I have a high power (700ma+) USB device I wish to use on a single front-panel USB port.
The USB specification in Wikipedia states:
The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices. A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0.
When using the device in a normal USB port the voltage drops to 4.7~ Volts, which is dangerously low for my device.
My front-panel dual USB ports are connected to a USB header on the motherboard which supplies the power and the data transmission lines.
My PSU is a 750w that can supply up to 25A on the 5V rail.
Is it possible to remove the power lines (Vcc and GND) from the front panel and then replace them with the 5V and GND from the PSU?
Will this procedure be safe for my PC, power supply and device being powered?
