So now I am not sure if I got the wrong cable as the description is not super clear. Also, I did go back and did some more testing, in short, just plugging the cable into the power supply, without attaching the disk, will cause the motherboard not to boot. Fair to assume it is not a load issue, yet.
With that being said, I am looking for other power supply options, but do want to check one thing, can the cable for peripheral power be used with SATA drive, with a Molex to SATA adapter of course
