This produces the following power consumption:
Slot #1 Power Consumed =
975
+
0
+
2 x 100
=
1175
Slot #2 Power Consumed =
1350
+
0
+
2 x 100
=
1550
Slot #3 Power Consumed =
475
+
0
+
4 x 100
=
875
Slot #4 Power Consumed =
700
+
25 x 100
+
2 x 100
=
3400
Slot #5 Power Consumed =
780
+
0
+
4 x 100
=
1180
Slot #6 Power Consumed =
1000
+
2 x 200
+
4 x 100
=
1800
Totals for each bank can then be calculated as follows:
Slot 1
Slot 2
Slot 3
Total
Bank #1 Power Consumed =
1175
+
1550
+ 875
=
3600
Slot 4
Slot 5
Slot 6
Total
Bank #2 Power Consumed =
3400
+
1180
+ 1800
=
6380
Result: Because each bank has not exceeded maximum power, this is OK.
