I'm not very bright when it comes to psu's but i need to know what watt psu I need. This is my planned build but i need a sfx psu for less then 50$. It says estimated wattage is 184 watts but i didnt want to go and buy a 300 watt psu then need a 400 watt psu. I was looking at this PSU but like a said im not sure. Can someone clear this up for me.
