12Gb/s Intel® RAID Controllers User Guide 44
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± 9
percent (from PCI edge connector only). The following table lists the power supply for the
RAID controllers for these two states at the different voltages.

Operating and Nonoperating Conditions for the Intel
®
RAID Controller
RS3MC044
For the Intel
®
RAID Controller RS3MC044, the operating (thermal and atmospheric)
conditions are as follows:
• Relative humidity range is 20 percent to 80 percent noncondensing.
• Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the
LSISAS3108 processor above the maximum ambient temperature.
• Temperature range: 10°C to +55°C
The parameters for the nonoperating (such as storage and transit) environment for these
controllers are as follows:
• Relative humidity range is 5 percent to 90 percent noncondensing.
• Temperature range: –40°C to +70°C
Power Supply Requirements for the Intel
®
RAID Controller RS3SC008
All power is supplied to the Intel
®
RAID Controller RS3SC008 through the PCIe 3.3V
rails and the 12V rail. On-board switching regulator circuitry operating from the 3.3V
rails and the 12V rail provides the necessary voltages. The following states determine the
typical current consumption of the controller:
• State 1: While sitting idle at the DOS prompt
• State 2: During a drive stress test
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± 9
percent (from PCI edge connector only). The following table lists the power supply for the
RAID controllers for these two states at the different voltages.
PCI Edge Connector State 1 State 2
3.3V supply 727mA 1030mA
+12V supply 1050mA 1410mA
3.3V auxiliary supply 10mA 10mA
Total Power 15.212W 20.574W
