Product information

Description

Seasonic CORE GC-750 ATX 3.1 is a 750 W fully modular power supply designed for modern PCs. Compliant with ATX 3.1 and PCIe 5.1 standards, it delivers 750 W total power with 100–240 V AC input at 50/60 Hz and features a 24-pin ATX motherboard connector. The unit is 80 PLUS Gold certified, comes in black, and includes a 120 mm active fan with Seasonic’s Smart and Silent Fan Control for balanced cooling and low noise. The CORE GC series uses an improved OptiSink PCB layout and automated surface-mount production to enhance reliability, thermal performance, and energy efficiency.

Advantages

The Seasonic CORE GC-750 provides high energy efficiency with its 80 PLUS Gold certification and a fully modular cable system that simplifies cable management. Its updated OptiSink design and revised PCB layout improve heat dissipation and internal airflow, resulting in cooler operating temperatures and longer component life. Native support for next‑gen and legacy GPU power via 12V-2x6 and 2×8-pin connections increases compatibility across graphics cards. A 120 mm Hydro Dynamic Bearing fan combined with S2FC (Smart and Silent Fan Control) optimizes cooling while minimizing audible noise. The product is covered by Seasonic’s 7-year worldwide manufacturer’s warranty.

Suitable for

  • Gaming desktops requiring up to 750 W continuous power
  • Workstations with discrete GPUs needing PCIe 5.1 compatibility
  • Custom PC builds where cable management and modularity are important
  • System upgrades aiming for improved efficiency and quieter operation

Key specifications

  • Total power: 750 W
  • AC input: 100–240 V, 50/60 Hz
  • Motherboard connector: 24-pin ATX
  • Certification: 80 PLUS Gold
  • Fan: 120 mm Hydro Dynamic Bearing
  • Form factor: ATX, fully modular cabling
  • Color: Black
  • Manufacturer warranty: 7 years

How to use

Install the CORE GC-750 into a compatible ATX case following the motherboard and case manufacturer instructions. Mount the power supply securely with the fan orientation that best suits your case airflow (the OptiSink design allows safe installation in either orientation). Connect the 24-pin ATX cable to the motherboard, attach CPU and PCIe connectors as required by your components, and use modular SATA/Peripheral cables for drives and peripherals. Ensure the AC cord is connected to a properly grounded outlet and check all connections before powering on the system.

Usage recommendations

For optimal performance, keep case airflow unobstructed and ensure intake/exhaust fans create a consistent flow through the power supply area. Use native PCIe connectors when possible; use the included adapters only when necessary. Periodically inspect cables and dust the 120 mm fan to maintain cooling efficiency and low noise levels.
