Hello people,
i want to upgrade my midget pc, ie , dell inspiron 660s, including the cabinet, ram, psu and gpu.
Following is the specs.
Intel i5 3330s
intel ivy bridge south bridge p75/b75
4gb ddr3 ram
220w psu.
So, is the upgrade possible on the pc? I just only actually want to know if the mother board can take a 400w or more, 8gb ram and atleast a gtx 750 or better. . . .
Or, what is the max config supported by the mobo.
