    Yes, it matters which one you buy.

    Older motherboards use a 20-pin ATX connector, while the newer ones use a 24-pin ATX connector. You can use a 24-pin power supply with a 20-pin motherboard by attaching an adapter, but you can't do it the other way around. You might also need to make sure it will fit properly into the case. Make sure the wattage is high enough to handle all the devices that will be plugged into it. Make sure that it has connectors for all the different types of peripherals that will be plugged into it.

    Have fun installing your new power supply.

    Also, take it from someone who learned the hard way -- do not buy cheapo, "bargain" PSUs.

    Here are the brands I've personally had OK experiences with, FWIW: Ultra, Thermaltake.

    Good point! The old rule of thumb regarding computer power supplies is to buy the best one you can afford.

    Yes, I should have made it more clear that it is possible, but generally not recommended.
