  PCI Express Power and Mini Card Solutions – Design Note 346
  Mitchell Lee and Vladimir Ostrerov
  Introduction
  PCI Express is the third generation of PCI (Peripheral
  Component Interconnect) technology used to connect
  I/O perhipheral devices in computer systems. It is
  intended as a general purpose I/O device interconnect
  that meets the needs of a wide variety of computing
  platforms such as desktop, mobile, server and communications. It also specifies the electrical and mechanical
  attributes of the backplane, connectors and removable
  cards in these systems. PCI Express Mini Card also provides two power sources:
  3.3V and 1.5V. The auxiliary voltage (3.3VAUX) is sourced
  over the same pins as the primary 3.3V supply and is
  available during the standby/suspend state to support
  wake-event processing on the Mini Card. Table 2 summarizes PCI Express Mini Card power specifications. Power Requirements
  Each add-in card connector requires two power rails:
  12V and 3.3V, along with a third, optional 3.3V auxiliary rail. If the designer elects to provide the auxiliary
  3.3V rail in his system or if the platform supports the
  WAKE# signal, the 3.3VAUX rail must be supplied to all
  connectors. Table 2. Summary of PCI Express Mini Card Supply
  Requirements In PCI Express, as in PCI, the Hot Swapв„ў controller is
  resident on the platform side of the system, delivering
  power to the connectors only after a card is inserted. …
