Re: not enough power?
Wow, don't think computers these days use a 120W power supply. I would double it. Get a 250 W power supply. It depends on what compnents you have in your system. If it's a power system, more would be better. If what you have now is mediocre, than a 250W is just fine.
*Fact: Microsoft Window's Blue Screen of Death vs Computerforums.org's White Screen of Death. Which is worse?
