Antec SFX850GB: Powering the Future of Compact Gaming
Building a powerful PC doesn’t mean you have to build a big one. The rise of small form factor (SFF) cases has created a new challenge for enthusiasts: how to pack a top-tier CPU and GPU into a tiny chassis without compromising on power or cooling. Antec’s answer is the SFX850GB, a power supply that delivers high-wattage performance and next-generation features in a compact SFX form factor. This isn’t just an SFX PSU; it’s an ATX 3.1-compliant powerhouse designed to be the heart of your next SFF masterpiece.
The Perfect Blend of Form and Function
The Antec SFX850GB is purpose-built for the unique demands of small form factor computing. Its 850W capacity, a truly impressive figure for an SFX unit, is more than enough to handle high-end hardware, including a vast majority of the latest GPUs without issue.
SFX Form Factor: Measuring a mere 125mm x 100mm x 63.5mm, the SFX850GB is designed to fit snugly into mini-ITX and SFF cases, leaving more space for other components and improving overall airflow.
Fully Modular: In a confined space, every inch matters. The SFX850GB is fully modular, meaning you only connect the cables you need. This dramatically reduces cable clutter, making a clean build easier and allowing for better airflow within your case.
80 PLUS Gold Efficiency: With an 80 PLUS Gold certification, the SFX850GB operates at up to 92% efficiency at a 50% load. This not only reduces your energy bill but also generates less waste heat, which is a critical factor for keeping an SFF system cool and stable.
Silent Performance: The unit features a quiet 92mm fan with a Zero RPM Manager function. The fan will only spin up under heavy load, ensuring a silent computing experience during everyday tasks or light gaming.
The Antec SFX850GB is a triumph of engineering, proving that you no longer have to sacrifice power or features when building a compact PC!!

ATX 3.1 & PCIe 5.1 Ready
The SFX850GB isn’t just a powerful SFX power supply; it’s a future-proof ATX 3.1 and PCIe 5.1 compliant unit. This is the key feature that sets it apart from older models and makes it the ideal choice for modern, high-end builds.
It comes equipped with a native 12V-2×6 connector, the refined version of the 12VHPWR connector. This single, high-capacity cable is designed to power the latest graphics cards like the NVIDIA RTX 40-series, safely and without the need for cumbersome adapters. The ATX 3.1 standard also guarantees the PSU can handle the instantaneous power spikes (transient loads) of modern GPUs, ensuring your system remains stable and free from crashes during intense gaming or rendering.
