I have recently got a new 1060 6gb graphics card . However when i went to install it i could not i plugged it in and turned on my pc and it said plug in the power connectors (a 2×4 pin connector) but i only seem to have one on my power supply. Do i need to buy a more recent psu (mine is old). If so i was looking at the EVGA - 600W 80+ Certified ATX Power Supply. Will this be sufficient?
