My setup is FX 6300, 8gb of ram (1600MHz), 1tb HDD and a R9 280 gigabyte windforce. I want to know which of this PSU's is the best for this rig. If you could tell me how to plug the PSU to the card, i would be very thankful. The card has an 8pin and a 6pin conector, and i dont know if i have to occupy the 2 connectors. I already have the components and this PSU's are the only ones I can buy in mi situation. Thanks in advance for all the advices and recomendations
