Now, there's one caveat to using an eGPU, and it's not specific to Razer or any other brand. If you're using disk encryption (APFS, Encrypted) on a Mac Mini, you will need to swap to the default HDMI port on the Mac Mini when booting and/or rebooting, and then back to the eGPU once the system is online.
1). If you have a monitor with an extra DisplayPort or HDMI port, connect your primary to the graphics card within the eGPU and the secondary to the HDMI port on the back of the Mac Mini. When you boot, swap to the HDMI port on the Mac Mini using the display settings. Once the Mac Mini is booted, swap back to the port on the graphics card.
2). Backup your data, and reinstall MacOS (making sure you format the disk before reinstalling) and select APFS (not APFS Encrypted). The issue only impacts boot when disk encryption is used and by removing that from the boot sequence, the eGPU will be used by default.
If you don't absolutely *need* encryption enabled, I would go with #2 to minimize the hassle.
# Radeon VII Notes
For those wanting to use a Radeon VII, this eGPU enclosure *does* work, very well, though as of this review, you will need to make sure you are using the *beta* of MacOS (currently 10.14.5 Beta). The Radeon VII does not currently work with the default (non-beta) version of 10.14 as Apple doesn't include the drivers for the card in versions prior. Much like the issue with disk encryption, you will see a black screen if you're not using the beta release.
The larger question here is, at nearly $300 (at the time of this review), is the Razer Core X worth it? What about when paired with a $400-$700 card? I'd say absolutely. If you have a MacBook Pro or Mac Mini with Thunderbolt 3 and you need something that you can quickly and easily upgrade with a new card in the future, this is an amazing enclosure.
I originally bought mine for a Vega 64, though recently swapped in a Radeon VII. I've bought a second one for the Vega 64 so it still gets used on the same Mac Mini (as the Mac Mini will support 2x eGPU's -- for best results, I'm adding them to the first and third TB3 ports).
Razer practically begs you in all of its documentation to contact Razer support instead of returning the product if you have problems. Ignore them and just return it. If you contact Razer, they will spend time "troubleshooting" your problem just long enough for Amazon's return window to close, then find a way to drop you and say it isn't their fault. In my case, Razer "support" ran through the usual troubleshooting steps: Power cycle. Install updates. Reinstall the ethernet driver. Reinstall the thunderbolt driver. Plug the ethernet into a different port on the router. Plug the ethernet directly into the modem. Etc. Finally, just as Amazon's return window closed, they hit me with what I thought was just another troubleshooting step: Try to borrow a different laptop to try it with. Seemed like an innocent troubleshooting step to me: we're just trying to isolate the problem to software or configuration and rule out a hardware problem, right? Nope. As soon as I informed them that the ethernet works well with a borrowed laptop, they dropped me saying the Core X Chroma is working "as advertised", it is not their problem, and I should contact the manufacturer of my laptop. Seriously. Razer is a system manufacturer, so they know as well as anybody that no system manufacturer EVER provides support for third-party peripherals. It is clear all Razer "support" was doing was stringing me along until Amazon's return window closed. So now I'm stuck with a device whose major "feature" setting it off from its cheaper competition doesn't work.
Learn from my experience: Just return it. Never, ever contact Razer "support."
I’ve put a PowerColor Radeon Vega 64 in my Razer Core X to hook up to a dual-booted OS X/Win10 Mac mini 2018. Once you actually get the thing running, it’s absolutely seamless and a delight. My issues are more along the build quality.
The Razer Core X uses a magnetic sensor to verify that the case is closed before it permits the PSU to start up. If your rails are wonky, or the sensor doesn’t make the best contact at the end of the rail, you’ll think yours is DOA. After lots of swearing and attempting to bend the back rail into just the right position, I finally figured out that taping a cheap vinyl refrigerator magnet over the sensor on the end did the trick.
Additionally, the board components are a little fragile. I replaced the stock 120mm fan with a bequiet! Silent Wings 3 (w/o PWM), and the plastic retainer clip on the fan plug broke off. Still works, but fragile. Next time I open up the case I’ll probably secure it with some kapton tape.
Outside of the two issues above, it’s been a champ in both Windows and OS X. I’m quite happy overall.

So... Is it cheaper to add a eGPU or just get a 15" MacBook pro i9-9880HK 16GB RAM 512GB storage with Radeon Pro Vega 20 for $4159 ? GST other applicable taxes not included yet!!!
Better yet. Get a Dell Alienware Area 51M laptop with 17.3" 144Hz G-sync ,i9-9900K, 32GB RAM, 1TB M.2 storage with Nvidia RTX2080 for $4389.
I am having great success with this Razer Core X external GPU enclosure attached to an Asus Zenbook Deluxe 8th-gen i7 ultrabook. I am NOT gaming, I'm primarily running the Adobe Creative Cloud usual suspects: Photoshop, Premiere, Illustrator, Dreamweaver as well as Autocad and Revit. I installed a NVidia Quadro P620 card in the enclosure. Everything is far faster than before - very pleased with the upgraded performance. Installation in Windows was painless for the most part, but you should be aware that there was a very long delay while Windows detected the enclosure and set up the software for it, and there is absolutely no indication that anything is happening. If I didn't have patience I may have rebooted too early and screwed the whole thing up, but I checked Task Manager and could see the process taking about 20-30% cpu so I just let it go until it calmed down. Still no indication that it finished when it finished, I just waited a few minutes more then rebooted. Then I downloaded the latest card drivers from NVidia (ODE version not QNF) and installed them. Rebooted again. Then I plugged in the actual Display Port cables from four Asus 2560 × 1440 monitors and everything came up roses. The enclosure is practically silent - virtually impossible to tell it's even getting power. And huge. In fact it's bigger than most of the desktop computers in our offices. But that doesn't matter because it just sits behind the screens and does its job quietly out of sight.
I docked one star because I could not believe that I had to pull out the cordless drill and drill a hole to be able to secure the Quadro card in its slot. This won't be an issue for those with dual-width or wider video cards, but the Quadro P620 is a single-slot card and there's no hole to fasten the card's bracket to the enclosure case. Easy fix by drilling and tapping a hole in the case, but now I have to find a slot adapter cover plate to fill in the gaping hole beside my Quadro card, since the adapter cover that comes with the enclosure cannot be used as it's designed to be discarded once a card is installed. It's too wide to use. Kinda lame. If it weren't for this deficiency in design I would award this enclosure with 5 solid stars. I hope this helps.
UPDATE MARCH 2/2019 This enclosure is still working perfectly. I use it every work day. Great product.
All in all, great looking device but terrible execution. I didn't expect this at all from Razer; I purchased this eGPU because I didn't want to do research as I thought the Razer Core X Chroma was the best of the best. I'll purchase a different eGPU (Sonnet eGFX) and will update this review to see if it works on my laptop better than the Core X Chroma.
