  1. If you don't have a GPU, then you should be good with a 500w PSU, if not less. If you do, then we need to know what it is.

    In that case you should still be OK with a 500w PSU, but you might want to bump it up to 550. If you plan on overclocking then you may want to consider a 600w, but you definitely won't need more than that.

    500w.

    I have no problem overprovisioning a PSU a bit. Say 20%.
    It will run cooler, quieter, and more efficiently in the middle third of it's range.
    A PSU will only use the wattage demanded of it, regardless of it's max capability.

    650w will not be much more expensive and will permit you a future upgrade to a very strong graphics card.
