Can You Still Charge an MP3 Player When Your Computer Is in Sleep?

You can charge your MP3 player even when you don't want to use your computer for any other reason. Most computers allow for power to be sent via USB while they are asleep, and some even allow it when they are turned off. If your computer doesn't supply USB power while in sleep mode, you will have to change your computer's power settings

Can You Overcharge Electronics?

Proper battery care can significantly increase the longevity of an electronic device and although measures have been taken to ensure that overcharging is unlikely, many electronic devices can still suffer from overheated batteries. Overcharging a device can also increase energy costs, with British energy provider E.ON reporting that consumers waste a significant amount of money by leaving devices plugged in for longer than necessary.

Are Power Generators Safe for Computers?

Power generators are standalone electrical devices that provide electricity during a power outage or when you cannot access electricity. The devices contain gasoline-powered engines and 110V electrical outlets, as well as 220V outlets on some models. It is safe to power computers, including desktop and laptop models, televisions and other electronics using a power generator, but you need to connect a surge protector between the generator and your computer or other electronic device.

Is It Possible to Test a PC PSU Without the Motherboard?

Testing a computer power supply – or an individual computer component – usually requires plugging in a motherboard since the PSU won't run without the motherboard connected. Using a paperclip, however, you can trick the power supply into running even without a motherboard. This method will allow you to start the PSU and any connected components to make sure they power up. However, to truly test functionality, you will need to put the entire computer together.

The Wire Color Standards for Computer Power Supplies

Power supply units are critical components of your computer, contributing to the stability and reliability of your computer's performance. Most personal computers require advance technology extended PSUs. PSUs use a primary circuit to feed a transformer converting the 60Hertz alternating current from a standard power source to a higher frequency. When you choose an ATX PSU for your computer, select one that adheres to industry wire color standards and consider the printed circuit board input and output voltage capacity.
