Any sub $199 models and/or models without included PSUs?
The majority of the cost must be the power supply inclusion with eGPUs so I'm curious if anyone knows of either any units that do not include a PSU or that are closer in the $200 (or less) price range? Also, while I'm here, how do you daisy chain from one eGPU box to another if you only have 2 TB3 ports?
This is a naked module without a PSU but also without a case and any other additional ports. As you can see, the majority of the cost is the thunderbolt 3 standard itself. R43SG (~$30) without TB3 is ~$100 cheaper than R43SG-TB3 and the only difference is NVMe to TB3 adaptor. Anything to TB3 is $$.
Anyway, there is no PSU included, so with a little tinkering you can use it with any PSU. The disadvantage may be only 15W power delivery to your laptop, so you probably can't power your machine only with it (skipping the standard PSU).
