Electrical Characteristics
All power is supplied to the Intel
®
Integrated RAID Module RMS2MH080 through the
board-to-board connector via PCI Express* 3.3 V rails.
The supply voltages are 3.3 V ± 5 percent from PCI edge connector only. The maximum
power for the +3.3 V rail is 18 W. The +12 V rail is not provided by the base card. The
+3.3 V rail is used by the 3.3 V logic circuitry and also used to generate the other required
voltage rails of +1.0V, +1.2V, and +1.8 V. The +3.3 V auxiliary voltage is used to generate
the +12 V standby for the Intel
