I wouldn’t want to find out the hard way. I have a BMD decklink 4k mini monitor PCIe card. I used to use it in a PC, but I upgraded to a laptop. To replace with an external input device is too expensive unless I downgrade capability significantly.
PCIe chassis are more expensive than expected but I’ve noticed ones that specifically call themselves ‘eGPU enclosures’. For some reason when they’re marketed to that specific purpose, they cost a lot less, probably because they often don’t come with power supplies (which I actually have spare).
I’m looking at 2 such eGPU enclosures and they are a decent price and I think they should work, but I’m a little scared by them specifically saying “eGPU”. Would I likely have any problems buying one of those for my PCIe device rather than for a graphics card? Or is PCIe, PCIe regardless?
PCIe is PCIe regardless. It should work, just be careful with unplugging things that aren’t hotpluggable, both from the card itself and the cable.
I’d take the chance personally. I’m sure there are edge cases though, but I’d bet on it working.
