Key technologies of the Seasonic Prime PX-2200 ATX 3.1 computer power supply
- 2200W power for systems with extreme loads
- 80 PLUS Platinum certification confirms high energy efficiency
- Digital Hybrid Fan Control maintains quiet fan operation
- Zero RPM mode switches the fan off under low load
- Fully modular cabling simplifies organisation inside the PC case
- Two 12V-2x6 connectors support modern graphics processing cards
Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, is power. This indicates the maximum number of watts the power supply can continuously provide to the components in the computer. It is advisable to use an online calculator to determine the optimal power based on your chosen components.
Computer power supply performance
The power supply is designed for builds with exceptional energy delivery requirements. Its power and extensive range of connectors are sufficient for reliable operation of systems equipped with multiple graphics cards. Builds for AI calculations, professional rendering or data analysis will benefit from its ability to power up to four RTX 4090 cards simultaneously without compromising on stability and performance.
Seasonic Prime PX-2200 power supply standards
This 2200W computer power supply fully complies with ATX 3.1 and PCIe 5.1 specifications. This enables it to efficiently manage even very high transient power spikes generated by modern graphics cards under sudden load. Thanks to the native 12V-2x6 connectors, you can safely connect modern graphics accelerators and other components that require this power standard.
High efficiency and precise regulation
The 80 PLUS Platinum certification confirms high energy efficiency, reaching 92% at 50% load. This reduces energy losses through conversion to heat and limits overall running costs. Micro Tolerance Load Regulation technology maintains the output voltage with a deviation of less than 1%, which contributes to greater stability and protection of sensitive components.
Computer power supply cooling
Heat dissipation is handled by a 135mm fan with a fluid dynamic bearing, which reduces friction and noise, and extends its lifespan. The Digital Hybrid Fan Control system actively adjusts the speed according to the current load and temperature. In addition, the Zero RPM mode switches the fan off completely at low loads, transitioning to completely silent passive operation.
Fully modular cabling and connectivity
This 2200W modular power supply offers fully detachable cables, which simplify installation and cable management inside the case. You only connect the cables you actually need. This solution improves airflow and simplifies system maintenance. The connector set includes two 16-pin 12V-2x6 connectors, eighteen SATA and three CPU connectors.
Comprehensive set of protections
The Seasonic power supply integrates a complete set of protections that shield connected components from damage in case of abnormal operating conditions. These include protection against overvoltage, undervoltage, overcurrent and overload. Also included is protection against short circuits and overheating, contributing to safe and reliable operation.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies, giving users a simple and clear way to compare different models. In the European market (which uses a 230V voltage), there are six levels of 80 Plus certification, each with specific requirements for power supplies. Higher energy efficiency primarily means lower energy consumption.
