PowerColor Devil Box Review

PowerColor Devil Box is a bare-bones Thunderbolt 3 external GPU enclosure with a 500 W power supply, full-length graphics card support, AMD XConnect certification and an active fan.

The Devil Box is a Thunderbolt 3 eGPU enclosure that houses a desktop graphics card and a 500 W power supply. It is certified for AMD XConnect. The chassis is vented steel with an active fan, and it takes full-length cards. It is bare-bones: there are no extra ports beyond the PCIe slot. Launched around $299.99 in 2017, it is a bare-bones Thunderbolt 3 design, so it is a weak pick if you want hub-style extras.

Overview

The Devil Box is a straightforward, no-frills full-size PCIe enclosure with an internal PSU, styled after PowerColor's Red Devil graphics card line, and was among the first wave of Thunderbolt 3 eGPU boxes announced in 2016-2017.

Comparison to Alternatives

Compared to the already-catalogued PowerColor Gaming Station, the Devil Box is the earlier, plainer model with no Ethernet or USB hub. It competed directly with the original Razer Core and Mantiz Venus at launch, all racing to be first to market with Thunderbolt 3 eGPU support.
