It depends on the total length of the cable, the number of connectors, the current capacity of the PSU connector it will be plugged into, and the kind of drives that will be plugged into it (HDDs draw considerably more current than SSDs). The largest number of connectors I recall seeing on PSU cables is four, using #18 AWG. You probably can get away with one more on that wire size as long as the cable wasn't any longer. Any more than that, you would probably want to go up to #16 or maybe even #18, depending on how many more you add.

Guessing, 12-18inches total length, total of four 2.5 SSD's

Anyone have preferences on sata power connector type vs connector/terminal?

Could you use this crimp style with Paracord?

The second one? Yes. However, it makes for a bulkier cable. Ladder style with the first connector linked will look better.
The one in my first link? No. You could superglue the end of the sleeve to the wire but, if you are putting them on the cable ladder style, it would look better if the wires between the connectors weren't sleeved.Originally Posted by knightsilver

Yes, the first link. No sleeving on the ladder, sounds less BS, just go with black awg.

Four stacked 2.5 ssd's. Yes, Himo5, the above pic is what I'm wanting, just not sure on spacing.

Maybe these two worksheets will help. The real problem to watch out for with inline sata power cables is how firmly the wire in every connection along the chain is in touch with the contact blades. You need to arrange a really good prodding implement that is going to push the wire right to the bottom of both slots simultaneously without slipping through one of them and ruining your measurements. You then need to test every contact along the chain with a multimeter before applying any glue.

I like the first connectors too. They are flippable so you can secure them for whichever cable orientation works for your build too. But the second one is great for single drive connectivity where you have your drive(s) mounted behind the MB tray and no other drives powered via dthe same lead. Makes it easier to cable manage as well in both circumstances.

The no sleeving on the ladder, guessing only 3-4inches on the ladder side, and just go bare black 18awg wire.

They are durable in use. It's just easier to break them when punching down the wires if you don't do it properly.Originally Posted by knightsilver

An easier way would be to use a sleeve that is just a hair smaller than the wire, then cut it to the needed length with a hot knife blade. That will singe the ends and let it slip over the wire without the need for a heat shrink to prevent unraveling.Originally Posted by Himo5
