This is just standard USB front, with USB 3.0 cable which goes to motherboard. It will give you only what specification says. Wikipedia says that about USB 3.0 power specs:

Power and charging
As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 W), almost twice USB 2.0's 500 mA.[10]:section 9.2.5.1 Power Budgeting
USB 3.0 ports may also implement other USB specifications for increased power, including the USB Battery Charging Specification for up to 1.5 A or 7.5 W, or, in the case of USB 3.1, the USB Power Delivery specification for charging the host device up to 100 W.[12]

I tried 2 Moolanders on my USB 3.0 front from my Fractal R5 case. They can work just fine at 756MHz. I wouldn't try anything above that, I don't want to fry my motherboard
