The PowerEdge T320 supports up to two PSUs with 1+1 redundancy, auto-sensing and
auto-switching capability. The T320 also supports PSU 2+0 configurations for configurations that
exceed the output of a single PSU; in this case, 1+1 redundancy is not supported. Use the Dell
Energy Smart Solution Advisor at Dell.com/ESSA to help you configure your system optimal power
performance. Dell PSUs have achieved Platinum efficiency levels as shown in Table 17.

Thermal and acoustics
Optimized thermal management makes the PowerEdge T320 cool and quiet. Benefiting from smart
cooling fan speed control, the T320 can keep both high performance and good acoustics across a
wide range of ambient temperatures from 10°C to 35°C (50°F to 95°F) and to extended ambient
temperature ranges (see Table 27). Operating environments for the T320 can vary from the data
center to general-use spaces. In a typical configuration, the T320 is suitable for an open office
environment.
