Description

Description

The Seasonic Power Supply 850W G12-GM-850 is a top-tier PSU that demonstrates exceptional quality and efficiency. With the 80 PLUS Gold certification, it is the ultimate tool in the power supply sector, ensuring reliability and performance for your computer system.

This PSU is part of the renowned G12 GM series, specifically designed to meet the modern demands of computing technology. Its semi-modular design allows for easy cable management, reducing clutter and improving airflow within the system.

Main Features:
  • Capacity: 850W
  • Efficiency Rating: 80 PLUS Gold
  • Form Factor: ATX
  • Semi-Modular Connectivity
  • Cooling Control with Smart and Silent Fan

Designed for flexibility and high performance, the G12 GM-850 includes multiple connectors to support various components:

  • 1 x 24-pin ATX12V-2.x motherboard power connector
  • 2 x 8-pin CPU power connectors
  • 4 x PCI Express power connectors
  • 6 x SATA power connectors
  • 3 x Molex power connectors

This power supply is not just about power; it is built with advanced safety features such as Over Voltage Protection (OVP) and Short Circuit Protection (SCP), ensuring a safe computing experience. Additionally, the fan operates in hybrid mode, activating only when necessary for optimal cooling without noise.

80 Plus Gold

The G12 GM achieves 80 PLUS® Gold certification with 90% efficiency at 50% system load.

Protection Technologies

  • OPP (Over Power Protection); Function that shuts down the power supply when excessive power is drawn, generally between 110 and 140% of the advertised power.
  • OCP (Over Current Protection): Protects connected devices from excessive current.
  • OVP (Over Voltage Protection): Over voltage protection works similarly to UVP, but in the opposite way.
  • SCP (Short Circuit Protection): Short circuit protection measures the resistance on each rail and will shut down when the resistance is lower than 0.1 Ω. Generally, this is combined with OPP, OCP, OVP, and UVP.

    The product arrived quickly and in excellent packaging. I replaced the 550 W power supply because there are many accessories in the PC, such as several hard drives, a PCI TV card, desk lighting, and overall a heavy load. I found every cable I needed in the packaging. The power supply is completely silent in operation.
