Power and Signal Distribution
Table 7-3 lists the specifications for the 365-watt power supply used in the MT and CMT form
factors
NOTES:
Total continuous output power should not exceed 365 watts. Maximum surge power should not exceed 385 watts.. Maximum
combined power of +5 and +3.3 VDC is 160 watts.
[1] Minimum loading requirements must be met at all times to ensure normal operation and specification compliance.
[2] Maximum surge duration for +12Vcpu is 1 second with 12-volt tolerance +/- 10%.
