Power Supplies

  • Convert AC power (120v, 240v) to DC power

  • Provide required voltages:

    • 3.3v
    • 5v
    • 12v

  • Not typically programmable

  • Proper function is critical to system stability

  • Help protect against voltage fluctuations

  • Not a full surge suppressor

  • Choosing high-quality power supplies is important

  • Poor power supplies can cause system damage

  • More vulnerable systems:

    • Desktops
    • Server towers
    • Rack systems
    • Standalone systems

  • Less vulnerable:

  • Laptops (use internal battery during power issues)
