Friend, a PSU will run in your system for the next 15 years, while you will probably upgrade motherboard and videocard and CPU very soon. Its more important to invest in these long term, you need to get it absolutly right the first time. The good news is that you get it once and never worry abut it again.
So, I recommend the Cooler Master Silent Pro, because it is completly silent. I am unaware of Corsair, but get the silent one, PSU noises really disrupt your gaming.
Also, I would sugest getting a $200 videocard, ditch the HDD and invest in a ALL SSD system, you gonna thank me later
