Again, nothing like your original.

I said this a couple of times actually.

Not in your original you never did.

This is true. Dunno why you continue to rub that
in though, since it's been established already.

Because you keep attempting to claim that you only ever made
that comment in context and that is clearly a bare faced lie.

In context of the original poster's problem.

Still a lie. The OP's problem had nothing to do with the Power Good line, or
running a power supply unloaded either. In spades with your drivel about amps.

No matter how desperately you attempt to bull****
now, you're fooling absolutely no one at all.

Pity that if it does shut down ITS CLEARLY PROTECTED AGAINST
RUNNING THAT WAY, and if it doesnt shut down IT CANT DAMAGE
ANYTHING BECAUSE NOTHING IS CONNECTED TO IS.

How would it damage something that isn't connected to it?

Precisely.

Where did that come from?

Your stupid claim that it shuts down to protect anything when its unloaded.

Yes, in this case itself.

Still wrong, the supply doesnt need any protection when running unloaded,
it will either start fine unloaded and wont get damaged or it wont start.

In spit of your original claim that has always been just plain wrong.

My original claim is that some won't stay
on if they don't see a load on power good.

Lying, again. You never ever said anything like that originally.
Here it is again.

Yes, and while it doesn't directly have anything to do
with Power Good, such power supplies don't provide
any protection either. If you try to fire up a GOOD
supply and it doesn't observe the correct loads (either
from not being properly connected or from something
that is shorting), it will shut down in order to prevent
damage since it is bad for a power supply to run
without a load. Same goes with amps. If you power
up an amp and crank the volume without speakers attached,
it will either a, gointo thermal shut down, or b, self-destruct.

I have one of them in this computer. If I take away power good, it will shut
off.

Irrelevant to that stupid pig ignorant claim that good power
supplys shut down if they detect that they are unloaded,
to protect themselves against being used like that.

It wont do them any harm even if they can start unloaded,
and most cant, because its cheaper to design them like that.

Case in point, power supply that smoked when it was shorted.

Says nothing useful what so ever about whether it didnt have
ANY protection.

Protection against damage, no it obviously did not.

It just didnt have protection AGAINST A SHORTED RAIL.

And therefore didn't have equipment protection against a shorted
rail. Yes. Well, I also consider this protection against
equipment damage as well - in this case, the supply itself.

Pity you stupidly pig ignorantly claimed that SOME CHEAP
POWER SUPPLYS DONT HAVE ANY PROTECTION.

ALL THAT SHOWS IS THAT THOSE DONT HAVE
PROTECTION AGAINST A SHORTED OUTPUT.

uh huh - and the better ones do.

No one ever said they didnt.

All ATX supplies are supposed to have this protection.
Yet, I have seen cheaper ones that don't.

No news.

Which is what I meant by "don't have any protection".

Lying as always.

Again, in context to the original post in this thread.

Your stupid pig ignorant claim about good power supplys
purportedly shutting down when they are started unloaded
because they need to do that to avoid any damage to
themselves if they run unloaded is completely irrelevant to
the OP's context. He didnt even attempt to use it like that.

AND IF IT ISNT PLUGGED INTO THE MOTHERBOARD,
IT CANT EVEN START, BECAUSE IT DOESNT EVEN SEE
THE START SIGNAL FROM THE MOTHERBOARD ANYWAY.

All ATX supplys are supposed to ensure that nothing powered
from them can be killed if the power supply dies for whatever
reason too, and there are plenty of examples of cheap supplys
that have dies and taken some of what is powered from them
with them when they die.

That is NOT the same as not having ANY protection.

Well they certainly don't have protection against
shorted rails, which they are all supposed to!

No news. No one has ever said they all do.

Therefore, I don't consider this protection!

Separate matter entirely to not providing ANY protection.

If it's not up to spec, it's not what I consider protection.

Separate matter entirely to not providing ANY protection.

Says nothing useful what so ever about
whether it has OTHER protection.

Took out the mobo when this happened,
actually. Not my idea of protection.

Pity you stupidly pig ignorantly claimed that SOME CHEAP
POWER SUPPLYS DONT HAVE ANY PROTECTION.

ALL THAT SHOWS IS THAT THOSE DONT HAVE
PROTECTION AGAINST A SHORTED OUTPUT.

uh huh - and again, the better ones do.

No one ever said they didnt.

So clearly this was a cheaper design that failed to comply with spec.

Duh.

That is what the thread was about.

Lying, again.

OP said it didn't power up because a cable was not connected
correctly.

Pity you stupidly pig ignorantly claimed that SOME CHEAP
POWER SUPPLYS DONT HAVE ANY PROTECTION.

No evidence that the OPs power supply damaged anything.

I never said the OP's power supply did damage anything!

I never ever said you did.

Then why did you even bring it up, saying that there
was no evidence that it DID damage something?

Because you made that stupid pig ignorant claim that
some cheap power supplys dont have ANY protection.

If their protection isn't up to spec, I don't consider it protection.

Separate matter entirely to not providing ANY protection.

That was a JOKE you stupid ****wit. It even had a
smiley on the end for the terminally SOH challenged.

I didn't think it was at all funny.

You have always been, and always will be, completely and utterly
irrelevant. What you may or may not think is funny in spades.

Whether or not that was a joke is also irrelevant.

Nope.

Either way though, it shows you're a raciest.

Nope. It isnt being a racist to say that negroids
tend to have curly hair and black skins either.

Or that asians tend to have black straight hair and inverted eyelids.

It isnt being a racist to tell irish jokes either.

That's too bad, really.

Pathetic, really.

In fact, it comes across that you are a raciest ass is what it does.

It was a JOKE, you stupid ****wit clown.

