Upgrading GT710 into a integrated system?

I wanted to give my friend my old gt710 but he currently has these specifications:

Amd a6 3670 CPU
Integrated RadeonHD graphics
Msi 7786 Mobo

He has a pre-built pc by zoostorm and would it be upgradeable as it looks like it would be. If it is would the GT710 override the integrated graphics or would he have to disable the integrated graphics?

What is the exact motherboard model?

That card needs a PCIE 16X gen 2. If the board has a PCIE X16 slot it should work. It requires a minimum 300W PSU. What is the PSU wattage?

As whether the GPU would override the integrated graphics or he has to disable it through BIOS he needs to check the motherboard's manual on the manufacturer's site.
