Hi,
i want to buy a sonnet breakaway box but i'm not sure what psu i should buy and what version of the sonnet egpu case.
i want to use a AMD Radeon Vega Frontier Edition Liquid with this case. For a Mac Pro 2013 and a Mac Book pro 2016.
Sonnet says on there Webpage Enermax Revolution SFX 650W SFX12V would be good. i was thinking maybe a SFX-L PSU fits too with more power and a quieter fan like the Silverstone SX800-LTI. Have anyone tried a SFX-L PSU?

Correct me if im wrong, doesn't the box come with a 300 / 550w PSU? Seems like that if I read the key features of the different offerings.

Yes there is a version with 550w but Sonnet says its not enough and i think also very loud.

at Sonnet FAQ i found this:

AMD Radeon Vega 64 (liquid cooled):
This card requires a 650W power supply and a Power Delivery limit of 15W. Sonnet has Thunderbolt certified the eGFX Breakaway Box models including their power supplies, and we cannot officially recommend changing the power supply. if you must have Vega 64 (liquid cooled) support now, you can replace the stock power supply in the Breakaway Box 350 which is programmed for 15W PD (but not the Breakaway Box 550, which is programmed for 87W PD, and not the Breakaway Box 350 Developer Edition which is programmed for 60W PD) with an Enermax ERV650SWT Revolution SFX 650W Plus Gold. If you upgrade to this power supply, Sonnet will honor the warranty for all other covered components.

Hi, I have liquid cooled Vega (SAPPHIRE Radeon RX Vega 64 Liquid Cooled) in Sonnet Breakaway Box 550 with replaced SFX-L PSU and it's working. PSU is SilverStone SST-SX800-LTI. Yes, there is not much space for cables between PSU and water cooling block.

@hana_dusikova would you mind sharing some photos of the internal arrangement? I'm looking to do this swap for Mantiz Venus so that it can power the Vega Frontier Air.

I checked the spec of the power supply, seems to be a very good power supply:  http://silverstonetek.com/product.php?pid=731 -

Combined +12V
792W

In less than 2 weeks AMD will post Radeon Adrenalin 18.1.1 driver which has a number of stability improvements for XConnect as well as other fixes, I would suggest you to try that driver.

I tried the exact same setup. I couldn’t get it stable. Under the load, the gpu shuts down with SX800 installed in OS X.

Both the Geekbench 4 and Heaven could not complete. The Valley did, but the shut dwown also happened under normal usage.

The VA reading at the wall never went over 350, so it can’t be overload.

I just returned my SX800 and went back to stock.

The same happend to me too yesterday with Geekbench 4 and Heaven. The first time i tried Heaven it complete. 

Damn so maybe i have to return my SX800 too. I think i will try the Enermax Revolution SFX 650W  then.

How was the Fan noise?  The Fan was very load on my setup so much loader than my Mac Pro.
