Will AMD A6 6400k work with rx460 or rx 550 or r7 260x?

Solution
Besides not having a good enough power supply, the other possible issue is motherboard bios compatibility. For that we'd need to know what motherboard you have. A program like Speccy can tell you.

as long as your motherboard has a pcie slot, your case can fit the card, and your power supply has enough wattage ( and the proper pcie cables )


they all should work
