I am building a server. The case I have chosen comes bundled with a 400W PSU. I am certain that the PSU will power the server. My question though, is will I be overburdening the PSU? I have always been of the opinion that it is better to go with a beefy power supply and underutilize it. If someone wants to provide a technical answer, that would be great; however, what I am really looking for is a reality check. Am I being overly sensitive?
