Sonnet GPU-550W-TB3 Overview

  • 1Description

Upgrade your Thunderbolt 3-equipped notebook's graphical capabilities with the eGFX Breakaway Box from Sonnet. The eGFX Breakaway connects to notebooks and ultra-compact desktops via a Thunderbolt 3 connection to provide one PCIe 3.0 x16 slot, so you can install a user-supplied dedicated graphics card for gaming or creating 3D visuals. For broadcasting environments, the slot can accept a video capture card. To support a wide variety of cards, Sonnet has designed the eGFX Breakaway with ample space to house one PCIe card that features a full-length, full-height, and double-width form factor.

Powering the dedicated graphics card and even your notebook can be accomplished with the built-in 550W power supply, which delivers up to 87W of upstream power for recharging your notebook's battery. The power supply sports two 8-pin PCIe power connectors to support PCIe cards requiring up to 375W of power. Aside from power, the eGFX Breakaway comes outfitted with a variable-speed fan that cools all the internal components while staying quiet. Included along with the eGFX Breakaway is a 1.5' (0.5m) Thunderbolt 3 cable to help you connect with your computer.

    Sonnet GPU-550W-TB3 Reviews

    eGFX Breakaway Box with 550W Power Supply is rated 4.3 out of 5 by 8.
    Rated 5 out of 5 by from Awesome addition to my iMac Pro! I purchased this so I could add an nvidia gpu to my iMac Pro. Apple currently doesn’t officially support Nvidia EGFX cards but there is a script on github that got it working nicely with OSX. I do not use any monitors connected to the GPU so that the full processing power and ram is available for rendering work. I would certainly suggest this to anyone wanting more graphics power for 3D rendering and rastering. I have a 1080 GTX in it right now with a 1080 TI on the way.

    Rated 4 out of 5 by from Works As Expected The case is well made, and installation was easy. I purchased this so I could hook up a Vega 56 to my MacBook Pro. No issues and the card was a breeze to install. The only reason I took one star off was the silly decision to provide it with such a short TB3 cable. What were they thinking? The only way I could hook up my laptop was to turn the box around. Unfortunately, the heat vented towards me, and my laptop. It felt like a space heater when I tried rendering a 3D Model I was working on. This is not something I need when it's well over 90 outside. So I had to spend another $50 to get a cable that was a little longer. I am really dumbfounded by the choice of cable supplied. Charge me $50 more so I could use it properly and not waist my time buying something it should have come with. However, I still recommend this box, but you may want to consider purchasing a longer cable.

    Rated 5 out of 5 by from Expect top quality from Sonnet Transforms my 3 lb. ThinkPad X1 ultrabook into a graphics workstation powerhouse! Tested with GeForce 10, Quadro P4000 and Vega cards. GPU benchmark performance is very close to real workstations with x16 bus despite x4 lane PCI limitation of TB3 connection. Faster cards yielded faster benchmarks indicating to me that x4 lane bottleneck shaves about 10-20% performance but doesn't plateau with faster GPU's; at least not for 1080 or Vega. Power supply is industrial equipment quality and cooling is quiet and effective. 550W version includes two 8-pin power connectors.

    Rated 5 out of 5 by from Perfect Complement to MBP 13 I was torn between getting an MacBook Pro 13 or a 15. I love the portability of the 13 but knew I'd miss the power of a discrete GPU. eGPUs to the rescue! It was a long wait until this bad boy's release date, but it was well worth it. I paired this with a Radeon 580 Gaming GPU and a 27 Apple Cinema Display. Now I have both portability and power when I need it. Having to restart MacOS High Sierra when I plug it in is a minor inconvenience, but that's my only gripe -- and not the fault of this eGPU.

    Rated 4 out of 5 by from Almost a "5". I really like it This device meets most of my basic expectations now...perhaps with additional time to mature with the macOS system, it will be a "5" ?star product. ?Right now it is a "4.5" I use it with a 13" MacBook Pro 2017 model. ?It is basically plug & ?play but I had to fiddle with the MBP to understand how to make it work well with the big external screen. ?There are no settings or anything to do with the Breakaway except put in the video card and plug it in. ?Currently I'm using a RX480 in the Breakaway 550. ?Without the Breakaway, none of my Steam games are playable. ?With it, almost everything is...I noticed a couple of minor stutters and render ?anomalies with those that are more demanding. I love that it works perfectly with the lid closed on the MBP. ?Bluetooth keyboard and universal wireless trackball continue to work as expected. ? What I don't like: ?(1) No control over the video card, i.e., no utility to overclock the RX480. ?The Breakaway 550 has more than enough power and cooling capacity to OC this card but ATI does not provide any software for macOS. ?Apple apparently provides the drivers with macOS 10.13.04 - thank goodness. But the RX480 will OC like a banshee when plugged into my Window's desktop using the AMD software for Windows. ?What a let down - a little OC would go a long way at improving the enjoyment of this product. (2) The TB3 cable provided by Sonnet is too short. ?You better have room on your desk next to your computer because it ?is only about 18" long. ?Can't believe they couldn't even throw in a full meter. ?The big expense is in the connector ends - not the wire. ?(3) I wish the Breakaway would go into a complete sleep mode when the controlling computer is shut down. ?Right now the power supply fan continues to run when the computer is shut down. (Perhaps the power supply might get warm if plugged into a 15" MBP with a dead 13" didn't). General comments: ?Product is well made. ?Sturdy. ?Not pretty but far from ugly. ?I build lots of computers and it reminds me of an inexpensive computer enclosure. ?A few sharp edges inside but that is nothing unexpected in all but the best enclosures. ?Power supply is good and the mother board containing the Intel TB3 chip and support circuitry is good. ? Set-up instructions are good. ?Very quite when operating (the RX480 is just limping along). ?Provides full 87W of power to the MBP (even though the 13" MBP only requires 60W). ?Works at full 40Gbps TB3 speed. ?The Breakaway and the Satechi TB3 port adapter make a MBP as powerful and useful as most desktop PC machines. ?An extremely well-behaved system!

    Rated 1 out of 5 by from Bad card for a power supply This product arrived without original box and without AC and Thunderbolt 3 cables. Sonnet is apparently a good product. B & H recommended me to use this case with an "EVGA GeForce GTX 1080 Ti SC GAMING Black Edition Graphics Card", but it is not compatible as eGPU. I am using this case as a power source only for my MacbookPro.

    Rated 5 out of 5 by from Nice addition to a MacBook Pro 13" for photography The breakaway box is well constructed. It's solid and has a great finish. The top removes and reinstalls fairly easily (follow the included directions as it doesn't just slide off). I've installed a Radeon RX580 in the breakaway box. The installation was easy with the included power leads.? The box ventilates well with the mesh on opposite sides and the built in fan (in addition to the fans on the RX580). The included fan is pretty quiet as I barely notice it in a quiet work environment.? I have a 27" BenQ monitor and a 24" Eizo monitor connected to the RX580. I connect the breakaway box to a MBP 13" using Thunderbolt 3 and see a noticeable improvement in photography applications that utilize the GPU. The external system works well with High Sierra 10.13.4. I did buy a longer thunderbolt 3 cable so the breakaway box can sit on the floor out of the way. The included cable is very short. With two monitors and the laptop sitting underneath one of the monitors, it would have been very difficult to get the breakaway box positioned on my desk as well with the included cable. I'm sure the box's fan also seems quieter because it's sitting under my desk rather than on top of it.

    Rated 5 out of 5 by from eGPU Power for Mac Quality of breakaway box is great, looks nice too. Works as it should, very happy with purchase.
