Don't use that PSU. This is the most important component in your system. A crappy PSU such as that one will not provide your system with clean, stable power. Also if it fails there is a very good chance it will take other components with it.
Get a quality PSU from Corsair (CX400, VX450), Antec (Earthwatts 380, 430), Seasonic, PC Power & Cooling, or Silverstone.
