The Seasonic G12 GM-850 is an ATX power supply unit that provides 850 watts of continuous power for desktop systems. It holds an 80 PLUS Gold certification, indicating up to 90% power efficiency under typical load conditions, which helps reduce heat generation and energy consumption. The unit is engineered to deliver stable voltage regulation for modern processors and graphics cards. Its integrated Active Power Factor Correction (PFC) promotes a clean and efficient power draw from the wall outlet.
This model features a semi-modular cabling system, where essential motherboard and CPU cables are fixed while all peripheral cables are detachable. This design simplifies installation and allows for improved airflow by reducing cable clutter inside the chassis. Cooling is managed by a 120mm fan equipped with a smart control system that adjusts rotational speed according to the thermal load, balancing effective cooling with low noise output. The PSU's standard 140mm depth ensures compatibility with most ATX-compliant cases.
