This SEASONIC is far SUPERIOR to the ones you linked.

 
But can I use the EVGA (http://www.wootware.co.za/evga-110-b1-0750-vr-supernova-750-b1-750w-80-plus-bronze-certified-semi-modular-desktop-power-supply.html) without any trouble on my system wih a Polaris R9 490 8 GB
 


That is a nice Seasonic - but do you really need 850 Watts? They make lower output models of the M12ii.

I personally own the Seasonic S12ii 520W - not only are they one of the best manufacturers of Power Supplies, they have been making power supplies for longer then most of the users on tomshardware have been alive.
