Table 6. Power Dissipation Equations:
Power Dissipation (kVA) Equation
Power Dissipation (kVA) =
(Number of CPUs x 0.191) + (Number of PCI Units x 0.886) + 2.818
Power Dissipation (kVA) =
(Number of CPUs x 0.191) + (Number of PCI Units x 0.886)+ 1.409
Power Dissipation (kVA) =
(Number of CPUs x 0.22) + (Number of PCI Units x 0.886) + 1.71
