Here's the info on that: eSATAp stands for powered eSATA. It is also known as Power over eSATA, eSATA USB Hybrid Port (EUHP), or eSATA/USB Combo. An eSATAp port combines the 4 pins of the USB 2.0 (or earlier) port, the 7 pins of the eSATA port, and optionally two 12-volt power pins.[28] Both SATA traffic and device power are integrated in a single cable, as is the case with USB but not eSATA. Power at 5 volts is provided through two USB pins; power at 12 Volts may optionally be provided. Typically desktop, but not notebook, computers provide 12 volt power, so can power devices requiring this voltage, typically 3.5" disk and CD/DVD drives, in addition to 5 volt devices such as 2.5" drives.
Both USB and eSATA devices can be used with an eSATAp port, when plugged in with a USB or eSATA cable, respectively. An eSATA device cannot be powered via an eSATAp cable, but cables are available which make available both SATA or eSATA and power connectors from an eSATAp port. An eSATAp connector can be built into a computer with internal SATA and USB, by fitting a bracket with connections for internal SATA, USB, and power connectors and an externally accessible eSATAp port. Although eSATAp connectors have been built into several devices, manufacturers do not refer to an official standard. Information is from Wikipedia at: http://en.wikipedia.org/wiki/Serial_ATA#eSATAp So... My understanding is that with a compatible eSATA connector on the external device it should power the External unit without the use of an external power supply cable. Also, you can hook up normal eSATA to this as well. I've done it many times :) Regards, Tim Lider Sr. Data Recovery Specialist Advanced Data Solutions, LLC http://www.adv-data.com > -----Original Message----- > From: [email protected] [mailto:hardware- > [email protected]] On Behalf Of Winterlight > Sent: Monday, April 09, 2012 1:36 PM > To: [email protected] > Subject: Re: [H] External power eSTATa > > > I don't know.
