The perfectly coordinated third generation electronics offer high-precision load regulation with a tolerance of only half a percent.

The Seasonic Prime GX-850 power supply at a glance:
- 850-watt power supply with a powerful 70-amp single -ail
- Very high efficiency thanks to 80 PLUS Gold certificate
- Precise load regulation with 0.5% tolerance
- Quiet 135 mm fan with semi-passive mode
- Fully modular cable management with flat cables
- Six 6 + 2-pin PCIe connectors for graphics cards

Power supply unit with 80 PLUS gold efficiency and a strong 70 A single-rail
The Seasonic Prime GX-850 is a powerful power supply and with its 850 watts total output power also supplies high-end gaming PCs with plenty of power. The powerful 12 volt rail delivers a whopping 70 amperes and is also certified with 80 PLUS Gold. Seasonic consistently relies on high-quality electronic components and the internal connections are largely wireless.

The completely modular, individually attachable cables ensure a tidy interior and an optimized airflow. In addition to one 24-pin and two 4 + 4-pin cables, the Seasonic Prime GX-850 also provides six 6 + 2-pin PCIe connectors, 14 SATA and five 4-pin Molex connectors. With this variety of connections, high-performance systems can be implemented. Visually, the black power supply with black-silver grill fits perfectly into any housing.

Customizable fan control with semi-passive mode
The built-in 135 millimeter fan has a smooth-running fluid dynamic bearing, which ensures smooth running during operation and a long service life. The hybrid switch on the back of the power supply can also be used to switch between automatic fan control with and without semi-passive mode. This is particularly noticeable in the noise development and the maximum possible cooling capacity, depending on how much the power supply is currently being used.

It is almost unnecessary to mention that the Prime GX power supplies have all the necessary protective circuits that modern high-end models should offer. The load regulation operates with an extremely low voltage tolerance of 0.5%. Seasonic also grants a full twelve-year manufacturer's warranty.
