I plan to buy a new motherboard, CPU, RAM, graphics card, and PSU. I have everything but the PSU picked out. I really just don't know what I need as far as wattage.
Motherboard - ASUS Sabertooth z87 LGA 1150
RAM - Ripjaw 8gb(2x4gb) 240-pin DDR3 1600
CPU - Intel Core i5-4670k Haswell 3.4GHz LGA 1150 84W Quad-Core
Graphics Card - EVGA Nvidia Geforce GTX 760 2GB
Let's assume I will be overclocking -- just to be safe.
