I suppose the assumption is that all power supplies of similar wattage are created equal, but that couldn't be farther from the truth. PC power supplies can differ in not only more obvious environmental attributes like noise and heat levels, but also in the quality of power they deliver.
Today, we've rounded up five brand-new power supplies from Ahanix, Antec, Enermax, Vantec, and Zalman to compare with each other and our previous favorite. We've updated our power supply testing gauntlet, too. Not only will we be looking at DC voltage tolerances and noise levels, we'll also take a peek at each power supply's impact on system temperatures and measure its AC ripple voltage. Which power supply stands out from the competition as the quietest, coolest, and cleanest source of PC power? Read on to find out.
