very possible. many times its not just the overall wattage, but the
wattage on the different voltage rails. It's the reason a lot of the
gamers buy incredibly over powered power supplies, because they need
something that has a specific amount of amperage on one of those
rails.

that said, Seasonic makes some great power supplies, so if your taxing
it on one of its rails, you should replace it soon before you fry the
transistors in it so you can use it in another system.
