## Questions & Answers

**Q: Does this work with the razer blade if I use a 1050ti?**
A: This product is not designed to work with graphic cards because it does not have adequate power.  Our product for graphic cards is our eGFX Breakaway Box

**Q: How much power (in wattage) is being sent to the pci-e lane?**
A: The SEL and SE I both send the PCIe specification to the x4 PCIe 2.0 slot: 25 Watts.

**Q: Is a Thunderbolt 3 (USB-C) cable included?**
A: Yes, all of Sonnet's Thunderbolt 3 and Thunderbolt 4 products include a Thunderbolt cable.

**Q: Would this work if i used a thunderbolt 3 to 2 adapter (i have a macbook pro 2013)and stuck a graphics card in it**
A: This would not be a very good product to use a graphics card with and especially if you are going to adapt it to thunderbolt 2. I do not believe that this is a fast enough port for modern day graphics cards.
