The Antec GSK1000 AU is a high-performance, full-modular power supply engineered to meet the demands of modern gaming rigs and enthusiast PCs. Delivering a reliable 1000W output with impressive 80 PLUS Gold efficiency, this PSU ensures stable and efficient power delivery while minimizing energy waste.

Built to the ATX 12V 3.1 standard, it supports the latest PCIe 5.1 12V-2x6 GPU connectors for cutting-edge graphics cards and offers extensive connectivity options including multiple CPU, PCIe, SATA, and Molex connectors. The unit features an advanced PhaseWave design combining server-grade LLC topology with synchronous rectification and DC-DC conversion, promising precise voltage regulation with minimal ripple and improved reliability.

Cooling is conveniently managed by a 120mm fluid dynamic bearing (FDB) silent fan equipped with Zero RPM Manager technology. The fan remains off during light loads for silent operation and activates under heavy use to prevent overheating. Its compact dimensions (140 x 150 x 86 mm) improve case compatibility and airflow.

Safety is paramount with CircuitShield protections covering over-current, over-voltage, under-voltage, short circuit, over-power, over-temperature, surge, and noise limitations. The PSU is compliant with multiple global safety and electromagnetic certifications and comes backed by a 10-year warranty, reflecting its lasting durability and quality.

Key features include full modularity for neat cable management, active power factor correction (PFC), wide input voltage support (100–240V AC), and multiple connector options to support a wide array of system configurations.
