The Seasonic G12 GM power supply is a reliable and highly efficient ATX solution with a power reserve of 850 W and an 80+ Gold quality certificate. It is a representative of the mid-range Seasonic G12 series, which includes relatively simple, affordable and high-quality power supplies with a modern element base and a “smart” cooling system. According to the manufacturer, it is the best option for powering gaming PCs and mid- to advanced-level workstations.

It is ideal for gamers and professionals who are looking for a highly efficient, reliable and durable power supply (5-year warranty) without having to overpay for minor details like built-in backlighting. The circuitry of the model uses a resonant LLC converter and a Smart and Silent Fan Control (S2FC) fan control system with intelligent thermal control. The efficiency of the device is at around 90% and fully meets the requirements of the 80+ Gold class.

Inside, there are heat-resistant capacitors, DC-DC converters and resonant LLC converters, and the main 12-volt line is capable of delivering almost 100% of the power. The cooling system consists of one 120-mm fan with a sleeve bearing. The semi-modular cable layout includes 24+8+8(4+4) pin for powering the motherboard and processor, 6 SATA connectors, 3 MOLEX connectors and 3 PCI-E 8pin (6+2) connectors.
