clutchc :
I can't read the nameplate in that tiny picture. But if it worked with the GT 630 before, it should work now... as long as the rest of the system was about the same as far as... wattage goes.
You can even try the GT 630 with the Thinkcenter's stock PSU if you want to. But if you get shut downs or reboots when gaming, it is probably the PSU overloading.
Yes, a tiny picture...i´m sorry
