Is this enough for dolphin?

You could choose a lower wattage PSU : http://www.newegg.com/Product/Product.aspx?Item=N82E16817151085&cm_re=SeaSonic_300w-_-17-151-085-_-Product
Pentium G3258 power consumption is low after all
Edit : Sorry , I forgot about r7 265 power consumption (235W on full load) . So 300W PSU won't be enough , 400W then
R7 265 price has been increased compared to the last time I checked it . You may choose a cheaper HDD to cut down the price
