907 Can I upgrade the power supply in the Sonnet eGFx Breakaway Box or Breakaway Box 550?Sep-20-19
Sonnet has Thunderbolt certified the eGFX Breakaway box including its power supply, and we cannot recommend changing the power supply.

Sonnet uses the FSP FSP550-50SGGBA in the Breakaway Box 550.

Sonnet uses the Enermax ERV650SWT SFX 80 Plus Gold in the original Breakaway Box 650. (The newest Breakaway Box 650OC uses an ATX power supply.) Sonnet uses the higher-performance Akasa AK-FN059 fan in Breakaway Box 650.

If you upgrade the power supply and fan, you will have more power available to a graphics card, but you will not alter the upstream power delivery, which is programmed into the unit. Note that upstream power continues to be provided even when the computer is sleeping.

970 How do I use the Breakaway Box or RX 560/570 Puck with the LG Ultrafine 5K Display sold on the Apple store?Jan-06-21
The LG Ultrafine 5K Display connects via Thunderbolt 3. To give both the display and the Breakaway Box/Puck each maximum bandwidth, connect them to independent Thunderbolt 3 controllers, if possible.

The 13" Macbook Pro with Touchbar, 15" MacBook Pro, Mac mini and iMac Pro have two independent Thunderbolt controllers. Connect the Display and the Breakaway Box/Puck to ports on different sides.

The 13" MacBook Pro without Touchbar and the iMac with Retina display and the have only one Thunderbolt controller. The LG Ultrafine Display will reserve all the bandwidth it needs, and the Breakaway Box/Puck will be allocated the remaining bandwidth, which may affect performance of the Breakaway Box/Puck.

If you are using macOS 10.14.6+, you can accelerate applications and games with the eGPU if they support GPU acceleration...
• Select the app in Finder
• Get Info
• Select Prefer External GPU

Do not select Prefer External GPU for Adobe Premiere or Apple Final Cut Pro. These applications automatically manage eGPU usage.

Professional applications that use an external GPU generally may have a preference selection inside the app to select the external GPU.

1084 I connected my monitor to the Breakaway Box, Breakaway Puck, or DuoModo eGPU Module on my 2018 or newer Mac mini, but it boots with a black screen.Jun-21-21
If you have a 2018 or newer Mac mini with FileVault turned on, you must connect your primary display directly to the HDMI port on your Mac mini during startup in order to enter your encryption password. After you log in and see the macOS Desktop, you can unplug the display from Mac mini and connect it to your eGPU.

Under macOS 10.14.6, a 2018 Mac mini with some GPU cards must be booted with a monitor connected to the Mac mini's HDMI port. If you have a Mac mini with an affected GPU card, you must either:
(a) Update to macOS 10.15.7+

(b) Connect an HDMI display emulator plug to the Mac mini HDMI port and mirror displays. (You must make sure that the HDMI display emulator is the Master Mirror. Drag the menu bar to the HDMI display emulator window before mirroring.)

(c) Connect a monitor to the Mac mini's HDMI port to log in, and then move the HDMI monitor connection to the eGPU.
