I had one of these to drive the SSD in my music server from a linear power supply but I can't find it. I do have some XLR's and also some sata plugs with cable attached, so I thought I might have a go at making my own. The XLR's are with 3 "prongs" and my sata cable has the usual 4 wires. 

Diagrams would be great and probably essential as a 2tb SSD isn't cheap and won't survive a cockup I imagine. colinf

Hi Rocl!
Is the XLR standard connections? Normally an audio XLR connection has pin 1 as ground, pin 2 as + and pin 3 as -.
Sata drives need both +5v and +12v. Pin 1 is 12v (yellow), pins 2 and 3 are ground (black) and pin 4 is 5v (red).
Can you ascertain the pin connections on the XLR on your linear power supply? You can use a multimeter to measure it if needed. Pin 1 is likely to be ground but not sure which pins they used on 12v and 5v lines. Connect both black ground wires together.

Thanks Colin - it's for an SSD so the 12v is not needed. It wasn't on the cable I can't find. After I posted this I did some searches and instead of searching for the cable I searched for each end. Yes I know - I'm getting old. So I found diagrams of the sata power end and the XLR end. My power supply is standard - pin 2 is +ve and 3 is -ve.

After 3days I have managed to get the server feeding the SMS200ultra and the difference in sound over a powered usb HDD was amazing. The lan port on my old one died. Those little fanless units from China are excellent for the job. I have a spare 5v slot on the power supply so I might as well use it.

Good you got it going.
Just goes to show what a difference power supplies make, even to the SSD. Less noise on digital sources means less jitter so I imagine it would sound smoother.
