How To Find Power Supply Hardware Information on Ubuntu Command-Line

Ubuntu 21

In this article, we will explore different methods to find power supply hardware information using the Ubuntu command-line. This can be useful for troubleshooting, system monitoring, or even when planning hardware upgrades.

Quick Answer

To find power supply hardware information on Ubuntu command-line, you can use the dmidecode command with the appropriate type option, such as -t 39 for battery information. You can also try using the sensors command to display sensor information, although it may not provide specific power supply details. Another option is to use ipmitool if your system supports IPMI. If none of these methods work, you can check the physical label on the power supply unit or search online using the make and model of your computer.

Using dmidecode

The first method involves using the dmidecode command. This command is a tool for dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. The -t option is used to specify the type of information you want to retrieve. For instance, to get information about the battery, you can use the type 39 as follows:

sudo dmidecode -t 39

This command should provide information about the battery on your system. However, it may not give you the details about the power supply. If it doesn’t show the desired information, you can try other methods.

Using sensors

The sensors command is another useful tool that displays sensor information, including power consumption, fan speed, and temperature. However, this may not provide specific details about the power supply. To use it, simply type:

sensors

Using ipmitool

The ipmitool is used for managing IPMI-enabled devices, including power supply units. However, it requires IPMI support on your system and may not be available on all machines. To use it, type:

ipmitool

If none of the above methods provide the information you need, there might not be a direct command-line tool available to retrieve the power supply hardware information. In such cases, you can try the following alternatives:

Checking the physical label

Look for the safety label on your power supply unit. It should provide details about the output voltage, wattage, and other specifications. If you don’t have physical access to the PC, you can ask someone on-site to provide you with a picture of the power supply label.

Searching online

If you know the make and model of your computer, you can search for the power supply specifications online. Many manufacturers provide detailed information about their products on their websites.

Remember, adding a second GPU may require a power supply with sufficient wattage and the necessary power connectors. It’s important to ensure that your power supply can handle the additional load before installing the GPU.

In conclusion, while there isn’t a straightforward way to find power supply information directly from the Ubuntu command-line, there are several methods you can use to gather this information. Whether you’re troubleshooting, monitoring your system, or planning a hardware upgrade, these methods should help you find the information you need.

What is the purpose of finding power supply hardware information on Ubuntu command-line?

Finding power supply hardware information on Ubuntu command-line can be useful for troubleshooting issues related to power supply, monitoring power consumption, and planning hardware upgrades.

What is the `dmidecode` command used for?

The dmidecode command is used to retrieve information from a computer’s DMI (Desktop Management Interface) table. It can provide details about various hardware components, including the battery and power supply.

How can I use `dmidecode` to find power supply information?

You can use the dmidecode command with the -t option followed by the type number for power supply, which is 39. The command would look like this: sudo dmidecode -t 39.

What can I expect to find with the `sensors` command?

The sensors command displays sensor information, including power consumption, fan speed, and temperature. However, it may not provide specific details about the power supply.

How can I use `ipmitool` to find power supply information?

ipmitool is a tool for managing IPMI-enabled devices, including power supply units. To use it, simply type ipmitool in the command-line. However, please note that it requires IPMI support on your system and may not be available on all machines.

What should I do if none of the command-line methods work?

If the command-line methods do not provide the desired information, you can try checking the physical label on the power supply unit or searching online using the make and model of your computer. Manufacturers often provide detailed information about their products on their websites.

Why is it important to ensure that the power supply can handle the additional load before installing a second GPU?

Adding a second GPU to your system can increase power consumption significantly. It’s crucial to ensure that your power supply has sufficient wattage and the necessary power connectors to handle the additional load. Insufficient power supply can lead to system instability or even damage to the components.
