Hey guys I am after a power supply for a Drobo 5N , I am guessing I can use a standard power supply , Appears to be a round 4 pin plug.

There site lists it as this

EDAC Model: WA1101E-120, Part Number: EA11001E(52), AC Input 100-240V-2.5A100W

Thought I would ask here before I go on a search or perhaps you could suggest where I could pick one up from.

Edit :  I might have been wrong and its not a 4 pin plug but a normal prong plug.
