Technical Product Specification

350W Power Subsystem Intel® Server System R1304BTSSFAN/ R1304BTLSFAN/ R1304BTLSHBN TPS
4. 350W Power Subsystem
The power subsystem of the server systems consists of a single, non-redundant 350-W power
supply with five outputs: 3.3 V, 5 V, 12 V, -12 V, and 5 VSB. The form factor fits into a 1U
system and provides a wire harness output to the system. An IEC connector is provided on the
external face for AC input to the power supply. The power supply provides one non-redundant
40 mm fan for self-cooling. The power supply fans also provide additional airflow for parts of the
system.
The power supply operates within the following voltage ranges and ratings.

Notes:
1. Maximum input current at low input voltage range shall be measured at 90VAC, at maximum load.
2. Maximum input current at high input voltage range shall be measured at 180VAC, at maximum load.
The power supply must operate within all specified limits over the input voltage ranges shown in
the table. Harmonic distortion of up to 10% Total Harmonic Distortion (THD) must not cause the
power supply to go out of specified limits.
