The Corsair 750 is starting to reach the limit for that particular platform, but ripple is still within specs. It is higher than we would like, so when compared to other PSUs, it is about the only place the Corsair is lacking. But as long as it stays within specs, there's no problem. As for the Zalman, I don't think I've seen a ripple test for the 750W, but the 600W can be found here: http://jonnyguru.com/modules.php?nam...Story3&reid=30
. As you can see, there's barely any ripple at all. If you compare to other Epsilon based PSUs like the OCZ GameXstream 700, even at about 500-600W ripple is out of control: http://jonnyguru.com/modules.php?nam...Story2&reid=24
. It's obvious Zalman was able to tweak whatever was wrong with the FSP Epsilon line, and fixed it's only real weakness. That makes the Zalman a very nice PSU.
