Antec GSK 850W 80 Plus Gold ATX 3.1 PCIe 5.1 Full Modular Power Supply:
The Antec GSK 850W 80 Plus Gold ATX 3.1 PCIe 5.1 Full Modular Power Supply is a high-performance power supply unit (PSU) designed to meet the demands of modern gaming and enthusiast PC builds. It combines cutting-edge standards with premium components to ensure stable, efficient, and reliable power delivery.
Key Features for Optimal Performance and Reliability:
The GSK 850W is formally certified for ATX 3.1 compliance and features PCIe 5.1 compatibility, including a native 12V-2×6 GPU cable. This ensures seamless integration with the latest graphics cards, such as the NVIDIA GeForce RTX 40 Series, providing the necessary power and stability for next-generation components.
With 80 PLUS Gold certification, this PSU delivers up to 90% energy efficiency under typical loads, reducing power waste, lowering electricity bills, and contributing to a cooler and quieter system. The fully modular design allows users to connect only the necessary cables, eliminating clutter and improving airflow within the PC case for enhanced cooling performance.
At its core, the GSK 850W utilizes high-quality Japanese capacitors, which ensure tight voltage regulation and minimal ripple and noise, maximizing system performance and longevity. The PhaseWave™ Design, a server-class LLC topology with synchronous rectification and DC-DC conversion, guarantees unparalleled stability and efficient power delivery.
Cooling is managed by a 120mm fluid-dynamic bearing (FDB) silent fan, known for its durability and quiet operation. The Zero RPM Manager feature activates the fan only when necessary, providing near-silent operation during low loads and extending the fan’s lifespan. The comprehensive CircuitShield™ suite of industrial-grade protections (including OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO) safeguards your components against various electrical anomalies, ensuring the safety and reliability of your system in any operating environment.
The GSK 850W comes in a compact size (140mm length), making it compatible with a wider range of computer cases. It is backed by a 7-year warranty, providing long-term peace of mind.
