Hello, thanks for your replay.
Yes your right, i am totally new with this stuff although i have good understanding with terminals as i work as operator. (Making wires for cars/trucks)
So my aim is for 1200w PSU.
The difference comes from how much wattage or by brand ? (Will pick Evga or Corsair, will see by the price).
And can you more explain in depth about capacitors, what they do and what is the difference that i have to know. (Wanna to sell later, so kinda don't want to fack this up).
