What power supply do i need?

[Lscheres]

Ok so i bought these high speed 120mm fan that are really nice and stuff but i failed to notice that they are 48v. What type of power supply do i need to power these. they arnt for use in a computer im just using them to vent something because they have a 200 cfm rate. i have a fan controller but im pretty sure it wont work because its meant for 12v fans. If anyone could shed some light on this for me i would be very appreciated. i need these fans to work very soon, if it helps these are the fans NEW Sunon 120mm Ball Bearing Rotary Cooling Fan 4000RPM - eBay (item 120446634124 end time Apr-06-10 13:48:11 PDT)

Perhaps it's a really new or old type of pin? I've never come across it before. I can't think of anything it could fit into, just by looking at it. Half of a reverse 4-pin molex, at a stretch?

Wikipedia doesn't know of it, at least:
