Power supply unit Fortron FSP MEGA-1000GM 1000 W ATX 80 PLUS Gold fully-modular black, 135 mm fan

The Fortron FSP MEGA-1000GM is a 1000 W ATX power supply unit with 80 PLUS Gold efficiency and a fully modular cable system. Compliant with Intel ATX 3.1 design guidelines, the unit supports modern power delivery requirements including support for PCIe 12V-2x6 connectors and high peak power excursions. The compact 150 x 150 x 86 mm chassis houses a 135 mm fluid-dynamic bearing fan with eco semi-fanless control, high-grade 105°C Japanese bulk capacitors, and a single powerful +12V rail designed for contemporary CPUs and graphics cards.

Advantages

The MEGA-1000GM delivers high conversion efficiency (approximately 90% typical) that reduces power loss and heat generation while complying with 80 PLUS Gold / Cybenetics Gold certification standards. Its fully-modular embossed cable design simplifies installation and cable management, improving system airflow. FSP MTLC® (Micro Tolerance Load Control) ensures tight load regulation (±1%) for stable voltage delivery under dynamic loads, supporting demanding AI, rendering, and gaming workloads. Built-in protections (OCP, OVP, SCP, OPP, UVP, OTP, SIP, NLP) and conformal coating improve reliability in challenging environments.

Suitable for (tasks / use cases)

• High-performance gaming desktops with power-hungry graphics cards
• Workstations for 3D rendering, video editing, and AI workloads
• Systems requiring compact ATX form factor with strong power delivery
• Custom builds where cable management and airflow are priorities

How to use

Install the MEGA-1000GM into a compatible ATX case, secure it in the PSU bay, and connect only the necessary modular cables to the motherboard, CPU and graphics card power inputs. Use the native PCIe 12V-2x6 connector or standard PCIe 8-pin connectors according to your graphics card requirements. Set the eco semi-fanless switch to enable zero-RPM operation under light loads if quieter operation is desired. Ensure the system chassis has adequate airflow and that connectors are fully seated before powering the system for the first time.

Usage recommendations

For stable operation, pair this PSU with high-efficiency components and maintain case airflow. Use the fully-modular cables to minimize clutter and avoid routing cables across airflow paths. For maximum longevity, operate the unit within recommended ambient temperature ranges and periodically inspect connectors and dust buildup around the fan.
