Hello! I am building my first PC, intended for gaming, and I am nearly complete. The only thing that I am still uncertain of is my power supply. I was thinking of going with a 750 watt corsair, but I do not know if I am over shooting the amount of wattage that I need. I will post the full build down here, and any help at all would be greatly appreciated! Mainly I would just like to know if this is a decent power supply, or if I should get something else.

i think 600-650watt would be enough for your system,but if you are planning to upgrade to a more power hungry graphics card in the near future,you could opt for a 750watt,this link is for a modular corsair quality psu in australia,you may need to search this product in your country..good luck
