If you're on the lookout for a new power supply unit for a mainstream to even high-end PC, Seasonic is a brand you shouldn't miss out on, especially with its mainstream-oriented Focus GX ATX 3.1 line-up of power supply units (PSUs).
First launched back in September 2024 and available in 1000W, 850W and 750W variants, the Focus GX line-up is in its fourth iteration till date, where the current model is also known as the Focus V4 in certain quarters. Featuring a fully-modular design with 80PLUS Gold and Cybernetics Platinum certification (for the 850W and 750W variants - the 1000W variant has Cybernetics Gold certification instead), the Focus GX ATX 3.1 also boasts bells and whistles such as a fan-less operation mode (Digital Hybrid Fan Control) and Seasonic's OptiSink technology, which is in reference to a new PCB design that utilises smaller MOSFET and heatsink components, thereby creating more space within the PSU for heat dissipation, leading to cooler operation temperatures, better efficiency and improved reliability. Watch on to learn more about this PSU as ALKtech unboxes the black-coloured 850W variant of the Focus GX ATX 3.1!
