    Hiya guys,
    I have a pair of hard drives, and in an effort to tidy up the desk space was looking at removing one of the power supplies and just adding a double adaptor on the end... Bad idea.
    Both adaptor specs are as follows,
    Each are 12v 2A output, from 100-240v~ at 47-63Hz with 0.65A Max.

    I was wanting to condense two HDDs into the one PS. But upon measuring the input current, which turned out to peak at 0.7A and stabilise at around 0.5A.
    I'm thinking this would cause an overheating issue if i was to use only one.

    So would changing to a 12v/4A adaptor work for this, or would I need to go for a larger one?
    This is with attaching connectors into the adaptor when it works.

    If you have 2 x 12V (2A) adapters then a single 12V (4A) will be just fine for powering both. But I would not use the single 12V(2A) for both.
