Gigabyte says it's created the world’s first water-cooled external GPU using Nvidia’s new RTX 3000 graphics cards. 

The Aorus RTX Gaming Box contains the RTX 3090 or the RTX 3080 inside a large case that can be carried around and connected to a laptop or desktop PC. Once plugged in, the box can then feed graphics data over a Thunderbolt 3 connection for gaming or 3D animation workloads. 

The product appears to be a refresh of last year’s Aorus Gaming Box, an 8-pound unit that contained Nvidia’s older RTX 2080 Ti card. It currently retails for an insane $2,272. But for the high price, you’re getting an external GPU that’s not only portable, but also promises to run silently, thanks to the all-in-one Aorus Waterforce cooling system inside.

“We take care of not only the GPU but also the VRAM and MOSFET to ensure a stable operation and longer life,” the company said in the announcement. Specifically, the cooling system uses a large copper plate, a 240mm aluminum radiator and two 120mm fans, along with a pump and water block, for efficient cooling and a low noise level. 

The company is hoping to sell the product to laptop users seeking to transform their computers into heavy-duty gaming machines. The box also contains some RGB lighting, which can be configured by installing the company’s software on your PC. 

We reached out to Gigabyte on when the external GPU will be available and for what price, and will update the story if we hear back.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
