USB Power Delivery specification enables up to 100W

Posted on Friday, July 20 2012 @ 12:05:13 CEST by

The USB Implementers Forum has finalized the USB Power Delivery Specification, enabling manufacturers to create standards-compliant systems providing up to 100W of power to client devices.
The USB 3.0 Promoter Group - a conglomeration of companies including Hewlett-Packard, Intel, Microsoft, Renesas, ST-Ericsson and Texas Instruments - is pushing the USB Power Delivery Specification as an upgrade to its 2008 USB 3.0 specification. While performance is unmodified over USB 3.0, power availability gets a significant boost with client devices able to demand up to 100W from host systems.

With so much power on demand, the Group sees a great deal of promise for bus-powered devices: as well as the current crop of bus-powered external hard drives and optical drives, which typically need two USB 2.0 connections to run, the new specification could potentially lead to single-cable USB-powered RAID boxes, large-format displays, surround-sound speaker systems, and even printers.
