I have Rx 560 4 GbDon't plug any 4 pin into your 6 pin GPU. You can try no power plug, sometimes that will work if the card draws less than 75W under load, but if your 650W PSU doesn't have a 6 pin pcie cable, then you need to get a new PSU.
What exact model is the PSU, and which model of RX 560 do you have?
There here are lots of manufacturers of that card, and some have different power requirements. The same manufacturer might even make different versions of an RX 560. That isn't even as important as the PSU though, because we know your 560 requires a 6 pin. You don't have a 6 pin. Since it draws 75 watts, I'd try it mith no PCIe power connected, it may work since it's only a 75 W card. It might not though, in which case you'd need a new PSU. Do not plug anything into your GPU that isn't a 6 pin connector.I have Rx 560 4 Gb
