Dell PowerEdge R320 Technical Guide

28 PowerEdge R320 Technical Guide
Figure 7 shows a 350W power supply unit extended from the R320 chassis.
Figure 7. 350W power supply unit
The PowerEdge R320 supports up to two AC with 1+1 redundancy, auto-sensing and
auto-switching capability.
To support Intel turbo boost feature (default enabled in BIOS), system with 95W processors (8-core
or 6-core) and 350W cabled PSU may not be sufficient to support feature rich configurations. For
feature rich configurations, using a 350W or 550W hot-plug PSU is recommended in addition to
verifying energy efficiency configurations using the Dell Energy Smart Solution Advisor at
Dell.com/ESSA.
Dell PSUs have achieved Platinum efficiency levels as shown in Table 17.

Thermal and acoustics
Optimized thermal management makes the PowerEdge R320 cool and quiet. Benefiting from smart
cooling fan speed control, the R320 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 26). Operating environments for the R320 can vary from the data
center to general-use spaces. In a typical configuration, the R320 is suitable for an open office
environment.
Thermal design
The thermal design of the PowerEdge R320 reflects the following:
 Multiple sensors are monitored for thermal feedback control: The PowerEdge R320
dynamically controls system cooling fan speed based on responses from component
temperature sensors, including processors, HDDs, DIMMs, storage cards and the inlet ambient
