Im pretty sure my power suppply has gone bad. My hard drive keeps spinning down then the computer freezes. Cant even get windows to fully load.
Im planning on upgrading my computer to a i7 2600k build within a year and want a power supply that can carry over. I will still use my GTX 460 in the new build and may buy a second for SLI. I wont be buying any additional hard drives though i may replace my main drive with a WD Black.

Buy the biggest QUALITY PSU you can afford. What you call "extra capacity" is an insurance policy, and a cheap one at that. PSUs are the most overlooked (and overworked) part of nearly all computers. Running a PSU at or near capacity will eventually cause premature failure and may cause any number of undiagnosable problems along the way. It's money well spent, not wasted. Unfortunately, you'll never be able to thank me for the problems you never had. :-)
