Power Supply and Cooling
The workstation power supply has five outputs:
•
+3.3V — PCI, AGP, Granite Bay MCH, ICH4, Audio, SCSI, on-board logic and input
for on-board voltage regulators
•
+5V — disk drives, PCI, AGP, and on-board logic
•
+12V — fans, PCI, AGP, disk drives, and input to on-board voltage regulators
(including the one that supplies power to the processor)
•
-12V — used by PCI
•
5VSB — for “sleep” circuitry
Total continuous output power not to exceed 320W.
Combination of 5V and 3.3V power not to exceed 250W.
