So yes you have a second gen LGA 1155 Core i5, with which all of the suggested would work great, not sure if newegg delivers outside US, but the same type of board ould be something to look for, and for what you would be doing with your computer (I assume gaming) youd want to have somewhere between the 600-750w power supply range just to make sure you have more than enough power
this creates some headroom for your power supply (this is good because the power supply doesnt give 100% of the listed power, so just skimming by can lead to a power supply meltdown and can takeout your whole system)
