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%.
