HELP! Dell XPS 8100 Upgrade Hardware

Hello all, 

Have some questions concerning upgrading my 8100,

i am trying to get it run as a gaming computer to run things such as the most recent total war games, 

At the moment i have no graphics card (last one broke)  and am in need of a new one....

Have  looked on the web concerning this and have found that people have used the Radeon r9 270x as an upgrade. 

Which obviously means upgrading the original 350 watt PSU to support it, people have  recommended the Seasonic S12II 520  to others.....

So my question is can i just add in the radeon r9 270x and the Seasonic S12II 520 without any issues? 

Please let me know where you think i should go with this!

S12II-520 is too small.   EVGA 700B1 or NEX 750B1 will work fine.

That series seasonics only have 130W max on the 3.3v/5v Rails.

This seasonic

SeaSonic M12II 750 SS-750AM2 750W 

 is fine

Dell Power supplies have combined 142 to 150W on the 3.3v/5v rails and at least 15W on the 5VSB Rail.  This is the case all the way down to 305W units.  Power supplies are not single 12v units with a single spec of watts.  The other rails maximums count. on the 875W unit this spec goes UP to 225W on the 3.3v/5v rail.



CORSAIR TX650 works fine but CX650 does not for the same reasons.
