Question about 3d printer electronics, power supply

Hi
I am working on a 3d printer and I was wondering if the power supply I bought will power it?
I am using a MK2B12/24V Heat Bed, a Ramps 1.4 board from ultimachine, arduino mega, 4 nema17 stepper motors, and a Bowden All Metal hotend from Folger Technologies.
Here is a link to the hotend.

It is a Reprap Rostock delta 3d printer.
I bought a 12v 20amp power supply.
Here is a link to the power supply

I was just making sure everything will work for the printer before I hook it up.
Thanks
Tanner
