oculink power

[FrankTL]

Looking at converting an Oculink port to M.2 NVME, and NFHK sells convertor boards doing this through Amazon and ebay (eg: Pardon Our Interruption... ).

However, the images got me thinking: There's no external power input visible! Which means this will power the M.2 drive strictly through the Oculink port.

Does anyone know the max power that Oculink can deliver? I don't want to risk frying my motherboard/Oculink port.

Edit: hmm this site says no power rails on Oculink: PCIe For Hackers: External PCIe And OCuLink

I have a oculink hba from supermicro; it doesn't provide any power and and the endpoint (in my case a u.2 backplane) has to provide the required power.

Ok that's odd. Maybe there's a power connector on the underside of the PCB, not visible in the pictures.

Only one way to find out: I've ordered the NFHK convertor.

So, what's your conclusion then? I am struggling with the same issue here. I invested in two very expensive NVMe drives, only to realize that they are not detected by the system, and very likely because the NFHK adapters do not provide power.

I received the adapter but it doesn't have any external power input. It's in a drawer for now as I cannot imagine this working.

I think NFHK did not look at Oculink specs when designing this adapter, let alone do any QA on it

Maybe this or this might work?

Yes those might be a better option (ie it may actually work).
