So I recently bought a Corsair TX 650W and a Gigabyte Radeon 7870 to upgrade my old computer. When I finished wiring the new power supply, the computer boots up with my old graphics card (Radeon 7770).
However, when I switched to the 7870, the computer powers up, fans spinning (including the fans on the 7870), lights on, etc, but the computer does not POST. No signal on the monitor and pushing power again turns off the computer right away.
I am currently on my computer running the 7770 with no issues. Could this be a compatibility problem on the motherboard, because I don't think I messed up the wiring. Or do I need to do something before installing a new graphics? I'm relatively new to computers so I apologize.
For more info, refer to my older post before I upgraded my PSU.
