Not sure which subforum this is best for, so here goes.
I'd like to power couple a u.2 nvme ssds in a chassis where this is not possible. The only place you could get power for anything the manufacturer didn't specifically design for, is the pcie bus.
The server supports 75w draw for gpus in pcie slots, so there's a decent amount available. Even the lower pcie 25w draw limit would be acceptable for my anticipated use.
Question here is, can a pcie slot deliver 5v, or only 12v? To my understanding, sata devices commonly require both, and of course molex supplies both voltages as well, so it's possible u.2 expects this voltage available as it uses a sata power connector. If pcie only supplies 12v, I can see why I haven't been able to find an adapter for this up to now.
Has anyone been able to do this before? Are you aware of a product to convert a spare pcie slot to either a molex or sata power adapter. I've looked for a while and can't find anyone talking about this, let alone selling a product for it.
