7.2.2 MT Power Supply
The MT form factor comes standard with a 300-watt, passive-PFC power supply unit with the
specifications and cabling as indicated in the following table and figure.
NOTES:
Total continuous output power should not exceed 300 watts. Maximum surge power (<10 seconds) should not exceed 320 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%.
NOTES:
All + and - values are VDC.
RTN = Return (signal ground)
GND = Power ground
RS = Remote sense
POK = Power ok (power good)
[1] This row represents pins 13–24 of connector P1.
