Ultimate one cable solution? Some user experience of Razer Core X Chroma and Gigabyte Gaming Box

Hey guys, I'm looking for an eGPU enclosure which could provide a perfect one-cable solution for MacBooks.

Here is what I think an one-cable chassis should have:

1. 100w power delivery. 85w should be fine, while as you know new MBP16 is jumping to 100 watts now.

2. USB ports. Or if there is a second TB3 port for daisy chaining is OK.

I know there is a buyer guide here, actually I have been using Razer Core X Chroma for several months, and I was switched from Gigabyte Gaming Box RX580 before. While these two chassises do have some problems which don't show on paper that is really annoying.

First I want to talk about Razer Core X Chroma. That chassis is perfect on paper, 100 watts PD, 4 USB ports and a bonus ethernet jack. While that USB ports have a serious problem: they don't support any USB hub connected to them, even powered hubs. If you connect an USB hub to it, all devices on hub will constantly disconnect an re-connect. That means your number of usb devices is limited to 4. Because I have multiple audio devices connected via USB, I have to connect a second usb cable to my laptop for a hub. That ethernet jack is also not usable under macOS. The driver for macOS is really broken, any slightly heavier network load will cause a driver failure which only reboot can fix (windows driver is fine by the way).

OK, Gigabyte Gaming Box is also perfect on paper, 100w PD and 3+1 USB ports. After receiving it, the first problem I've noticed is noise: that small fan in fATX power supply is really loud, and it never stops with TB3 cable connected, even laptop is shut down. Then I followed a topic here, replaced that 40mm power supply fan with a quieter one. Another problem is, with any USB devices connected, those 2 side fans sometimes do not spin at all (RGB also doesn't light up by the way, that 2 side fans and RGB lighting might be sharing some bus with USB ports in some way), and that chassis gets very hot. This problem finally lead to a fatal result, the power supply might got a temperature sensor failure and the power supply fan spin at full speed all time, which sounds like a jet plane. That's why I switched to Razer.

Now I regret a little for I sold that Gaming Box because I realised that I could transplant that board to an ITX case with a proper SFX power supply, at least those USB ports function better than Razer. Roll

@lilipeipei, I don't think it is a good idea since it will eat up your bandwidth, hence lowering your eGPU performance. What I heard is that the best would be eGPU plugged on one side and peripherals on the other. I'd recommend getting a USB hub so you will have a two plug solution.

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@ana-satsujin, actually that's the way that I'm using now, an USB-C cable for USB hub and a TB3 cable for eGPU. However, that means I paid extra 200 AUD just for RGB lighting 😂.

I know extra ports would suck up some performance, while I'm not using that eGPU for gaming (you know macOS is not really good for gaming). I just need an eGPU to do some light video decode acceleration and power up a 4k monitor. dGPU in my MBP2016 is kind of suffering during my daily use because of the poor thermal design.

I have a Razer Core X Chroma connected to a MacBook Pro 15" and I have several drives connected to the 4 USB ports + 2 USB 3 hubs and use an external DAC connected to one of those USB ports. 

Not a disconnection issue to be fair.

I have a problem with some HD not powering down at shutdown lately, but that is caused by a powered USB hub (I described this in another thread).

No bandwidth issues so far to be fair. I don't use it for gaming.

Yes, the ethernet port is unusable on Mac (disconnects continuously) but I use the one at the back of my monitor.

@er-minio, Great to hear that not all Core X Chroma have this issue. 

 

May I ask have you did any firmware update? Which powered hub did you use? Thanks

@lilipeipei, not 100% sure if the firmware has ever been updated as I bought it used from a friend a couple of months ago.

The powered hub is this: https://www.amazon.co.uk/gp/product/B07RK4KL8H/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I have a minor issue with it, explained in another thread.

This is my current setup, and apart from what explained in the other thread, everything works fine:

This is from system profiler, if of any help:

@er-minio, Why is the connection from the MacBook Pro 15" Late 2016 to the Razer Core X Chroma only 20 Gbps? Bad Thunderbolt 3 cable? Or are you using a USB-C cable instead of a Thunderbolt 3 cable?

Cable lenght.

I use this: https://www.amazon.co.uk/gp/product/B01AS8U8PU/

The way my computer setup is "built" I need a longer Thunderbolt cable to reach the laptop.

I realised it was a 20Gbps cable and not 40 long after purchasing it.
I'm new to this and didn't know there were slower thunderbolt 3 cables, so I completely "ignored" the data in the title Smile

Gonna replace it soon with this: https://www.amazon.co.uk/Cable-Matters-Thunderbolt-Supporting-Compatible/dp/B07B7CQ83V/

Little update. I replaced the Thunderbolt cable, all peachy.

The Chroma purrs perfectly, did some light 3D work, used some GPU intensive software for work, all good.

 

Then, I bought Civilization VI.

Man, I wasn't expecting it to stress the GPU so much. 90% usage all the time. Anyway, the problem I have is I'm getting horrible crashes because the Razer seems to be disconnecting the USB bus after a while running hot-ish and it seems also it sort of disconnects itself...

Not sure where to start to investigate this.
