I am happy to see you are not expecting to pay $60.00 for a PSU that will run your system WELL
look for the Antec Trio Rail SP-3 650 watt PSU they are selling for around $110.00 mark
the Antec trio is FAR better than that Coolmax and a few bucks cheaper
the antec is rated to run at 50C operating environment and is 85% efficient
the coolmax doesnt state its temp rating and no efficiency rating these are signs of poor build
then compare the customer reviews between the two units, wont take you much looking to get you into a better unit!
enjoy, that antec is awesome quiet too and I know it has your needed 8pin eps connector!
