There is a lot going for the CoolerMaster Extreme 2 450W for non-power users.  It costs under $50, it is not much bigger than the 120mm fan that cools it and the 450 on the side offers enough power for many systems.  Unfortunately once Hardware Secrets opened the box and tested this PSU they would like to remove your misconceptions.  The 450 is not actually the wattage but the model number and this is, at best, a 425W PSU and the quality of power they observed from their tests is abysmal with ripple and voltage drop both exceeding specifications.  This is one PSU they recommend you avoid at all costs.

"The new Extreme 2 entry-level power supply series from Cooler Master comes in four different versions: 475 W, 525 W, 625 W, and 725 W. They don’t have an active PFC circuit and, therefore, don’t carry the 80 Plus certification. Let’s take an in-depth look at the 475 W model, which costs only USD 50."
