Razer’s Core X V2 eGPU enters the Thunderbolt 5 era—but cuts corners
Razer is kicking off the Thunderbolt 5 era with the launch of the Core X V2 external GPU enclosure and a new high-end Thunderbolt 5 dock. But while the new hardware looks future-ready on paper, the practical compromises may leave longtime fans of Razer’s eGPU ecosystem underwhelmed.
The original Core X, which debuted during the Thunderbolt 3 generation, became a popular solution thanks to its built-in 650W power supply, support for large three-slot GPUs, and integrated ports like USB and Ethernet. The Core X V2, however, takes a less generous approach. Although it now accommodates larger four-slot GPUs—a boon for users of beefy modern graphics cards—it strips out several conveniences from previous models.
For starters, Razer no longer includes a power supply in the box. Users must supply both the graphics card and an ATX PSU capable of meeting the card’s needs plus an extra 230W overhead. That additional wattage is required to power the enclosure itself and deliver up to 140W passthrough charging to a connected laptop, per the Thunderbolt 5 spec.
The omissions don’t stop there. Unlike the original Core X, the V2 lacks built-in USB ports or Ethernet. Those hoping for a single-cable desktop solution are nudged toward purchasing Razer’s new Thunderbolt 5 dock—available in Mercury White for $389.99 or the RGB-laden Chroma edition for $399.99. This add-on pushes the total build cost for a functional eGPU solution even higher.
Physically, the Core X V2 is built to handle power-hungry, oversized GPUs. Measuring 16.59 x 7.76 x 8.51 inches, the enclosure is constructed with a ventilated steel chassis and includes a 120mm fan for cooling. But despite its upgraded internals and roomier design, the $349.99 base price feels steep, especially when you consider that the original Core X launched at $299 with a PSU.
Adding to the conundrum is the current state of Thunderbolt 5 adoption. Support is limited primarily to high-end gaming laptops—systems that already feature powerful discrete GPUs. That makes the “entry-level laptop, high-end eGPU” scenario less practical in the short term.
Technically, the Core X V2 will work with Thunderbolt 4 machines. But to unlock the full bandwidth necessary for today’s most powerful GPUs, you’ll need a TB5-capable machine. For now, the Core X V2 seems to be a niche solution waiting on a broader ecosystem rollout, with a price tag and feature set that may leave cost-conscious users scratching their heads.
