i said no overclocking
chances are it will be ok. BUT regardless what was said above, that PSU CAN BE some cheap piece of crap made in china. the company whose name is on the label rarely manufactures the PSU.
as in example:Who's Who In Power Supplies, 2013: Brands Vs. Manufacturers
your power for JUST the i3 and system is less than 100 watts:
add ~110 for the 7850 and IF
the PSU can deliver what is labeled, your fine.
