I'm soon starting work on a powered x1->x16 riser cable, similar to the USB 3.0 cables that have been seen around the net for 29.99$. I've started a BOM, and so far for a 50 unit build, I'm up to 5$ in parts/unit, 7 including a usb 3.0 cable (12"). I have a question though, as I am not trying to waste money unnecessarily. Would more people use a sata power cable to power these, or would you use a 4 pin molex? I ask because I can get both (I've tried looking for a cable that does sata AND female molex, no luck yet). The power cable would add around another 2$, bringing BOM costs to around 9$ so far. I still have the boards to do, but in QTY's of 100 or so, I believe the total cost should be no more than 15$.
I welcome the feedback on the type of power cables I should include, I suppose I could do both, but this would add around another 2$ or so to the BOM.
Also, I am so far unable to find in-stock PCI-E x16 slots that have the card locking clip, would this be a big deal for some people? I've checked Digikey, Mouser, Aliexpress, Newark.com, and other distributors, but everyone either doesn't have, or is out of stock. I got a fantastic deal on regular x16 slots (<50 cents each) so hopefully this won't be a deal breaker. Unlike some sites, If there is enough interest in these I will order enough parts to make 100-200 of them (currently ordered for a build of 50) and I should begin design/board fab within a week or two.
