The majority of Thunderbolt 3-enabled external chassis for video cards are rather big in order to accommodate high-end graphics adapters that tend to feature large PCBs and cooling systems. Meanwhile, not everyone needs a 300 W GPU and has enough space for a large box on their desk, but finding a compact and suitable eGFX enclosure may be problematic as the choice is very limited. Fortunately, PowerColor and VisionTek have just released three of such products.

While we are talking about three different SKUs, PowerColor’s Thunderbolt 3 eGFX Box 180F and Thunderbolt 3 eGFX Box 240F as well as VisionTek’s Thunderbolt 3 Mini eGFX (240 W) enclosures actually rely on the same TBX-180/240FU chassis developed by PowerColor and originally showcased at Computex in June, 2018. There are important differences though: PowerColor sells its boxes outfitted with its Radeon RX 560 and Radeon RX 570 graphics adapters, whereas VisionTek offers just an enclosure.

Measuring 215×153×68 mm, the said eGFX chassis can accommodate double-wide video cards that feature a 175 mm length and a 131 mm height, which generally limits compatibility to mainstream and Mini-ITX graphics adapters that have appropriate power ratings.
