Well, my bad. It was an Antec Earthwatt 380W PSU. :p And yeah, it can handle up to 3.8GHz and with the 9800GTX slightly overclocked. Anything above that would prove to be quite troublesome (a.k.a. unstable) so in the end, it works out pretty well, I guess. I'm out of my budget for a better PSU (since my college is asking back like half the total value of my PC for whatever reason) so this will do for now.
