If you buy that Cougar unit, also buy a fire extinguisher and put a piece of concrete between you and the PC strong enough to absorb an explosion.
If you would instead like to prevent your house from burning down, I would recommend either a Thermaltake Toughpower GX2 if you need to save a buck ($65 bucks on Amazon), or a Silverstone Strider ($100 bucks on Amazon) if you are willing to spend a lot more for quality. If these aren't available in your country let me know and I can look around some more.
In general, please don't cheap out on your power supply. You end up not only creating a hazard for yourself, but you run the risk of turning your PC on one day and frying every single component.
