Razer Core X Review

Razer Core X eGPU enclosure Thunderbolt 3 650W PSU triple-slot no RGB Windows Mac

The plain-black sibling to the Chroma, Razer's original Core X strips out the RGB lighting and cuts the price while keeping the same vented aluminum shell and a 650W internal supply strong enough for nearly any single desktop card of the era. It became a favorite budget pick precisely because it does nothing flashy: plug in over Thunderbolt 3, drop in a card up to triple-slot width, and go.

Overview

Released in 2019 as a lower-cost alternative to the RGB-equipped Core X Chroma, the Core X uses the same vented steel-and-aluminum chassis and 650W internal PSU but omits Razer's Chroma lighting and per-key-style effects. It accepts full-length, triple-slot-wide graphics cards, charges a connected laptop at up to 100W over the same Thunderbolt 3 cable, and adds four USB 3.0 ports plus Gigabit Ethernet for use as a desktop dock.

Comparison to Alternatives

Against its own sibling, the Razer Core X Chroma, the Core X is functionally identical minus the lighting, so it's the better pick for anyone who doesn't want to pay for RGB. Compared to the newer Razer Core X V2 (Thunderbolt 5, 850W), the original Core X is limited to Thunderbolt 3 speeds and lower PSU headroom, but it remains far cheaper on the secondary market. Versus the Sonnet eGPU Breakaway Box 750ex, the Core X has a larger internal PSU but fewer certified compatibility guarantees for Mac users, where Sonnet's official Apple certification carries more weight.
