Appropriate power supply for 12V 150W DC fan

Hello all,

I'm attempting to use my arduino plus an SSR or relay to control on/off state of this fan/heater:

Anyone know where I could find an appropriate power supply? I don't have too much knowledge on this subject so any guidance would be appreciated. If at all possible, I'd love to find a way to power this from a wall socket, as I'll be building potentially many of these boxes, and don't want to buy that many separate power supplies. If I could feed several of these off one power supply it would be super helpful.

Thanks for the guidance!

I was thinking a 250-300w computer power supply would be appropriate.

Is that something where I could run several fans from one power supply or would I need a power supply per arduino?

Edit: Also are there any resources that help with learning how to hook up pins like that to a simple circuit?

Required is a 12V power supply, with about 15A for each heater.

Look up power switching with relays, SSR and MOSFET. There you'll find circuit descriptions and software hints.
