wiring issues with a build

[dragonfly52277]

There is a simple answer I presume but I am wondering if there is a simple way to know why I shouldn't use a single cable to connect the power to multiple storage sources. I was putting together my own build and it started smoking (yikes!) . I separated the cables into each storage device and it works fine now. Is there a simple way to tell what instances there are where I can use a single cable for both storage sources? I don't mind using separate cables; I just want to know why it started smoking. Thank you in advance.

First thing that came to mind... Right now I have 6 HDDs hooked up to one lead, there are three SATA ends on the cable from the company, and each one has a splitter on it. No smoke. 2 HDD/ODD/SSD shouldn't be that much of a pull on the PSU that there's gonna be smoke. HDDs are like 5w, ODD 12w, SSD 3w, something like that, I know my numbers are off, but the point is the same. Unless you've got stuff majorly overpulling from your PSU, there shouldn't be smoke. Ever.

can be you cracked the sat power or data cables connector without knowing it or bent two power pins together. the cables you have were miss wired. or if a new power supply the power supply cable for the ssd are wired wrong.

if all the new sata drives are doing this it may fry one of the newer drives using a 4 pin splitter cable.

@smorizio and jossrik - ok, ty for the response, and yes ..I suppose that there may have been a wiring issue. Using separate cables for the HDD and the SSD did the trick. And I don't want to duplicate the same problem to isolate the problem before it does something worse. I'll jus have to b more careful.
