There are many power requirements that we take for granted with the PC hardware in use today. For gamers and enthusiasts in particular, meeting the 36 amp single +12v rail requirement for most modern high-end GPUs most likely doesn't even cross our minds for those boasting over 600 watts.
In a recent YouTube video, René Grau from Cooler Master attached a SilentPro M500 500W power supply unit to a fully working Opel Astra car, attached by the battery starter.
To our surprise, the PSU not only provides 29 amps of power sufficient enough to start the vehicle, but it also delivers enough juice for Rene to honk the horn. With an energy-efficiency level of over 85 percent and a maximum output capacity of 620W, Cooler Master has surely highlighted the absurdity of the much higher PC power requirements found in today's high-end systems.
