550W enough?How about if i choose 600W?
you can read the review to be assured, 3D guru is a reputable site. well, to be honest i think there are times that they overestimate the wattage of a needed PSU.
the test system they use will draw more power than your ivy bridge unless you overclock past 4.2 and need to raise your Vcore; then they would be the ~same.
if you feel better with a 600 watt then go for it. just keep in mind that PSUs lose efficiency when below a 20% load (~74%). so if you get a 800 watt 80 bronze PSU and idle under 160 watts, which a system does most of the time, your efficiency will be that of a non 80+ PSU.
