Let me word it differently.

Okay, so let's say there is AC loss. Voltages start dropping. 12V rail hits 11.6V. PWR_OK signal is dropped. That would be AC_LOSS to PWR_OK time. I get that.

Just not sure what happens next. "PWR_OK to Inactive DC loss delay".
 
Turkey, no professor of this stuff at college is going to teach you wrong, and if you are SO concerned that it might happen, then you need to re-evaluate and change majors. Most of your professors will have been teaching this stuff longer than you have been alive. I'm pretty sure they understand what they are talking about.

Also, it seems you get caught up in terminology alot and correcting people. This is well and good but it's a bit much when someone knows what they are talking about and you decide to correct ONE little thing about their wording.
 
Well, it happened to William Beaty, He went to college and became an EE, and said he didn't understand the stuff because he was taught a lot improperly. He had to figure it out more on his own, which is why he wants to share his knowledge with the world. Beaty says he sees engineers all the time who have the same misconceptions he broke himself free of.

I'm not going to like a little college though, I'm going to a pretty good college, so I should have good professors. Obviously not everybody has these misconceptions, but a lot of people do, and I see it a lot on this forum.
 
You just read SO FAR into PSUs here when it is not really that necessary. A place like badcaps.net or other electronics forums would be a much better place for these discussions. Generally people come to a compute hardware forum and ask if a PSU is good or not and it usually is a very simple answer. No need to go all crazy in depth. It's great to know all that stuff, but not necessary for the average PC builder.
 


Then you haven't looked at any of the G1 SuperNOVA units from EVGA built by Super Flower. The SuperNOVA NEX units aren't very good really.
 


I thought those were FSP built.
 
You're right, those are FSP built units. I don't know why I was thinking they were also Super Flower built like the B2 and G2. Chalk that one up for me as a Fail.

I mean, I "knew" they weren't, but for whatever reason, had it in my mind that they were.
 


Being taught in a way that leaves you with misconceptions does not necessarily mean that you were taught something incorrect, just that either you misunderstood the teachings, or they were not as clear as they could be.

I can see your methods confusing people more than helping them.
 


Let me put it into perspective. I picked up a high school textbook on electricity some time back at the library. I read through 90 pages before putting it down because of the incorrect stuff. Here are the problems it made, all wrong stuff:

1) It said that one electron will flow through the wire at the speed of light.
2) It said current flows. It depicted current as some kind of substance.
3) It said electricity can be static *shiver shiver* - talk about an absolutely horrid explanation of static electricity.
4) It explicitly defined electricity as something other than an area of subject. By putting a definition on "electricity", we start to label it, and then when we casually use the term "electricity" we begin to call things "electricity" that are completely different phenomena.
5) It described current is a flow of electrons.
6) It uses voltage as if a single object has a voltage, rather than voltage being a measurement of the electric field between two objects. It fails to explain that in the normal battery light bulb circuit, the voltage would be the voltage measurement between wire A and wire B.
7) It calls voltage electric pressure. Voltage is like an electric pressure, but when explaining voltage in detail, it's not a good explanation at all.

There were a lot of other problems, but I am surely fortunate I went into that book having already read Beaty's writings, because I was able to point out all those mistakes. If I had not read Beaty's writings, here are the things I would think:

1) I would think that electrons flow very very fast, at the speed of light. Which is wrong.
2) I would think of current as some sort of a substance. The more often I would have heard "current flows" I would have started thinking less and less about charge, and more and more about "current" as a "stuff" which it is not.
3) I would be under the same misconceptions of static electricity that so many other people are in. I would simply think that rubbing stuff together would build up some substance called "static" which then goes "zap".
4) I would get totally confused because I would see the word "electricity" being used in completely different contexts. When "electricity" is used in so many various contexts, it just would cause more confusion for me.
5) I would be under the impression that only electrons can flow in a current, which in fact is not true. In salt water, it'd be the protons flowing. When a current flows through your body, it is chloride and potassium ions and other ions that flow, not electrons.
6) I would think of voltage as some sort of mythical thing.
7) I would think that whenever voltage is present, charge must be flowing, but it is not. Voltage is everywhere. Voltage can exist inside of a vacuum, it is everywhere in space. I would lose the connection between voltage and electric fields.

My point is, everybody learns differently. Would these misconceptions harm anybody's ability to make some circuit? Probably not, since they know the math. But for someone like me who cares more about the concepts more than the application of the concepts themselves, misconceptions like this can be a large barrier. They were a large barrier, and now I am free of them. I need more of this:

That makes sense to me.
