Intel Desktop Board D865PERL Technical Product Specification 2.11 Electrical Considerations 2.11.1 DC Loading Table 43 lists the DC loading characteristics of the board. Table 43. DC Loading Characteristics Mode Minimum loading Maximum loading DC Power 196 W 330 W +3.3 V 6 A 12 A +5 V 11 A 15 A DC Current at: +12 V -12 V 9 A 0.03 A 16 A 0.10 A +5 VSB 0.80 A 1.60 A 2.11.2 Add-in Board Considerations The Desktop Board D865PERL is designed to provide 2 A (average) of +5 V current for each addin board. The total +5 V current draw for add-in boards for a fully loaded Desktop Board D865PERL (all five expansion slots and the AGP slot filled) must not exceed 12 A. 2.11.3 Fan Connector Current Capability CAUTION The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation. Table 44 lists the current capability of the fan connectors on the Desktop Board D865PERL. Table 44. Fan Connector Current Capability Fan Connector Processor fan Front chassis fan Rear chassis fan Voltage regulator fan Maximum Available Current 1600 mA 600 mA 600 mA 1000 mA 78
