I have not researched anything about PS's for a while now... so most of my knowledge about rails and capacities and all of that has gone completely out the window. Can anyone suggest a PSU that would be powerful enough to handle that load (below), stable, and preferibly in the 'under $50' range? Thank you 
I picked one out from a brief look at NE.com - would this do the trick? Or if not... could you please suggest something that would be able to? Thank you
