I just recently built this, and I've been having some issues that I'm guessing have to do with the power supply based on some internet research. The system will sometimes do a full reset, as if I pushed the reset switch.

I'm thinking maybe my power supply doesn't have enough wattage. I used a build recommended by Lifehacker, except I used a different video card (same processing chip, different manufacturer - uses 50w more power than the other one). I also have 8 gb more ram and a wireless card, but they don't seem to make much of a difference in terms of power.

Any help with troubleshooting this issue would be greatly appreciated :)

Edit: It's probably worth noting that this problem has come up within the last week (I've owned the computer for almost 3 weeks).

Yes, It is absolutely your psu, because sometimes, under heavy load, your system will require more power, and that is when your system goes down. Switch for a 650 psu and you´ll be fine.
