400 W DC-ATX Internal Adapter


The HDPlex 400 W Linear Power Supply is a DC-DC power supply that produces a much cleaner signal than can be achieved with a standard AC-DC power supply.  They are useful for audio computers due to their low ripple noise and no high frequency noises.  Six 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.

A 400 W internal DC-ATX adapter will be installed in the computer to power the motherboard and processor.
