This is a brand new PS I bought for my Big Disk Extreme thinking it might fix an issue with it, but I was wrong.
If anybody has an interest, just make a reasonable offer, I can ship to Canada/USA.

Specs from the LaCie website:

Power:
DC Output: 12V(3A) / 5V (4,2A)
AC Input: 110V / 220V

4-pin connector
