The CPU has a draw of 125W under full load (not overclocked), the graphics I am unsure of but I imagine something like 150W (again not overclocked). Throw in another 30W for the motherboard/RAM and you have a rough draw of 300W under full load on the 12v rail.
Overclock the components and you can add another 50W or so. So ~350W draw when overclocked.
PSU are typically most efficient at 50-70% load, so a 550-600W PSU is good for this system.
That Corsair CX600 is a good unit and a steal right now, would jump on it.
Alright so I will go with that PSU, About my video card I have a VGA Monitor input so would I need to get a DVI-VGA adapter to use that video card with this monitor for like 5$ Since this monitor is VGA and the Video Card doesn't have a VGA port,
Also How well do you think this rig will do with simple gaming such as, Minecraft, Planetside 2 and GMOD
