I'm New To PSUs Can You Help Me Out?

PSU - http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028


So my first question is will any PSU work with any system if it is enough watts? (I checked the dimmensions they match up with my current PSU)

Also does this one come with 2 PCI 6 Pin Cables?

Yes, and yes. The one in the link you posted is cheaper on Amazon btw.
