Hi, I have found this low-cost configuration, buy new with 2-year warranty on gpu and a budget around 250 €:

 

System specs:

MacBookAir8,2, Dual-Core Intel Core i5, Intel UHD Graphics 617

macOS Catalina 10.15.7

 

eGPU hardware:

be quiet! TFX Power 2 300W 

ADT-Link R43SG-TB3

Sapphire Radeon RX 570 Nitro+ 4GB GDDR5

 

To save money I'm using a low profile TFX 300 W non-modular power supply + PCIe-TB3 all-in-one adapter with no enclosure and no fans.

I can hide cables behind my iMac on the same desk. I don't need much more than this, I hope this will work.

JMS583 is USB. It can't do PCIe between CPU and GPU. It's a USB device using USB mass storage protocol. The USB device communicates with the NVMe/PCIe device to do NVMe reads and writes. You can't use USB mass storage protocol to talk to a GPU.

You need Thunderbolt. It can do PCIe between CPU and GPU.

Do I need the adapter with R43SG-TB3? I don’t need eGPU on Windows, I have only Apples. Thanks.

@francesco_ripa, that will work. Or any other Thunderbolt solution...

I have actually found this after purchasing the R43SG-TB3 adapter.

He's using the exact M2 to TB3 adapter [JMS583] with a RTX 2060S on a MacBook. Is it fake?

Orico makes many transparent NVMe enclosures. Only the ones that connect via Thunderbolt (20 or 40 Gbps) can be used for GPU.

The JMS583 one (TCM2-C3) is for NVMe (socket 3, key M) to USB 3.1 gen 2:

https://www.orico.me/product/nvme-m-2-ssd-enclosure-10gbps-tcm2-c3/

The JMS580 one (TCM2F-C3) is for SATA (socket 2, key B) to USB 3.0:
https://www.amazon.ca/dp/B082TZ8DB2
https://www.orico.me/product/ngff-m-2-hard-drive-enclosure-tcm2f-c3/

The RTL9210B one (TCM2M-C3) supports NVMe (socket 3, key M) and SATA (socket 2, key B) to USB 3.1 gen 2:
https://www.amazon.com/dp/B08PFSBJF6
https://www.orico.cc/us/product/detail/7143.html

The one shown in the video (TCM2T3-G40) is wider and has a Thunderbolt icon. It supports NVMe (socket 3, key M):

http://www.oricothailand.com/store/orico_en/usb-c/tcm2t3-g40.html

The one on the US amazon website doesn't have the Thunderbolt icon.

I'm not sure why they say the Thunderbolt ones do not support AHCI since that is also PCIe - maybe a power issue?
