Technical Product Specification

Intel® Server System R1304BTSSFAN/ R1304BTLSFAN/ R1304BTLSHBN TPS 350W Power Subsystem
4.4
Marking and Identification
The power supply module marking supports the following requirements: safety agency
requirements, government requirements (if required, for example, point of manufacturing),
power supply vendor requirements, and Intel manufacturing and field support requirements.
4.5
Efficiency
The power supply should have a recommended efficiency of 85% at maximum load and over
the specified AC voltage.
4.6
AC Input Voltage
The power supply must operate within all specified limits over the following input voltage ranges,
shown in the following table.

Notes:
1. Maximum input current at low input voltage range should be measured at 90 VAC at maximum load.
2. Maximum input current at high input voltage range should be measured at 180 VAC at maximum load.

Output Power/Currents
The following table defines two power and current ratings for this 350W power supply. The
combined output power of all outputs should not exceed the rated output power. The power
supply must meet both static and dynamic voltage regulation requirements for the minimum
loading conditions.

2. The total output for this PSU is 350W.
3. The total output of +3.3V and +5V will not exceed 100W.
4.8
Protection Circuits
Protection circuits inside the power supply should cause only the power supply’s main outputs
to shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle
