The Antec SF850X is a high-performance, compact power supply designed for small-form-factor gaming PCs and high-end builds requiring efficient and stable power delivery. Rated at 850W continuous output with 80 PLUS Gold certification, it ensures energy-efficient operation and lower heat generation. This PSU adheres to the latest ATX 3.1 (SFX 4.1) standard and supports PCIe 5.1, supplying modern graphics cards like the RTX 4090/5090 and Radeon XTX 7900/8900X with reliable power through its 12VHPWR cable.

The SF850X features full modular cabling, allowing for simplified cable management and a clean build. Equipped with high-quality Japanese capacitors, it delivers improved voltage regulation and longevity. Cooling is optimized via a 92mm silent fan with an intelligent Zero RPM Manager — the fan remains off during low load for silent operation and activates only when required.

Safety is paramount with Antec’s CircuitShield™ protection suite covering OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO, ensuring your components stay secure under varying conditions. The PSU’s compact dimensions (100 x 125 x 63.5 mm) make it ideal for cramped spaces without compromising functionality.

Included connectors support a wide range of devices: a 24-pin motherboard, one 16-pin PCIe 5.1 12VHPWR GPU cable, dual 8-pin EPS CPU connectors, four 8-pin PCIe connectors, six SATA power ports, and two Molex connectors. The SF850X operates safely from 0 to 40°C with universal AC input (100–240V).

Backed by a 7-year warranty and comprehensive certifications including cTUVus, TUV, CB, RCM, CE, FCC, BIS, BSMI, KC, UKCA, ICES, and CCC, the Antec SF850X ensures long-lasting reliability and peace of mind for high-demand gaming or workstation systems.
