Hi All,

 

I have the Apple Dev Kit versions of the Sonnet Breakaway Box.  I have since upgraded to a 2017 15in MBP and the upstream power is not enough to charge the 15in MBP.  I know at least one person here has upgraded their PSU, but I am wondering if anyone else has?  If so, could you please share your suggestions on what PSU you chose.  Obviously my main goal would be to have one with enough upstream power to charge my 15in as well as to possible upgrade the video card at a future date.  Also, it would be great if its fan was also quiet like the one that comes stock in the Breakaway Box.

 

Thanks

Is it a standard ATX power supply? Or a small form factor?

It uses SFX power supply. The firmware of the enclosure dictates the power delivery rating. I don't think it'll change when you swap the PSU. The Sonnet Breakaway Box as part of the Apple Dev Kit gets 60W power delivery using a 350W PSU. The retail version uses the same components but only has a 15W power delivery.

But the 550 version delivers 87W upstream power.  So is it your belief that the 550w unit has different firmware?  And if so, if on the same hardware can one just update the firmware?

 

I know someone on these forums upgraded their PSU, we discussed it in another thread.  I wonder if he can measure the power upstream.

I believe it's the firmware that decides how much power delivery is sent over the TB3 cable. My retail version Sonnet Breakaway Box has version 25.2 with 15W. The one with Apple Dev Kit has version 25.1 with 60W. A firmware update would definitely change this PD number.

Mantiz Venus has the same TB3 board and the early firmware had 60W. We provided Mantiz team with feedback about the needs for 87W power delivery to accommodate the 15" MacBook Pro. They baked a new firmware and Intel approved it.

I'm deciding between buying the Akitio Node vs Sonnet breakway 350. I dont care about charging or not the macbook, but I care a lot about high performance. I have a evga 1080 ti ftw3, and I know I'll probably have to replace the eGPU enclosure PSU. So it is possible to upgrade the Sonnet PSU right? Between the two, considering the PSU upgrade, which one would you pick guys?

@Rycco, the following features of the Sonnet Breakaway Box 350 are why I'd be buying it instead of the Node:

  • Breakaway Box's quieter fan
  • noticably lighter and easier-to-access chassis
  • Using a common DSL6540C V1.0 circuitboard (also in Mantiz Venus,  Powercolor DevilBox, Apple's Sonnet Breakaway 350 with 60W PD). Useful if needing to source these or will have more value as a parts enclosure in the secondhand market.
  • Apple using the Sonnet Breakaway 350 in the dev kit ensuring it's passed Apple's quality checks
  • Sonnet having better international representation (important for Brazilians or when offloading the unit)
  • Sonnet has a good quality 350W Akasa AK-PS035AF01  SFX PSU, shown here and probably similar to this

 

The single spec advantage of the 400W PSU in the Node may  itself be of questionable quality or has a lower real wattage given:

Nando4 thanks so much for your inputs. Yeah I'll stick with Sonnet and upgrade its PSU as soon as I get it. Last question, replacing its PSU won't require any other tool/special cable right?

Nope, use a SFX PSU, swap the screws, and you are good to go. Just keep in mind if you haven't already that it would likely make more sense to go with a modular unit as only the 24-pin and PCIe power connectors are needed.

I replaced the PSU in my Sonnet Breakaway box (from Apple Dev Kit) with a SilverStone SX600-G without any issues. You may want to look into Corsair as well.

Hope this helps!

Do you know what your upstream power is now that you upgraded?  I'm wondering if it will charge a 15 in MBP
