Hi all, I'm new to the forums, and I need help on choosing a Power Supply. My PC is not build yet, that's why I need some help with the Power Supply. Specs are: AMD FX 8120 Eight core Procesor Nvidia Geforce GTX 660 TI 2GB GDDR5 Corsair Vengeance 2x4GB [8GB] DDR3 Ram HDD 7200 RPM 750GB for now. I don't got a motherboard yet, I will probably get a ASROCK am3+ socket MB. So how much Watt do I need with this spec. Thanks!
