Power Budget
Power Budgeting
NOTE: The PCI tray provides power for option cards from both a +5 Vdc source and a +3.3 Vdc
source. Cards may use either or both power sources, up to 25W per slot. However, the
+3.3 V dc source is limited to 39.8 W combined for slots 1 and 2, and 39.8 W combined
for slots 3 and 4. For example, if the card in slot 1 draws 25 W at +3.3 V dc, only 14.8
W at +3.3 V dc is available to a card in slot 2. The limits of + 5 Vdc is 25 W per slot.
