This produces the following power consumption:
Slot 1 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Slot 2 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Slot 3 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Slot 4 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Slot 5 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Slot 6 power consumed =
700
+
60 x 100
+
4 x 100
=
7100
Totals for each bank are calculated:
Slot 1
Slot 2
Slot 3
Total
Bank #1 power consumed =
7100
+
7100
+ 7100
=
21300
Slot 4
Slot 5
Slot 6
Total
Bank #2 power consumed =
7100
+
7100
+ 7100
=
21300
NOTE
Since each bank exceeded the maximum power, some operations will not be performed and an error
will be generated.
