Does anyone know what the power consumption is? I want to daisy chain three on Firewire, and need to make sure there's enough power in the Firewire in

I'm able to daisy chain a second firewire drive (not another My Passport) to my Macbook Pro, and both drives work fine.

I have no idea what the power consumption is, but I've daisy chained 2 units before with FireWire 800 and it's been fine, works great.

I have had a 500gb & a 1tb,(both my passports), chained on a macbook pro newest model, with no problems at all.

Mine contains WD5000AAKS with jumper PM2 (PUIS). With USB power meter: 4 watt to spin-up, between two and three watt activity, and one watt in low-power state (spun-down standby). I do not know how it compares to 1394 power usage.

I am sure it must be. Actually I use Firewire so the question does not arise.

that's what I am doing - here's what i am finding...the control item (using a kill-a-watt) is still drawing .005 amps when everything else is off...i know this is practically negligible and in the scheme of things it's not really gonna matter money wise, just led me to the question that if the most least power consumption device (i.e. -0-) was the control item there would be absolutely no draw whatsoever. Thank you for your replies and if I am completely off base, please let me know

It is bus powered using the FireWire 800 to Thunderbolt. It's very fast and flawless. I use it with my 2012 Mac Mini. The company was bought late last year so I would buy one now !

In addition to the great comments below, this kind of partitioned power supply is a great improvement over daisy chaining, both in terms of cumulative signal noise and in the performance of your pedals individually. That said, I'd recommend getting the pedal power but also staying open to replacing other components that might still cause your signal to be noisy after you've changed your power supply. Cheers, and best of luck!

Yes! This PCIe Card requires the desktop computer's power supply plug into it. In order to make the Firewire connections work.

It does have firewire 800 so that was good. I have not upgraded to Lion so I cannot answer if it works with Lion, but you could contact WD and they would tell you.

I have found the drive to be reliable over many months of porting between multiple computers. I have no power issues using the Firewire 800 port. I have not experienced any loosening of the port and have used it extensively interchanging between multiple machines (iMacs) as noted above.

The only issue you may run into is if you want to stay in peak efficiency, which is usually around 50% give or take. Also note that running multiple(3+ probably) hard drives adds up on the wattage used too.

the PoE feature doesn't add current draw (power consumption) unless you're actually using it...unless a PoE device is connected. There is no benefit to disabling the feature.

Hi there, I got one couple of months ago and i am quite satisfied. To be honest i did not attempted to use it without FireWire cable but the point is this device is provided by a power supplier in the box which means it can work as a stand alone device without computer. I guess there should be no problem for what you wanna do. All the best

You need to install a FireWire Network Card (e.g. IEEE-1394a FireWire Controller Card).

Working on my mac mini perfectly. USB3.0 and OSX Mavericks. I have not used the firewire port but I assume it will work well.

9, if i remember, but take a look to this page:http://en.wikipedia.org/wiki/Firewire

Yes, at least mine were using Firewire. This one also has Firewire and a USB 3.0 port, while earlier models do not. That worked out great for connecting USB 3.0 to a new 5k iMac, which is faster than FW anyway; but my older ones cannot as the 5k iMac has no Firewire port.

I think minimum is 500 watts, double that for xfire! But then it also depends on how much hardware is in your comp to begin with, like more then 2 HDD, 9 case fans etc.....

Try and use - plug into - Firewire as it is faster than USB2.USB Speed = 400 Mb/s Firewire 800 = 800Mb/s
