US$200 Chinese Domestic Market Thunderbolt 3 eGPU

I recently came accross this two Thunderbolt 3 External GPU Enclosures that are extremely cheap and have some interesting features that would suit a budget eGPU build.

- Standard ATX Power Supply Mount. 
ATX Power Supplies are extremely cheap and can be purchased or salvaged second hand for even less, and are globally available. Furthermore, they can provide enough power for any GPU.

- Includes an open half-case, that can be used as is, have a custom case made for it or even mounted under a desk.

- Includes a jumper pin that is apparently designed for the use of NVIDIA cards with Bootcamp (Although I have no idea what this actually does).

 

Two things to take into consideration: I am unsure of what Thunderbolt Controller is being used in the enclosures and I have no idea of what Thunderbolt 3 power delivery (if any) they have.

 

The first model is branded as Wikingoo:

There is another version, branded as Vikinyee, that has a slightly different PCB (No red power button).

If anyone has any information or experience with this enclosure I would love to know.

At the time of posting this, the enclosure can be purchased for $254.14 AUD (187.65 USD) delivered, making it only slightly more expensive than the R43SG-TB3.

@boltoway, I don't know if the savings would be worth it once you add a power supply. In one of the reviews, I saw a screen capture in macOS that shows the Thunderbolt mainboard identifies itself as TB4 eGFX, Vendor ID: 0x215, Device ID: 0x41. What I find interesting is the jumper header for card optimization. I think it has something to do with delay booting to prevent firmware compatibility issues with some Nvidia cards and Macs.

@itsage,

I think this eGPU would be particularly suitable for someone who already has salvaged or spare ATX PSU.

In saying that, even a modular Corsair 650Watt PSU can be acquired for under $100 AUD, bringing the total to ~354 AUD. The Razer Core X, for example, retails for around $540 AUD. While it definitely isn’t as pretty as the Core X, I personally prefer its half-case to the R43SG-TB3.

Do you have a link to the reviews? I would be interested in reading them.

@boltoway, It's a good option if you already have some components. I'm curious what the Power Delivery is on this unit. It's one of the selling features of Thunderbolt 3/4 eGFX. The review I referenced is from a customer in Columbia. He posted a few screenshots and one of them showed the Thunderbolt mainboard IDs.

Saw this one before and skipped it prior to supply chain issues thinking (1) lack of PD advertising means it's likely only 15W bus power and (2) it was going to find tough low cost competition from the ADT-Link R43SG-TB3 and Sonnet Breakaway 350.

ADT-Link R43SG costs less and is more flexible, as described at: https://egpu.io/forums/thunderbolt-enclosures/adt-link-r43sg-tb3 , copied below:

Spoiler

ADT-Link R43SG-TB3 (or equivalent) offers a lot of flexibility

 

1.  Inexpensive - costs significantly less cost than a TB3 enclosure as seen in the Buyer Guide

 

2. Can host an unlimited GPU size

 

3. Can use a ATX or Dell DA-2 PSU for input power

 

4. Optional: once sized up with (2) & (3), can build a custom enclosure around it

 

5. My favorite:  can use the eGPU adapter either with a higher-performance M.2 slot or TB3 port.   Or mix and match.

Choose which device (eGPU, NVMe SSD) will use which port (TB3, M.2). You do not get such a choice if buy a dedicated TB3 eGPU enclosure. Though this is more relevant to PC than Macs.

 

6. If not being used to host a TB3 eGPU, the NVME-to-TB3 adapter (CY/cablecc) and 50cm TB3 cable components can be used to host portable, fast external NVME SSD storage.

 

Though now it might make a lot more sense. In-the-know users might seek out an ebay Sonnet Breakaway box and flash 87W PD firmware onto lesser units using tbt-flash to get lowest cost and maximum functionality.
