    I've placed several orders over the past couple of years and Discount Electronics always meets my expectations. Customer Service (especially Jesse) is top-notch and will go out of their way to make sure things are right.

    As far as the power supply -- it's a power supply. It works. :)

    Discount Electronics is a great company.
