Your power supply rating should be greater than 312.5 watts. I suggest adding 30 watts, which would be 342.5 watts, for future expansion.
That's the result I got on this website:

Currently, I am using 300 watts PSU and without the 256 MB graphic card, everything is working fine. Only the required 3.3 v is coming 3.0 but when I put my 256 MB video it falls below 2.96 sometimes and then I get a warning from Asus probe. (Regardless of the warning things do work fine)
I am not a great fan of installing new things in my computer so I am guessing I would be having these things for a long time without making any additional changes. So just tell me, would 350 be enough to make ends meet?
I just want this 3 v or 2.992 v to go to 3.3 or above. The rest is all good. All the other figures are coming normal. They are both above 12 and above 5. Vcore is 1.573.
