Your Mac or Windows PC Will Never Be the Same
Transform MacBook Pro, MacBook Air, Mac mini, iMac, or any Thunderbolt 3 equipped Windows PC into a high-end graphics processing workstation. The OWC Mercury Helios FX 650 eGPU comes ready to have the GPU of your choice installed. With support built into the latest macOS and Windows 10, adding graphics processing power is as simple as plugging the Mercury Helios FX 650 into your computer's Thunderbolt 3 port.

WORK FASTER. PLAY FASTER.
Modern software and operating systems utilize the massive power housed in the GPU to enhance the performance that spans nearly everything you do. And nowhere is GPU realized more than with graphics intensive programs, video editing suites and VR/AR software. With the graphics processing possibilities of the Mercury Helios FX 650 combined with your choice of GPU, you can experience shorter rendering times and faster effects operations with Final Cut Pro, DaVinci Resolve, Avid, Adobe, and other video suites.

All that extra speed empowers you to iterate and experiment more. Allowing you to push that latest edit to the next level, or journey on a different path to see where it takes your creative vision.

When you need to take a break from work, the same horsepower delivers incredible gaming graphics and higher FPS at higher resolutions. With full support for Apple Metal as well as OpenGL/CL, there's no limit to what you can accomplish and experience.

LOOK ELSEWHERE FOR PLANNED OBSOLESCENCE
Unlike other eGPUs, the Mercury Helios FX 650 is upgradeable. When the time comes for a better GPU, we made upgrading super simple so you can reuse your investment for years to come. That’s better for you, and produces much less e-waste. The high power capabilities will let you run the demanding GPUs of today and tomorrow. The chassis is made of recyclable materials as well, which makes the Mercury Helios FX 650 the smart upgradeable and recyclable choice.

DESIGNED FOR EXCELLENCE
Keeping this much graphics processing power cool and quiet is a tall order, but Mercury Helios FX 650 delivers. With a large variable speed, temperature-controlled fan, the Mercury Helios FX 650 plays nicely even in the most noise-sensitive environments. Minimal noise is only part of the equation. Reducing the number of cables going into your computer combines to create a clean and distraction free workspace. The Mercury Helios FX 650 provides up to 100W of power to a connected notebook computer, freeing up a Thunderbolt 3 port and letting you keep your power adapter in your bag for life on the move.

TURBO BOOST EVEN THE LATEST MODELS
The latest computer models, even those with discrete GPUs, can experience a performance boost with the Mercury Helios FX 650. With more dedicated memory, more processing cores, and higher clock speeds, this external GPU can take your computer further.
