That's not the issue. Your processor is fine for the 260X. Do you have the aux power connected to the card? Card firmly inserted in the PCIe x16 slot? What is the make/model of your PSU?
I dont have any aux cable connected to the card. I'm not even sure if it should. Yes the card is correctly placed and connected to 2 PCI-e express connectors coming out from the PSU (850W). My PSU:
Alpine 850W PC Power Supply Unit PSU - silent cooling 120mm fan, PFC, 4 x SATA
thanks
