Product information

Description

The Antec GSK ATX3.1 750W is a high-efficiency power supply unit designed for modern desktop systems. Delivering 750 W of continuous power, this PSU supports ATX 3.1 platforms and includes a 20+4 pin ATX motherboard connector. It accepts AC input from 100–240 V and features an 80 PLUS Gold efficiency rating to reduce energy loss and heat under typical loads. The unit uses a 120 mm fluid-dynamic bearing fan and an active cooling system for controlled thermal management while maintaining compact dimensions and a black finish.

Advantages

The Antec GSK ATX3.1 750W combines ATX 3.1 and PCIe 5.1 compatibility with server-grade topologies and high-quality JP capacitors to deliver stable voltage regulation and low ripple. PhaseWave design and full modular cabling offer efficient power delivery and flexible cable management. A 120 mm FDB silent fan together with Zero RPM Manager reduces noise and prolongs component life, while comprehensive CircuitShield protections safeguard the system from common electrical faults.

Suitable for

  • Gaming PCs with mid to high-end graphics cards
  • Workstations requiring stable continuous power
  • System builds that need compact, modular PSUs for better cable management
  • Upgrades to ATX 3.1 / PCIe 5.1 compatible systems

Key specifications

  • Total power output: 750 W
  • Motherboard connector: 20+4 pin ATX
  • Efficiency certification: 80 PLUS Gold
  • Cooling: 120 mm fluid-dynamic bearing fan with Zero RPM Manager
  • Input voltage: 100–240 V AC
  • Modularity: Full modular cable design
  • Protections: Over current, over voltage, under voltage, short circuit and other industrial-grade protections
  • Colour: Black
  • Weight: 2.52 kg

How to use

Install the Antec GSK ATX3.1 750W into a compatible desktop case following standard PSU mounting procedures, securing it with the supplied screws and connecting the 20+4 pin ATX connector to the motherboard. Attach required modular cables only (SATA, PCIe, CPU) to the PSU ports to minimize clutter. Ensure the AC mains cable is rated for your region and connect to a grounded outlet. Verify fan operation and consult the motherboard and GPU manuals for correct PCIe power connector usage.

Usage recommendations

For reliable operation, position the PSU so its fan intake is unobstructed and maintain adequate case airflow. Use only the necessary modular cables to improve airflow and lower temperatures. Keep firmware and system drivers up to date when installing high-power GPUs to ensure stable power draw management.
