    I am wondering how many hard drives a single power cable can handle. Here is a theoretical example to try and explain what I mean. Let's say I have 5 hard drives in my computer. I need them to be able to all be plugged in, but only have 1 power cable available from my PSU. The power cable has 2 plugs on it, and I have 3 Y-Splitters (if I plug 1 splitter into each plug on the power cable and another splitter into one of the two, then I would have 5 available plugs total, all on the 1 cable). Will this one power cable be able to support the needs of 5 hard drives running at the same time, or must I get more cables from the PSU? I just need to know how many drives per cable are workable. Not sure if this made sense, but hopefully someone will understand and know the answer. Thanks.

    I would say you will be able to run 5 drives , but just wondering what PSU and wattage is it?

    If the PSU has 2 plugs on one power cable then there is a reason its like that. do not overload.

    you might be lucky if the drives survives with the y-splitter.

    For Case fans its ok to split it, so if you have any plugs going into case fans split it with the y-cable, use one for hdd and other for the case fan. hope it makes sense.

    I could probably get another cable (so 2 coming from the PSU), but even then I would have 1 cable with 3 drives (which would require a splitter). Also, the reason I posted was because I wasn't sure if the cable only had 2 plugs due to power, or just the fact that the cables get VERY long after 2+ plugs on it.
