What is the quality of my psu

Solution
It doesn't need to be high quality but a decent quality will at least supply the power it says it will. And fsp falls under that decent category. You will be fine with the psu you have but the 630 is not good price/performance. A 6570 is around the same price, uses less power and is better performance.

I don't know where you read a 630 needs a 350w, but the nvidia site says 300. http://www.geforce.com/hardware/desktop-gpus/geforce-gt-630/specifications Though I still wouldn't go by that. You need to take into account every person's specs.
