It only seems to look scary, but with 450W power supplies out there for 20 bucks or so, why skimp?
The PC will only draw what it needs and the extra size is usually more efficient, runs cooler and can cushion against power loss if the AC vanishes for a few more cycles.

I am planning to upgrade my power supply from a 250W to 300W or higher. It looks pretty straight forward for installing the new one. Is there anyspecial that I should know before I start?
