Ultimate Power Flexibility for High-Performance Graphics Cards

With versatile PCIe 8-pin and native 12V-2x6 connectors, the MEGA TI series delivers unmatched flexibility in power configurations.

It's perfectly suited for powering even the most demanding NVIDIA or AMD graphics cards, guaranteeing stable and reliable performance under heavy workloads.

Whether you're gaming, creating content, or tackling other intensive tasks, you can configure your system with total confidence.

FSP Interleaved PFC | Maximum Efficiency, Minimal Heat

The FSP MEGA TI series utilizes FSP Interleaved PFC, boosting efficiency up to 95% while cutting heat by 10-15°C. It reduces ripple by 50%, ensures stable power delivery, and extends component lifespan-making it the ultimate choice for high-performance systems.

Fully Modular with Embossed Cabling Design

The MEGA TI series prioritizes user convenience, offering high-quality embossed cables that are soft, flexible, and easy to install. These cables can be neatly routed to minimize clutter, making the installation process smoother and significantly improving system airflow. By using only the cables you need, you can keep your setup clean and organized, boosting both aesthetics and performance.

High Efficiency in Titanium-certified

The MEGA TI series holds the prestigious 80 PLUS® Titanium certification, awarded by globally recognized organizations.

This elite certification signifies the highest standards in energy efficiency, ensuring lower power consumption, minimal heat generation, and whisper-quiet operation.

Users can trust that their systems will run cooler, quieter, and more efficiently, contributing to a superior computing experience.

Complies with Intel Power Supply Design Guide ATX 3.1

The MEGA TI series is fully compatible with the latest ATX 3.1 standard, offering robust support for up to 200% power excursion. This ensures that even the most demanding power spikes are handled with ease.

Additionally, the inclusion of the new PCIe 12V-2x6 connector interface guarantees peak performance and seamless integration with upcoming hardware advancements, allowing users to future-proof their systems with confidence.

Whisper-Quiet Zero RPM Mode

When load levels drop below 40%, the Zero RPM mode activates when the eco semi-fanless switch is turned on. This ensures the fan remains off, providing completely silent operation and a quieter workspace. As system demands increase, the 135mm fluid dynamic bearing fan powers up, delivering efficient cooling while its durable design extends the fan's lifespan. This approach offers an ideal balance between silence and cooling performance.

Complete Protection

OVP, OCP, OPP, OTP

SCP, UVP, SIP, NLO

Featuring a comprehensive circuit protection system, meticulously designed to safeguard your valuable components from potential electrical hazards. This advanced protection system shields against overvoltage, undervoltage, overcurrent, and short circuits, ensuring that your system remains safe and operational even under extreme conditions.

Off-Wet, Off-Dust and Off-Stain

A conformal coating shields the PCB, guarding it against harsh environmental conditions. This protective layer ensures reliable, consistent performance even in extreme settings with up to 95% relative humidity.

Whether you're in a humid climate or a dusty area, you can trust your power supply to perform at its best, providing peace of mind and long-term reliability.
