Ģ) Remove case from Thunder2 enclosure and install graphics card. I have personally never used it and have been using iStat Menus for years.

NOTE: If you prefer a free alternative to iStat Menus then you can use HWSensors. Prudent Way 90W AC Power Adapter (AC90LE) Just make sure your AC adapter is 90 watts or more and can be set to 12 volts. This gives 75 watts for graphics card with the remaining left over for the Thunder2 board and Thunderbolt cable. Using a normal ac adapter the Thunder2 automatically turns on at boot and turns off at shutdown. Using a normal AC adapter the Thunder2 automatically turns on at boot and turns off at shutdown. I must reiterate that I have been using this setup for nearly 10 months on a daily basis. I saw one of the engineers working at AKiTiO confirm that the Thunder2 does in fact deliver 75 watts over PCIe while discussing the differences they implemented for the OWC Helios on some forum somewhere ( ). People might go ape bananas over this saying that the PCIe slot in the Thunder2 only allows 25 watts through but they are wrong. If your card is not the same as mine (EVGA GTX 1050ti SC 4GB) then make sure that its maximum power draw does not exceed 75 watts.

The graphics card I use receives all its power from PCIe slot and does not require a six or eight pin connector. I use a regular universal AC adapter which came with an assortment of connectors and has a voltage switch for 12 volts. NOTE: I do not use a molex connector or external power supply. I have never attempted to get the internal screen working. This setup has been in constant daily use with macOS Sierra since April 2016 (nearly 6 months at time of posting).
