The Mantiz Saturn Pro II is a Thunderbolt 3 eGPU enclosure that pairs 550W GPU headroom with 100W of host charging over a single upstream TB3 cable. A secondary TB3 controller drives its integrated dock — five USB-A 3.2 Gen 1 ports, Gigabit Ethernet, and an SD card reader — so one cable carries graphics and peripherals. The internal 750W Gold PSU is standard for that era's eGPU class. Host machines need a TB3-capable port with external GPU support; USB4-only Windows laptops may work but official compatibility is Intel-TB3 certified.
Thunderbolt 3 eGPU enclosure with 550W GPU power, 100W host charging, built-in USB hub, Gigabit Ethernet, and SD card reader.

Notes & Compatibility
Dual Thunderbolt 3 controller design — primary controller drives the GPU, secondary controller drives the integrated dock. Internal 750W Gold PSU feeds GPU (up to 550W via 3x 12V 8+2 PCIe power connectors) and host (100W PD). Rear power inlet type unconfirmed from public specs — typical for 750W internal PSUs is IEC C14, but omitted here pending manual confirmation. 2.5″ SATA III bay is internal, not an external port.
