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
Seasonic makes very good supplies. It has 38 amps on +12v which is enough for a 7770 despite what AMD recommend
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.
