At most I'd recommend a GT1030.
But those PSUs still aren't built for dedicated GPUs.

+1 on GT1030 (low profile).

Given that the CPU is only 55W, I think going to a 75W GPU should be relatively safe. Still gives about 60W for everything else.

It might be risky, but might be doable. Otherwise, yeah, the GT1030 is the safe bet.
