What efficiency rating does the Seasonic G12 GM (2024) 850W hold?

The G12 GM 850W is 80 PLUS Gold certified, ensuring high power efficiency of up to 90% at 50% system load, which helps reduce energy consumption and heat generation.

Does the G12 GM 850W use a fully modular or semi-modular cabling design?

It features a semi-modular design. The essential motherboard and CPU cables are attached, while peripheral and PCIe cables are detachable, allowing for cleaner cable management than non-modular units.

What fan technology does Seasonic use in the G12 GM series?

The PSU uses Seasonic’s Smart and Silent Fan Control (S2FC), an intelligent thermal circuit that ensures efficient component cooling while maintaining the quietest possible operation, primarily by controlling a 120mm sleeve bearing fan.

High Efficiency and Quiet Cooling in the Seasonic G12 GM 850W PSU

80 PLUS Gold Certified Efficiency

To begin with, the G12 GM 850W is engineered to meet the stringent 80 PLUS Gold standard, achieving up to 90% power efficiency at optimal load levels. Consequently, this high level of efficiency minimizes wasted heat and lowers energy costs over time. Furthermore, the unit features an advanced LLC resonant converter design and Active Power Factor Correction (PFC) for exceptionally stable voltage output and enhanced reliability.

Semi-Modular Design and Smart Fan Control

Furthermore, the semi-modular cabling reduces clutter by allowing peripheral and extra PCIe cables to be removed if not needed, while the most essential cables (24-pin MB, 8-pin CPU) remain attached for stability. In addition, the Seasonic Smart and Silent Fan Control (S2FC) intelligently manages the 120mm sleeve bearing fan speed. Consequently, this system strikes the optimal balance between effectively cooling the PSU components and ensuring the quietest possible operation under various load conditions.

💡 Pro Tip:

Since the G12 GM 850W is semi-modular, take advantage of its flat black modular cables (PCIe, SATA, Molex). Only connect the cables you absolutely need to your components. This minimizes cable bulk in your case, which improves internal airflow and makes cable management significantly easier than with a non-modular unit.
