ok i'll see it but are you sure this gonna not let me down as my product had been delivered to me and i saw in system requirement that it needs minimum of 450 or 500 watt certified psu.... and thank you so much for your nice feedback
I think that the Seasonic PSU is a bit pricy and overkill as far as only a 7770 is concerned.
You could save 1200 by going with a corsair cx430.
I bought it 15 days ago for 2938.
I'm planning to run a 650ti on it, which consumes 30W more than the 7770.
