four wires. USB cables have a standard of four wires inside them. These have different colors that indicate what their uses are. The USB wire color code dictates the purpose of a specific wire. Usually, there are two wires for … Continue reading →

300 watts is enough if it’s a single rail PSU and the system has an overall low power design aside from the components mentioned. Most people never upgrade their computer in a way that significantly increases the power requirements, so … Continue reading →

around 2 amps. So you need to make sure the amperage for the USB sockets are rated at around 2 amps. Most modern devices use ‘intelligent charging’ circuitry which means they will take the maximum amperage they can for optimum … Continue reading →

If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may … Continue reading →
