7 Power Supplies, Power
Distribution Board, and Fans
This chapter provides information for the deskside and desktop power supplies and fans. The power
distribution board information is also included here for systems using the internal RAID section.
Deskside Power Supply (MPWS131)
The TDZ-410, TDZ-610, InterServe 605, and InterServe 605UW systems use the MPWS131 power
supply, which has a maximum output of 539 watts.
NOTE
If the system has internal RAID section, a power distribution board is also installed. Refer to "Power
Distribution Board (MPCBD13)" later in this section for more information.
The power supply is switchable (autoranging) between 90-132 VAC or 180-264 VAC, depending on
the location. The input frequency is 47-63 Hz, single phase. At full load, nominal AC line, nominal
power factor of 0.6, and temperature of 25 C, the power supply has a minimum efficiency of 65
percent.
DC Output Specifications
The following table details the power supply DC output specifications.

Notes:
1.
The 539 W power supply meets or exceeds the specifications in the above table. For the noted
specifications, the Maximum values describe the smallest acceptable maximum load, and the
Minimum values describe the largest acceptable minimum load.
2.
These outputs are measured at the connector of a loaded cable.
3.
The +3.3 V and +5.1 V outputs do not draw more than 400 watts combined.
