That's only 164W total available on the 12V rail.
Considering the 95W just for the X3350, that leaves 69 watts remaining for EVERYTHING else. Motherboard, RAM, fans, hard drive, etc.
Maybe the GT1030 (30W) or something with an equal or lesser power envelope.
I have a Dell Inspiron Small Desktop with a 220W PSU, but it had 18A on the 12V rail (216W total), and I was running a Pentium G3220, a 53W processor. I used an R7 250E, which had a power draw of 55W.
As budgetgamer states, and I agree, I wouldn't gamble the GTX 750 (55W) or GTX 750Ti (60W) on it. It will almost definitely kill it in short order. I would've gone for a 750 on my own system if there was a low-profile, single-slot-height-cooler version, but there weren't any.
Are you looking to upgrade for gaming purposes? It's going to be hard to get much from it with the PSU it has.
