  • A connection for the power cord to the computer.
  • In ATX-style systems, the front-panel power switch provides only a control signal to the power supply and does not switch the mains AC voltage.
  • When the power factor correction (PFC) was required, those filter capacitors were replaced with higher-capacity ones, together with a coil installed in series to delay the inrush current.

From a performance standpoint, both work equally well; and in general both are very safe to use. A power supply with a 24-pin connector can be used on a motherboard with a 20-pin connector.
