## Long description

The Antec GSK ATX3.1 850W is a fully modular power supply unit designed for gaming and enthusiast PC builds. It delivers up to 850 W of continuous power with 80 PLUS Gold efficiency and supports ATX 3.1 and PCIe 5.1 standards. The unit includes a 120 mm fluid-dynamic bearing fan, high-quality JP capacitors, PhaseWave™ DC-DC topology with synchronous rectification, and a range of industrial-grade protections for stable and reliable operation.
Advantages
The PSU combines ATX 3.1 and PCIe 5.1 compatibility with tight voltage regulation from JP capacitors and a PhaseWave™ design to provide consistent, low-noise power delivery. Its 80 PLUS Gold certification ensures high efficiency, while the Zero RPM Manager and 120 mm FDB fan offer quiet, temperature-driven cooling. The fully modular cable design simplifies cable management and improves airflow within the case.
Suitable for
High-performance gaming PCs using modern GPUs (PCIe 5.1 compatible)
Content creation and workstation builds requiring stable 850 W power
Enthusiast systems where cable management and quiet operation matter

How to use
Install the power supply into a compatible ATX case following the case manufacturer’s instructions and connect the 20+4 pin ATX cable to the motherboard. Use the provided modular cables for GPU, SATA, and peripheral connections, routing only the cables required to minimize clutter. Ensure the AC input matches the local mains specification (100–240 V, 50/60 Hz) and secure the PSU with the mounting screws supplied with your case. After initial power-on, verify system stability and monitor fan behavior; the Zero RPM Manager will keep the fan idle until thermal thresholds require activation.
Usage recommendations
For optimal performance and longevity, keep internal case airflow unobstructed, use only the necessary modular cables, and place the PSU in a well-ventilated environment. When installing high-end GPUs from recent generations (for example NVIDIA GeForce RTX 40 series), use the supplied PCIe 5.1-compatible cable. Regularly check connections and clean dust from the fan and vents to maintain cooling efficiency.
