Cooling Positive Pressure Case Fan

[joshfinest]

I'm wondering about how I should go about creating Positive Pressure for my case
This is my case and the fan's positioning, number of fans, the size, direction of air flow, and the total CFM.
NLED means not LED

NZXT PHANTOM 410 COOLING SYSTEM SETUP
FRONT: 120mm NLED ABOVE + 120LED BELOW INTAKE
REAR: 120mm LED EXHAUST
SIDE: 140mm LED INTAKE
TOP: 2X140mm LED EXHAUST
BOTTOM 120mm NLED INTAKE

INTAKE CFM:223 (4 fans)
EXHAUST CFM:185 (3 fans)

Will this give me a positive air pressure system? Will my EVGA SuperNova G2 850W 80+ GOLD Certified PSU affect this?

This kinda depends on the size of your case and also the size of your GPU as bigger cards can totally mess with the airflow of a system, but I would use front/back/botton as intake and use the top as an exhaust.
