- Connect the USB device to your computer.
- Right-click on the «Start» button and select «Device Manager» from the context menu.
- In the Device Manager window, expand the «Universal Serial Bus controllers» section.
- Locate the USB device you wish to check, right-click on it, and select «Properties».
- In the Properties window, navigate to the «Power» tab.
- Under the «Power» tab, you will find the information regarding the power consumption of the USB device. This includes details such as power required, power available, and power status.
By following these steps, you can easily check the power consumption of any USB device connected to your Windows 10 computer. This information can help you ensure that you do not exceed the power limit of your USB ports and avoid any potential issues or hardware failures.
Frequently Asked Questions:
Q: Why is it important to check USB power consumption?
A: It is essential to monitor USB power consumption to ensure that your devices are operating within safe limits. Exceeding the power capability of your USB ports can lead to various problems such as reduced performance, device malfunctions, or even damage to your computer’s hardware.
Q: Can I check the power consumption of all connected USB devices simultaneously?
A: No, you can only check the power consumption of individual USB devices. The power consumption of each device is specific to its design and hardware requirements. Therefore, it is necessary to check the power consumption of each device separately.
Q: Are there any software tools available to monitor USB power consumption?
A: While Windows 10 does not provide a built-in tool to monitor USB power consumption, there are several third-party software applications available that can help you track power usage. These tools provide more detailed information and can be useful if you require in-depth analysis of power consumption on your computer.
Q: What should I do if a USB device exceeds the power limit?
A: If a USB device exceeds the power limit of your computer’s USB ports, you may experience various issues. To resolve this, you can try connecting the device to a powered USB hub, which can provide additional power. Alternatively, you may need to consider using a different device or upgrading your computer’s hardware to support higher power requirements.
By following these steps and keeping a close eye on the power consumption of your USB devices, you can ensure the optimal performance and longevity of your computer system.

The Universal Serial Bus is a very useful PC interface. The bus concept allows for almost endless devices to be connected to a PC, where the older serial port and parallel port interfaces were very limited. USB power usage is also better than on serial and parallel ports, allowing devices to draw more power.
The bus concept also means that there are shared resources on the USB interface. The data link is shared, but the USB protocol ensures this resource is used efficiently and error-free. The power consumption on a USB port is also shared, which means that any USB device should not exceed a certain power usage limit.
If you want to know how much power a USB device is using, follow these steps:
(the example is based on Vista, but can be used for Windows XP and newer Windows versions as well)
- In the Windows Start menu, select Run.
- In the Run dialog box, type
devmgmt.mscand press Enter or click OK. - In the Device Manager window, open the branch called Universal Serial Bus Controllers.
- Now right-click a USB Root Hub, and in the popup menu select Properties.
- In the USB Root Hub Properties dialog box, select the Power tab.
- Under the Hub Information, you can read the power available to the hub, and in the Attached devices list you can see which USB devices are connected to the hub and how much power they require.
- Repeat steps 5 and 6 to check the power for all USB Root Hubs.
While going through the list, check if any of the total power requirements of the attached USB devices exceeds the power capabilities of the hub. If that is the case, you can try a number of things.
The simplest solution is to plug one of the USB devices into a different USB port if available. If it is a single device causing the overload, this won’t work of course.
Another option is to use an external USB hub. Use a USB hub with its own power supply, so the PC’s USB port is not overloaded anymore. Do check the specifications of the USB hub, so it will meet the USB power requirements of your devices.
If it is a single USB device causing the problem, the USB device probably also has its own power supply. External USB hard disks often have the possibility to use the USB port for power or to use an external, separate power supply. Since hard disks can take considerable power, it is better to always use the external power supply.
If you want to read more about the USB interface, check the USB specification documents.
Update: Apart from relying on what is reported within the Windows Device Manager, it is also possible to use an external USB power meter. These devices simply plug in between the USB device and the USB port and indicate the actual power usage by the device.

Так как большинство подключаемых по USB устройств являются пассивными, то есть получающими питание от компьютера, иногда бывает полезно знать, каким объемом энергии может обеспечить их USB-порт компьютера. Для определения выдаваемой мощности лучше всего использовать вольтметр, но можно воспользоваться и программными средствами. Сторонние утилиты в этом плане более удобны и информативны.
В крайнем случае для определения доступной мощности вы можете воспользоваться штатными средствами Windows.
Откройте диспетчер устройств, разверните пункт «Контроллеры USB» и дважды кликните по устройству, сведения о котором хотите получить.
Портам соответствуют устройства «Корневой USB-концентратор» или «Универсальный USB-концентратор». В открывшемся окошке свойств переключитесь на вкладку «Питание». В сведениях о концентраторе будет указана доступная для него мощность, также вам будут доступны сведения о подключенных к концентратору устройств. Из данного примера видно, что к порту можно подключить устройство, потребляющее силу тока 500 mA. Зная же выдаваемое напряжение (для периферии это 5 B), легко вычислить мощность, умножив силу тока на напряжение.
Чтобы получить информацию о подключенном устройства, дважды кликните по нему в окошке свойств концентратора. В результате откроется еще одно окошко свойств, в котором будет указана требуемая подключенным устройством мощность. Для получения дополнительных сведений о текущем состоянии устройства в свою очередь открываем его свойства и переключаемся на вкладку «Сведения». Здесь в выпадающем меню нужно выбрать пункт «Сведения о питании».
Обратите внимание на текущее состояние электропитания.
- D0 — устройство подключено и поддерживает функциональную готовность работы в системе.
- D1 — устройство находится в состоянии ожидания включения.
- D2 — работа устройства приостановлена.
- D3 — устройство находится в состоянии отключения.
Если же вам нужно узнать потребляемую подключённым устройством мощность, воспользуйтесь утилитой USBDeview от разработчика Nirsoft.
www.nirsoft.net/utils/usb_devices_view.html
Запущенная утилита выводит список активных и неактивных устройств, кликните дважды по интересующему вас устройству мышкой.
В открывшемся окне свойств посмотрите значение в поле «Мощность (ток)», в нём будет указан потребляемый устройством ток в миллиамперах.
Другой вопрос, насколько полученные данные отвечают действительности. Поэтому для определения потребляемой мощности всё же лучше использовать приборы.
