I've been searching for a 1000W+ PSU for awhile now and I finally pulled the trigger on a Prudent Way 1000W and so far I'm very happy with it. I know, I know, it's not an OCZ, Enermax, Corsair or other superfamous brand name, but all the rails are super stable with no fluctuation at all. The 3.3V and 5V are probably fructuating -.01 or +.01 only so that's still excellent. The 12V rails are all super stable. They stay 12.10V all the time no matter how much I've stress the system. My prior PSUs, as soon as I run a video card stress test (12V), the 12V started jumping, but with this Prudent Way, you can't see it jumping at all.
 
Just curious, but what are you using to measure the stability of the rails?
 
few seconds on google shows:

prudentway1kw008.jpg

combined total 12v amperage is just over 80 amps..

vs the kingwin abt 1200

looks pretty similar if you ask me.. Oem on the kingwin is superflower.

I will have to take out mine again and take some pictures...

How are you measuring? Bios/Software tools are very inaccurate and should in most cases be completely disregarded.

Using a quality DMM, to measure the voltages is better, but any variations you see there is not really indicative of anything useful in terms of quality. This becomes more relevant when measuring over different loading configurations: 25%, 50%, 75%, 100%, etc. But this is still more a measure of voltage regulation, and not of fluctuation. (that is assuming the power supply in question can even reach 75 and 100% loading)

Using an oscope to measure peak to peak ripple, that would be more appropriate for measuring fluctuations.

I use my DMM to measure...but beyond that, I do have a scope or other equipments to test it...so far it's not doing the thing my older PSUs are doing, so that's all that matters to me.
