2.5 Electrical Characteristics
The PCI Express* Specification requires that the 12-V rail and the 3.3-V rail have a voltage
tolerance of 8% and 9% respectively. The amount of power that an adapter card can use is also
limited.

All power is supplied to the Intel
®
RAID Controller RS2BL080 through the PCI Express* 3.3-V
rails and the 12-V rails. The on-board switching regulator circuitry, operating from these rails,
provides the necessary voltage. The following states determine the typical current consumption
of the controller:
provides the necessary voltage. The following states determine the typical current consumption
of the controller:
State 1: Battery is charging
State 2: Battery is full
State 3: Battery is discharging
The supply voltages are 12 V ± 8 percent from the PCI edge connector only and 3.3 V ± 9
percent from the PCI edge connector only. The following table lists the power supply for the
RAID controller for each state at the different voltages:
