Hi all, I am looking to buy a 750 ti most probably the MSI version but my question is that I will be fitting this graphics card into a pre built tower which has already got a 230W psu installed as standard, I have read that I do not need to worry about the power supply as these cards use low power consumption so would I be fine just installing the card without the worry of frying it or other components ? also would it bottleneck an Intel i3 3240T 2.9Ghz cpu ?
