Custom PSU SATA CableS

[Vicariously]

I am trying to make custom SATA Power cables for my many drives and devices. I have a power supply tester and voltmeter. I have made the cables following a guide and made sure that the power goes to where it is supposed to (GRND to GRND, 12V-12V etc). I have tested it with single drives, (SSDs and HDDs) but there is just one problem...my RAID drive does not power on with this cable.

 

There is only one thing I left out of my cable after reading some forums and that is the 3.3v line. I found out through research that this is not even really used anymore. I bought a splitter that appears to not have the 3.3v rail to test it with a cable that came with my PSU, and sure enough, the RAID works fine using the splitters that do not have the 3.3v line. But when I connect the cables I made, that also do not have the 3.3v line, it doesn't work.

 

I'm kinda lost right now. I'm not sure why my cables aren't working ONLY with the RAID setup, they work fine with SSD's on their own, my fan hub, my AIO Pump everything, but it wont power on my RAID.

 

Does anyone have more experience than me and can possible shed some light on this? 

 

My RAID SSDs are 1tb Samsung 860 EVOs, my custom cable has successfully powered on a Kingston SSD, another Samsung 860 EVO, a WD Black 2tb Drive, a Corsair AIO, and my case's built in fan hub.

Thanks for the info, I will review and let you know if this solved my issue, after a brief skimming i think it might just be....

Do you have any other ideas, I read the information, and I even added the 3.3v line to my custom cable, and still for some reason it doesnt work with my raid. it works with every other device, and works with drive individually, i thought it was an issue of power consumption but it even worked fine with all connectors powering HDDs I have no idea what could be preventing my raid from working when using my custom cable. 

 

The voltages read out properly and nothing is shorting, the raid works normally when using the factory supplied power cable or power splitters..i dont get it!

I think you helped me a lot, and I don't know if this was the fix in the end. I essentially just re-made the cable from the ground up. My cable does have a good amount of soldered joints in it (very custom application) and i think maybe one of the joints was bad in the first attempt. Thanks for the help, and it sucks that your comment wasn't the easy fix. Guess I'm salvaging the old cable to re-use later
