FSP today introduced its new MEGA GM Series of fully modular power supplies, available in 850W, 1000W, and 1200W models. Engineered for gamers, creators, and high-performance PC users, the MEGA GM combines premium build quality, Gold-rated efficiency, and full compliance with the latest Intel ATX 3.1 and PCIe 5.1 standards.
Gold Efficiency with Cybenetics A++ Certification
The FSP MEGA GM Series is certified with both 80 PLUS Gold and Cybenetics Gold and A++ ratings, achieving over 90% efficiency at typical loads. This dual certification ensures lower energy loss, reduced heat output, and quieter operation under all conditions.
Next-Gen Ready for NVIDIA & AMD GPUs
Equipped with a native PCIe 12V-2×6 connector alongside multiple PCIe 8-pin connectors, the MEGA GM Series is fully compatible with the latest NVIDIA GeForce RTX 50 Series and AMD Radeon graphics cards. The units support up to 200% power excursion, guaranteeing stable and reliable performance even during intense gaming or rendering workloads.
Advanced Power Control with FSP MTLC
The series integrates FSP’s proprietary MTLC (Micro Tolerance Load Control) design, achieving ultra-precise voltage regulation within ±1%, far exceeding ATX 3.1 requirements. This technology ensures exceptional stability for CPUs and GPUs, improving efficiency and extending component lifespan.
Compact and Whisper-Quiet
Each unit features a 135 mm Fluid Dynamic Bearing (FDB) fan with Eco semi-fanless mode, achieving whisper-quiet operation below 15 dB(A) — certified Cybenetics Lambda A++, one of the highest acoustic performance ratings available. The fan stays off during light loads under 50% and ramps up smoothly under heavy use, delivering reliable cooling with minimal noise.
Measuring just 150 × 150 × 86 mm, the MEGA GM fits easily into compact chassis without compromising power output or stability.
Fully Modular & Protected
A fully modular embossed cable design allows for clean builds and improved airflow. Comprehensive safety protections — OCP, OVP, SCP, OPP, UVP, OTP, SIP, and NLO — safeguard the system from damage under abnormal conditions. In addition, FSP’s exclusive Off-Wet, Off-Dust, and Off-Stain conformal coating provides enhanced resistance to humidity, dust, and environmental corrosion, ensuring long-term stability and reliability even under challenging conditions.
