Power Consumption Specification
The power consumption values below show the voltage and power specifications of the TQMx50UC.
The values were measured with two power supplies; one for the TQMx50UC and the other one for the MB-COME6-1 COM
Express™ carrier board.
The power consumption of each TQMx50UC was measured under Windows
®
7, 64-bit.
All measurements were done at a temperature of +25 °C.
The power consumption of the TQMx50UC depends on the application, the mode of operation and the operating system.
The power consumption was measured under the following test modes:
•
Windows
®
7, 64-bit, idle state:
Desktop idle state, Ethernet port is disconnected.
•
Windows
®
7, 64-bit, maximum workload (cTDP down mode enabled)
These values show the maximum cTDP down power consumption using the Intel
®
stress test tool to stress the
processor and graphic engine. Ethernet port is connected (1,000 Mbps Speed).
•
Windows
®
7, 64-bit, maximum workload:
These values show the maximum worst case power consumption using the Intel
®
stress test tool to stress the processor
and graphic engine. Ethernet port is connected (1,000 Mbps Speed).
•
Suspend mode:
The system is in S5/S4 state, Ethernet port is disconnected.
•
Green ECO-Off state:
The system is in Green ECO-Off state, all DC/DC power supplies on the TQMx50UC are switched off.
The following table shows the power consumption with different processor configurations.

Note: Power requirement
The power supplies on the carrier board for the TQMx50UC must be designed with enough reserve.
The carrier board should be able to provide at least twice the maximum workload power of the
TQMx50UC. The TQMx50UC supports several low-power states. The power supply of the carrier board
has to be stable even with no load.
