Does something like this exist?

[Chikensoops]

Sorry for the bad drawing. So it’s an external pcie x16 riser(or something, idk what its supposed to be called). I thought about this after thinking if my case can fit a gpu. Something like this has to exist somewhere right? Or at least something like it. Not those egpus for laptops, or those usb 3 risers for mining. The 4 tb4 ports are for all 16 lanes. Even if it doesn’t exist, would something like this work? Thanks.

No, it doesn't exist.

 

Riser cables exist. What exactly are you trying to do?

To have them outside my case, while the side panels are closed. Also since the cables are coming out the back, i just think it looks cleaner.

So it would be a 4 TB4 expansion card using a x16 interface? 4 TB4 ports coming out the back?

Or are you going more for like a TB dock with 4 TB4 ports that puts the riser through the open expansion bay slot? If so, what would be the use case for it?

Based on the drawings and the thread description, seems he wants to "rise" his GPU out of the case because it doesn't quite fit.

 

If that's the case, @Chikensoops, I think you're going to have to DIY it.
And keep in mind it's not just the PCIe cable you have to take out, you will also need to "rise out" the power cables from the PSU (If the card is too large for the case, I'm assuming it's not a low powered thingy and it does required additional 12V cables).

Yes, and then 4 TB4 cables will connect it to a riser that uses all 4 of the ports, as seen on the second drawing, so that all 16 lanes could be used for the gpu.

I see. The only way I could see to diy it, would to to just use a riser cable, and cut a hole in the side panel. As for power, I have this extra PSU I don’t use. I’m not gonna do it tho, too much of a hassle.

I am utterly confused what you're trying to do. So let me get this straight, you want a PCI-E 16x card with 4 Thunderbolt 4 ports. Then you want to plug in 4 Thunderbolt 4 cables and hook all of those cables into a PCB that has another 4 Thunderbolt 4 ports and a PCI-E 16x interface to plug in a GPU? And you want to do this instead of buying a larger case because why exactly?

Yes. And I don’t really want to do this. It was just a thought. Though if it were possible, I would definitely try/use it.

You cant probably cant even DIY it. Splitting PCIe x16 into 4 TB or USB ports that maxes out the bandwidth is possible, but combining these back to PCIe is only technically possible. Both a special chip to handle the transition between signals, but only the former exist because servers only have need for that one sometimes.

Not using TB ports (TB needs controllers etc) but there are x16 risers with narrow cables

Probably cheaper to change case though.

Damn that is interesting. Yea I won’t buy those, but good to know those actually exist
