The Antec GSK 850W PCIe 5.1 Gen5 80 PLUS Gold Fully Modular Power Supply combines cutting-edge technology with premium build quality, making it a top-tier choice for gamers and professionals. With ATX 3.1 and PCIe 5.1 compatibility, this PSU ensures seamless performance for modern systems, including support for NVIDIA® GeForce RTX™ 40 Series GPUs via its 12VHPWR 12V-2×6 cable. Featuring 80 PLUS Gold certification, it delivers up to 90% energy efficiency, reducing power waste and keeping your system cooler and quieter during operation. The fully modular design allows for precise cable management, eliminating clutter and improving airflow.
At the heart of the GSK 850W is its PhaseWave™ Design, a server-class LLC topology with synchronous rectification and DC-DC conversion that guarantees unparalleled stability and efficient power delivery. The power supply is equipped with high-quality Japanese capacitors, ensuring tight voltage regulation and minimal ripple for enhanced system performance and longevity. Safety is paramount, and the CircuitShield™ suite of protections—including OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO—safeguards your components in any operating environment.
Cooling is handled by a 120mm fluid-dynamic bearing (FDB) silent fan, renowned for its durability and quiet operation. The Zero RPM Manager enhances thermal efficiency by activating the fan only when needed, offering near-silent operation during low loads. Compact and versatile, the GSK 850W is designed to fit a wide range of cases while providing exceptional reliability, efficiency, and ease of use.
