The SOtM tX-USBexp is a USB 3.0 card designed for a hi-end audio USB connection.  It includes an external or internal power input, a USB port power switch, and a USB 3.0 port.


The HDPlex 200 W Linear Power Supply is a DC-DC power supply that produces a much cleaner signal than can be achieved with standard AC-DC power supplies.  They are useful for audio computers due to their low ripple noise and no high frequency noises.  Five power outputs are available to power a computer as well as other internal or external devices.  The motherboard and any other internal devices such as Solid State Drives will be powered with separate cables for electrical isolation.
