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.

929 Can I use a Sonnet eGPU with Boot Camp?Jun-21-21
930 What kind of performance can I expect from the NVIDIA Titan Xp (Pascal) with the eGFX Breakaway Box?Nov-06-17
In a Sonnet eGFX Breakaway Box, the Titan Xp was performing at:
Single-precision Float 12.4 Tflops/s
Double-precision Float 416 Gflop/s

Note: You may have read that some other manufacturers' external graphics boxes--even some with a higher power supply rating--fail under heavy load with the NVIDIA Titan Xp (Pascal) card. Not so with a Sonnet Breakaway Box. In choosing a power supply, Sonnet carefully considers not only the eGFX Box nominal power rating, but also its instantaneous peak power delivery capability. Sonnet runs many rigorous tests (including the CUDA-Z benchmark, set to Heavy Load Test Mode). The Sonnet eGFX Breakaway Box must pass the most stringent tests before we put it in your hands.

999 How do I get external graphics working on a Gigabyte motherboard?Feb-15-18
Steps to get an eGPU working with a Gigabyte motherboard:

1. Install latest BIOS (e.g. use Gigabyte Q-Flash utility within the BIOS to update via USB-drive)

2. Install latest Thunderbolt firmware (available on Gigabyte.us support site)

3. Uninstall the existing Thunderbolt bus driver, and then install the latest Thunderbolt bus driver.
(We got bus driver version 16.3.61.275 working,. This is the latest one as of February 2018)

4. Change settings in the system BIOS to allocate enough PCI resources to the Thunderbolt bus.
....Boot into BIOS by pressing Delete key during boot
....Go to "Peripherals" > "Thunderbolt (TM) Configuration" > "ThunderBolt Detachable Graphics Support" > switch to "Enable"
....Increase the following settings to its maximum values:
........"Reserved Memory for Dgpu" > enter maximum allowed value, typically 299
........"Reserved PMemory for Dgpu" > enter maximum allowed value, typically 499
........"Reserved Memory" > enter maximum allowed value, typically 4096
........"Reserved Memory" > enter maximum allowed value, typically 4096
....Save settings and exit BIOS

1110 I'm trying to use four HDMI monitors by adding DP-to-HDMI adapters, but it doesn't work.Jun-21-21
Use at least one active DP-to-HDMI adapter.

Display Port signal is not compatible with HDMI.

However, on most modern GPU cards, the DisplayPort output is a Dual mode DisplayPort (DP++), which has the ability to recognize and adjust the signal to HDMI when a passive DP-to-HDMI adapter cable is connected, but only up to a point. If the HDMI monitors you are trying to connect are identical (use identical video signal timings), then you should be able to use passive adapters for all. However, if the monitors are different, then there may be a limit of two special clocks to drive passive DP to HDMI adapters; ergo only two HDMI monitors may be supported with passive adapters; the third and subsequent monitor would need to be native DisplayPort or would need to use an active DP-to-HDMI adapter.

Older generation GPU cards require the use of active DP-to-HDMI adapters on every DP port.
