Seasonic X-850 850W Power Supply, Active PFC Certified, Gold Certification

The Seasonic X-850 is a high-performance power supply designed for demanding computer systems, particularly those with high-end components such as powerful CPUs, GPUs, and multiple storage drives. It is certified with 80 Plus Gold, indicating that it achieves at least 87% efficiency at typical loads, which helps reduce energy consumption and heat output. The power supply features an active power factor correction (PFC) system with a typical power factor of 99%, ensuring efficient use of electrical power and reducing strain on the electrical grid. It also includes a DC-to-DC converter design, which enhances voltage stability and reduces noise. The unit is equipped with conductive polymer aluminum solid electrolytic capacitors, which are known for their durability and long lifespan. The full modular cabling design allows for easy installation and improved airflow within the PC case, while the honeycomb structure in the ventilation system ensures effective cooling. The Seasonic X-850 is compatible with a wide range of input voltages (100–264V) and frequencies (50/60 Hz), making it suitable for use in various regions around the world. It also includes a hybrid silent fan control system that adjusts fan speed based on temperature, minimizing noise during low-load operation. The power supply comes with a 5-year warranty, reflecting Seasonic's confidence in its product quality.

The Seasonic X-850 is equipped with an integrated voltage regulator module (VRM), which ensures stable and clean power delivery to the CPU and other components. This is particularly beneficial for systems that require precise voltage regulation for optimal performance and stability. The all-in-one DC cabling design simplifies the setup process by providing pre-connected cables for essential components, while the modular design allows users to connect only the cables they need, reducing clutter inside the PC case. The power supply also includes an easy-swap connector feature, which makes it simple to replace or reconfigure components without having to disconnect all cables.

The Seasonic X-850 is designed to handle high loads efficiently, with a total power output of 850 watts. This makes it ideal for high-performance gaming PCs, workstations, and systems with multiple high-power components. The unit's input current range of 10–5A ensures compatibility with a wide range of power sources and electrical configurations.
