NZXT PA-8G2BB-US C850 Gold ATX 3.1 Fully Modular PSU 850W

The NZXT C850 Gold (PA-8G2BB-US) is a fully modular 850W power supply built to the ATX 3.1 standard, making it a forward-looking choice for modern gaming PC builds. Its headline feature is the native 12V-2x6 connector, which can deliver up to 600W to compatible NVIDIA GeForce RTX 40 Series graphics cards through a single clean cable — no adapters required. With 80 PLUS Gold certification, it operates at high efficiency across a range of loads, keeping energy waste and heat generation to a minimum.

Inside, the C850 Gold relies on 100% Japanese capacitors for dependable voltage regulation and long-term durability. Cooling comes from a 135mm fluid dynamic bearing fan that operates in Zero Fan Mode below 50% load, meaning the PSU remains completely silent during typical gaming sessions and everyday use. The fully modular cable design lets builders use only the cables they need, simplifying cable management and improving case airflow. Finished in black and designed to complement NZXT's ecosystem of cases and components, the C850 Gold is a well-rounded PSU for anyone building a high-performance system that values clean aesthetics and quiet operation.
