SATA/IDE power supply? ?

Hello Anybody, 

I’m apologising in advance for this post, because to some it is probably such a ridiculous and basic question, however. I have an extremely old IDE 3.5 HD I’m just wanting to remove old files from. So I jumped on eBay and brought a basic USB to SATA/IDE converter, not realising my HD needs a power supply also. Having only the adapter and no power supply, how can I get around this? 

Would a Molex to SATA cable help me achieve this or not? 

Thank you for the understanding and any help/assistance! Much appreciated. 


My logic is - buying the Molex to SATA cable and plugging the SATA End into the ide/SATA adapter I have, then the Molex End into my HD - would this give the HD enough power to run from the SATA/ide to USB adapter? If that makes sense 🤨

    you need a cord that is designed for this specific purpose.

    which converter did you buy? many have a place for a power adapter on it.

    otherwise, this should work if your drive is SATA:

    if it is IDE, you will need this:

    If you just have the ide to usb adapter, simply plug the molex from your computer's power supply directly into the old hard drive you are trying to power up.

    You need a powered adapter or like I use an external HDD case. Has external power and IDE/SATA interface to USB.

    Used it on my 3.5 and 5 inch drives to backup files.

    Now those old high time drives are wiped and dumpster fodder.

    Kits like this one have both the PATA and power included.

    no, no, no. just open the case and use on of the spare molex leads. after all, this is a temporary measure

    yes, an adapter would work to power the drive. i've done this before just be careful to put the drive on a level surface that doesn't shake this can be harder than it sounds with the shortness of Power Supply Cables. if anything, you can remove your computer's power supply and plug it in..
