While looking at the specs of the Enermax Noisetaker on the Enermax site, I noticed a small, or should I say, potentially large, problem with the specs of this PSU. Enermax is touting this independent 12V rail system of theirs, yet the second 12V rail is spec'd as being regulated only to within +- 10%!!.. Isn't that way out of line according to the ATX spec? I thought ATX states a regulation of +-5%?
Does this mean that while my CPU and video card are on a nice tightly regulated rail, the other components in my system have the potential to be on rails roughly equivalent to (or worse than!) the +12v rail in crap PSU's you get with a $20 case? I don't like the idea of my hard drives or peripheral components being run on a potentially out-of-spec rail.
The specification grid in the SPCR review of this PSU states that the second rail regulation is within +-5%, but I'll take Enermax's word for it over SPCR's, since the manufacturer *should* know best. And while I DID notice that SPCRs review unit had voltage regulated by +- 2%, but I'm a bit of a skeptic and will always assume that review items are hand picked/tweaked before submission.
Anyway, here are the specs on Enermax's site:

Is this a typo? I was just about to order this guy, when I noticed this. Now I'm worried that buying this unit is a bad idea. *sigh*
HELP!

MikeC's test of the Enermax Noisetaker 475 was WAY, WAY below that, closer to 2%, which you can read up on here:

I'd suggest you inquire at Enermax if they were serious about the +/- 10% differential - that is a tad rich. You are right, ATX in general does mean only 5% variation tolerance, so I am a tad surprised myself...

Your 1st link shows 1A max on 2nd 12V line which is obviously a typo. So I guess that the 5% and 120mV on the tw link are correct vs 10% 50mV (and whatever else is different) on the maxpoint site.
