I haven't had any luck with this so thought I'd ask in here.

The thunderbolt cable for a razer core x chroma, they're not proprietary at all are they?  I'm reconfiguring my desk layout and the cord I have is super short.

I'm going to buy a new cord but don't want to jump the gun so want to make sure there isn't a specific one I need or anything first.

Cheers

@sledgy84, No they are not proprietary.

But in saying that, not all Thunderbolt 3 cables are made equal. Most short cables (under ~0.8m) are passive cables. There are also longer passive cables, but they are usually restricted to 20Gbps, USB 2.0, ETC. To get full speed at lengths over 1 metre, you need an active cable. Furthermore, some manufacturers state their cables have Power Delivery limits (65w vs 100w, etc). Some cabled are certified by Intel, others are not. It is a bit of a mess to be honest.

I would purchase a Thunderbolt 4 Cable, which is essentially all the highest end possible options from Thunderbolt 3 guaranteed.

I use the CalDigit TB4-A20B-540. It is a two metre, Intel certified active Thunderbolt 4 cable and provides me with maximum H2D bandwidth speeds to my Aorus Gaming Box.

Cool so as long as it's thunderbolt 4 I should be sweet which conveniently I was looking at anyway.

For this, speed is def a must as I do a lot of video editing and it's the sole reason I got an egpu.

Shame about the cost of some of them but hey, gotta do what you gotta do.

You just need a TB3 cable with a "3" shown on the connector edge, like shown below. This indicates it's a 40Gbps certified cable. Without this marker, the cable will transmit at 20Gbps as discussed at https://egpu.io/forums/builds/acer-aspire-v17-nitro-black-editionakitio-nodegtx1070-win-10/#tb3-cables
