable management inside the computer case easier. You only connect the cables you actually need, which improves airflow. The connector set includes two modern 12V-2x6 16-pin connectors for powering high-performance graphics cards. EPS/CPU, PCI-E, SATA, and Molex connectors are also available to connect all other components.
Software control with Corsair iCUE
Integration with CORSAIR iCUE software gives the user control over the power supply's operation. In the application, you can monitor the current power, temperature, and efficiency in real time. The software also lets you manually set the fan speed curve and switch between single or multiple 12V rail modes according to your preference. The power supply supports the Modern Standby sleep mode, which speeds up system wake-up from inactivity.

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. In 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 power supply 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% |
