Antec GSK 850W 80 Plus Gold ATX 3.1 PCIe 5.1 White Full Modular Power Supply:
The Antec GSK 850W 80 Plus Gold ATX 3.1 PCIe 5.1 White Full Modular Power Supply is a cutting-edge solution designed for high-performance gaming and professional systems. It combines advanced features with premium build quality, making it an excellent choice for modern PC builds. With full compatibility for ATX 3.1 and PCIe 5.1 standards, this PSU ensures seamless performance and future-proof connectivity, especially for the latest NVIDIA® GeForce RTX™ 40 Series GPUs via its dedicated 12VHPWR (12V-2×6) cable. The 80 PLUS Gold certification guarantees up to 90% energy efficiency, which helps reduce power waste and keeps your system running cooler and quieter.
Key Features for Enhanced Performance and Reliability:
At the core of the GSK 850W is Antec’s innovative PhaseWave™ Design, a server-class LLC topology that incorporates synchronous rectification and DC-DC conversion. This design ensures unparalleled stability and highly efficient power delivery to all your components. The power supply is equipped with high-quality Japanese capacitors, which contribute to extremely tight voltage regulation and minimal ripple, maximizing your system’s overall performance and longevity.
Cooling is managed by a whisper-quiet 120mm fluid-dynamic bearing (FDB) silent fan, known for its exceptional durability and quiet operation. The Zero RPM Manager further enhances thermal efficiency by activating the fan only when necessary, providing near-silent operation during low loads. The fully modular design allows for precise cable management, eliminating clutter and improving airflow within your PC chassis.
Safety is a top priority, and the GSK 850W comes with Antec’s comprehensive CircuitShield™ suite of industrial-grade protections. These include OCP (Over Current Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), SCP (Short Circuit Protection), OPP (Over Power Protection), OTP (Over Temperature Protection), SIP (Surge & Inrush Protection), and NLO (No Load Operation), safeguarding your valuable components in any operating environment. Its compact size ensures compatibility with a wide range of PC cases, making it a versatile and reliable choice for your next build.
