I have just set up my new graphics card. It is a Sapphire Nitro Radeon RX 460 4GB OC edition that uses a 6 pin power connector. My psu is a corsair cx 750M with two pcie 6+2 power connectors, on plugged into the psu and the other end into the gpu. motherboard is asrock 890GX Pro 3 bios ver. p1.40 (upgrading board to MSI 970 Gaming board). My issue is that the gpu fans and leds will turn on when the pc is powered on, but there is no display through HDMI (I only have hdmi because i use a tv and not a monitor), and have the latest drivers for said card. This card is brand new as well. Can anyone help me get it running? I'm tired of using my 2gb gtx 750ti.
