It seems kind of silly to me to ghetto-rig an Akitio Node Lite for a half length AMD PCIe card that uses 100 watts-200 watts; I.e. might as well get a full size eGPU if that’s the case.  But is there any AMD card that uses under 75 watts for an “easy” mini eGPU setup (One where you just plug in a new power adapter)?

Aside of professional cards, the RX560 (and the slightly less powerful RX460, if you can find one) is as high as you get. Look for a model that takes no additional power connector, such as this.

If you're wiling to pay for it, the Radeon Pro WX 5100 also fits the bill, but these are expensive. Of course, with the current card prices, where a RX570 can cost 300$, it actually isn't entirely horrible, price-wise.

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

Thank you 🙏 But will those cards be compatible with High Sierra?  From what I understand only the RX 470, RX 480, RX 570, RX 580, and Vega will be compatible with High Sierra (at least with Beta 7) without any hacks; but of course I could be wrong and can certainly change in the future.

Thank you 👍  I never took that into consideration about looking for a graphics card that has no additional power connectors on it -- great advice.  But will the RX 460, 560, and WX 5100 be compatible with High Sierra out of the box?  I was under the impression High Sierra will (so far) be "for sure" compatible with RX 470, RX 480, RX 570, RX 580, and Vega; but no other cards -- yet.  But wait, the RX 570 consumes less than 75 watts?  Are you talking about the RX 570 ITX? (But looks like there's a 6 pin power connector on that)

I'd rather not state any opinion regarding High Sierra and the eGPUs it will support so as not to cloud your judgement (anything can happen). Currently, only the RX 580 is officially supported. Unsupported configurations include the Vega series. There might already be some post regarding the 560 and lower cards being supported or not on High Sierra which you might want to try finding (I vaguely remember some post).

I also sort of side-stepped the list of what is actually going to be supported: It is hard to tell, aside of the ones they already do support in the beta and/or have stated so. I have faith in our intrepid kexters and scripters that anything is possible, but YMMV. My list of cards is what works on slot-power alone.

Note: The RX570 does NOT run on slot power alone. They all need an extra power connector (or two, for the higher-end models).

Correct, while the RX 580 is the only one officially supported, what I meant is that the 470/480/570/580/Vega will work out of the box without any additional hacks. Because it's reasonable to assume that the Vega will be supported (at least by December) since that's what the iMac Pro will use for instance.  But it looks like the 560 doesn't work on High Sierra.

Thank you yeah I didn't think the RX 570 ran off PCIe bus power by itself.  So as of right now looks like us mac users are out of luck in the mini-eGPU scene without heavily modifying our PCIe boxes and/or modifying the operating system.  (I generally avoid hacking macOS since it can negatively affect the stability of apps I compile)

I believe Apple said official eGPU support in Spring 2018.  I'm assuming at that point we'll be able to use any current mainstream Nvidia or AMD GPU in an external enclosure without issue.

Apple & Nvidia really can't put aside their issues and get some proper drivers baked into macOS?  It's hurting both sets of customers.  

Rant over.  @machsoftwaredesign, what's the primary app you're trying to accelerate?  GTX 1050 & 1050Ti can clock in around 75W as well, and may be worth consideration.

Correct, I assume Apple will put out a list of (AMD) graphics cards that are eGPU compatible with High Sierra by Spring 2018 -- looks like it may be completely up to Nvidia if they decide to finish developing their Mac beta drivers or not but we'll see.  I agree though, not like it would be hard for Nvidia And Apple to partner up and release some Mac drivers; they both certainly have the resources to pull it off since there certainly seems to be demand for it.

And oh boy I use a ton of apps so it'd be hard to pinpoint one that I'd like to see accelerated; but that would probably be XCode.  Followed by Cinema4D, Unity, Photoshop (but may switch to Pixelmator soon), Final Cut Pro, Motion, Starcraft 2, and CrossOver (WINE) for Path of Exile.  I assume Cinema4D, Unity, and CrossOver all use OpenGL but could be wrong.

But at this point I think I'm just going to go with the RX 580 or RX Vega since they'll support VR development, but was simply considering a mini eGPU for a secondary Mac and was curious whether it was possible with AMD cards without heavy modification.  Thank you for the response though 👍
