Comment on Small Unraid PC with 2 HDDs. Silverstone SG13 case with Asrock N100DC-ITX, the SATA power cable was too short so I had to improvise.

  You can also build your own custom SATA power cables with some crimp connectors. a.aliexpress.com/_mszyiNO

  Thanks for the tip! For some reason I was searching for a similar but longer cable to the one provided but never thought to look for a SATA power extender :).

  I’ve heard about avoiding the injection molded ones but I wanted to ask you, is it safe to power the 2 drives directly from the motherboard? The board has 2 SATA ports and the cable that comes with has 2 power SATA connectors so it should not overheat/burn the cables if they give you the option to use it? This is the board www.asrock.com/mb/Intel/N100DC-ITX/#Specification

  I live in a constant fear of batteries catching fire, cables melting and other bad things happening when it comes to power :). That’s why I tend to only buy original batteries, cables, power adapters.

    The risk was poorly-made power adapters, where 2 pins could short/arc. These cables were almost exclusively injection molded and sold through cut-rate outlets like Ali Express (and Amazon resellers of them).

    Technically crimped cables are not immune, but they are rarely seen with such cost cutting. Quality molded cables are also fine, but that is very difficult to recognize or verify after purchase.

    The manual should tell you the power limits, and you can cross-reference the power usage of the drives. It’s probably ok for normal consumer drives, but high-draw or enterprise drives could be an issue. You could also (probably) just get power from the PSU.

      Unfortunately it doesn’t say in the manual. It only says that if you use 4 HDDs you should use a 90W DC 19V power brick. I already ordered one, my confusion was if the 4 pin cable supports 2 HDDs but I guess since the board has 2 SATA slots and cable also has 2 SATA power connectors. I plan to most likely use 2x WD Red Plus 8TB, they use 6.2W (load), 4.1W (idle)

    If that’s the stock part, seems like it would be within spec. You can check the manual or detailed spec doc to be sure.

      Also posted this above to a previous poster but you won’t be notified so I will post it here as well.

        Huh. Kind of surprised it supports up to four drives, but if that’s what it says, there you go. Shouldn’t be any risk of drawing too much current through the wire. At most the board or PSU would shut down.

        Also, if you are putting more drives in, see if the BIOS lets you enable staggered spin-up, so that they aren’t all peaking at the same time.
