Sonnet Breakaway Box Review - It's cool to be quiet
Unfortunately Intel would only certify eGPU enclosure with TB3 board, PSU, and cooling fan/s. Thunderbolt 3 PCIe enclosures are what you want if you'd prefer to build one yourself.
Have had the same setup which was working great, sadly the logic board on the 350DE seemed to have gone south just about 3 weeks after the manufacturer's 1 year warranty expired.
Proceeded to contact Sonnet CS for guidance, after double checking my troubleshooting steps it became obvious that it was the logic board that was faulty. I inquired about purchasing just the logic board that contains the PCIE/TB components. Was forwarded to the RMA department after proving the serial number for the 350DE. The RMA department informed me that the logic board is not sold separately and that I would be better off purchasing a new 350 from amazon or from Sonnet directly. Given that the 350DE provides power over TB3 a regular 350 would not be an option so I ordered a Sonnet Breakaway Box 550.
After thinking things through I decided to return the Sonnet Breakaway Box 550 and I am considering the almost identical product from OWC. The OWC Mercury Helieos FX offers a 3 year warranty. Have used other OWC products previously so thinking about trying the OWC Mercury Heliios FX. Still own another Sonnet Breakaway Box 550 that so far has been working but the 1 year warranty is a concern, and the lack of availability of the logic board as a component that can be replaced.
Does board have aditional pins for RGB Fan? I would like to buy Breakaway and replace Fan with AKASA Vegas R7 RGB LED for example, but I would like to know if board even has pins for it.
