Searching for a quality psu

post #1 of 7
Thread Starter 
The 520 seasonic unit i picked up is nice but i notice it has some moderate coil whine under load and during idle (very quiet then). This specific psu seems to have plagued me with video card based coil whine on several cards (7950, 7970, 670 etc, varying for each card) for reasons I couldn't explain or pinpoint. I've spent the past 3 days looking for a quality unit that will last me awhile. There are several aspects I'm looking for at the moment: low ripple, modular/semi modular, solid voltage regulation (3%), and between 600-700w. I don't plan on running dual gpus, I will be water cooling in the future, I expect anywhere form 5-6 ~120mm at most, 2 hard drives, and a cd drive plus my sig rig(which will be oc'd further after i delid and get water). I'm tired of coil whine issues as my rig is already incredibly quiet and It can always be heard above system fans/components under load.

I've specifically looked at the Corsair HX650, Seasonic 650 X series, Enermax 750 NAXN, Rosewill Capstone 650M. They all seem to have their issues and I specifically don't want to deal with the HX650 or the seasonic due to the common chirping with the corsair unit and many seasonic units seem to be getting reports about coil whine. The Enermax looked nice but did poorly in ripple tests and the Capstone does not have an MOV. Stuck on making any choice atm, budget is around 120$ any help would be much appreciated.

How loud is it/does it get in comparison to system fans etc... any ballpark comparison will do

About as loud as a gelid silent 120. In other words, silent.

I haven't heard reports of coil whine with the Rosewill Capstone line. I'm sure it's theoretically possible, but unlikely.

I use a Corsair GS 600, and its wonderful. Going with the HX Series would be another step up, go for it man.
Plus the warranty's pretty swell.
