I should never have tried to upgrade that PC. The OptiPlex 7050 has a weak PSU (power supply unit), so I had to buy a new one (which didn't even fit inside the case), and I could only barely fit a Sapphire RX 580 into the small case. It ended up dying after two months due to overheating. If you want to upgrade a 7050, you're better off buying a whole new computer (but without a CPU) and moving the i7-7700 from the Dell to your new PC.
The OptiPlex 7050 is tiny and has a very weak, I think it's 220W, but the GT710 is low power and usually also small so it might fit, but why would you want to add a GT710 to your system? The 7050 already has multiple display output's and the GT710 is not a powerful card at all, it is only used for extra display outputs.
