    Hi - There is no harm in having a 750w psu when you only need 500/550,
    other than the additional cost initially.

    The harm however is a poor quality PSU vs a good quality PSU
    such as the XFX rolli linked. Be sure if you purch a PSU
    of any wattage that it's a quality brand/model.


    quality brands: Seasonic, XFX, PC P&Cooling, Rosewill Capstone series,

    most Corsair's, most Antec's, Enermax, and a few others.