A joke a raciest would make.

Not a ****ing clue, as always.

Dont laugh, see if I actually give a flying red **** whether you do or not.

DAMN! Someone's got something shoved up his ass,

Just another of your pathetic little drug crazed fantasys, child.

I dont even have an ass, tho I do have an arse.

and it's not me.

Just another of your pathetic little drug crazed fantasys, child.

The spikes are within tolerance.

There is no such animal.

You must have some reallllyyyyy cleeeaaaaaaaannnnn power
then.

Nope, I'm just saying that there is no TOLERANCE to be within.

So you're basically saying that the voltage you get from a
household a/c outlet is a CONSTANT 120, and NEVER fluctuates
at all?

Nope, THAT THERE IS NO TOLERANCE SPECIFIED WITH SPIKES.

If the power supply handles it fine (which they
all do to a degree), then it has tolerance.

Thats not what 'within tolerance' means.

It has to, since household current is not always stable. Storms,
big motors kicking on and off, etc. Again, voltage regulation.

THERE IS NO TOLERANCE TO BE WITHIN.

It has to be designed to tolerate normal and unavoidable voltage
fluctuations.

Duh. THERE IS STILL NOW SPECIFIED TOLERANCE.

I know there is NOW specified tolerance.

No you dont.

You said "THERE IS STILL NOW SPECIFIED TOLERANCE".

That was obviously a typo, ****wit.

And yes, there is.

No there isnt WITH THE SPIKES BEING DISCUSSED.

If the fluctuations are within a certain,
threshold they are within tolerance.

THERE IS NO SPECIFIED THRESHOLD.

But a threshold nonetheless.

Nope.

So then you're saying that a power supply will fail to
work if input voltages changes just by a couple of volts?

Nope, I AM SAYING THAT THERE IS NOT SPECIFIED TOLERANCE
OR THRESHOLD WITH THE SPIKES BEING DISCUSSED.

Glad I don't have any such beast here.

You have always been, and always will be, completely and utterly
irrelevant. What you may or may not be glad about in spades.

If input voltage is outside this threshold, the PS will shut down.

Wrong again with spikes.

Shutting down due to under voltage.

They dont all do that either.

Then they're not up to ATX spec.

Duh.

What kind of protection is that?

They still have SOME protection. Otherwise they wouldnt last long
in the real world with real world mains with the spikes seen on those.

There should still be protection against damage from spikes though.
Cheaper supplies tend to not have as good protection however.

Duh.

Either way, there is a specified range between 100 and 127 volts
(or 200 and 240) in which the power supply should function as normal.

Irrelevant to that stupid pig ignorant claim you made, AGAIN.

If the input voltage remains within this threshold, it is within
tolerance.

THERE IS NO SPECIFIED THRESHOLD.

100-127
or
200-240 as per ATX spec.

That aint the SPIKES you were clearly discussing,
you pathetic excuse for a bull**** artist.

A spike can refer to any short period of overvoltage condition.

Wrong again. That's a surge. And there are
STILL no specified thresholds with surges either.

If a supply is rated for 110 and it gets a spike of 127, that is within
spec'ed
tolerance and the supply is not supposed to have a problem with this. 127
may not be a damaging spike, but it is still a spike nonetheless.

Pity the specs just specify what STATIC voltages
the supply has to operate at, NOT WHAT SPIKES
OR SURGES IT HAS TO BE ABLE TO HANDLE.

An AC supply is not perfectly 100% stable so therefore,
a PS has to be designed to tolerate this to a point.

THERE IS NO SPECIFIED THRESHOLD WITH SPIKES.

again
100-127
or
200-240 as per ATX spec.

That aint the SPIKES you were clearly discussing,
you pathetic excuse for a bull**** artist.

I wasn't discussing spikes!

Lying, as always. Its still there in the first
bit of this sub thread still being quoted.

I only mentioned the word spike - which
can refer to any short period of overvoltage.

Wrong again. We have separate words for spikes and surges for a reason.

AND THE ATX SPEC IS SILENT ON ANY THRESHOLD FOR SPIKES
AND SURGES THAT THE SUPPLY HAS TO BE ABLE TO HANDLE.

A power supply is supposed to handle this quite happily up to 127 - quite
a bit above the juice you are supposed to be getting from a power outlet.

Thats the STATIC voltage that the supply has to be able to hande,
NOT WHAT CAN BE SEEN WITH SPIKES AND SURGES.

And there has to be protection against mains spikes,
otherwise no power supply thats used on the mains will
last very long.

Yes, that is why we have voltage regulators. Again though,
this has nothing to do with the output of the supply being shorted.

Has everything to do with your original stupid claim that
some cheap power supplys dont have ANY protection.

Protection against shorts. Again, context of the thread.

Again, pity YOU also raved on mindlessly about unloaded
too IN YOUR FIRST POST IN THIS THREAD.

I have one running in this computer that will not stay on
if there is nothing connected to the 5v good power line.

No surprises there, its more common than power supplys that will start
up fine unloaded. BECAUSE ITS CHEAPER TO DESIGN THEM LIKE THAT.

Doesnt say anything useful ABOUT ANYTHING GETTING DAMAGED
IN THAT CONFIG. THE SUPPLY JUST FAILS TO START.

You said in an earlier post that ALL power supplies start up fine
and stay running without the 5v Power Good line being connected.

No I didnt. You're lying, again.

quite a while ago I said:
However, on some power supplies, if there is a power
surge or any other issue (which can be caused by a
fried component on the motherboard), "Power Good"
will also shut down the power supply if it malfunctions.

To which you said:
Nope

Which is nothing like what you lied about me saying.

You said that in several posts back.

You are NOW lying about what I said then.

I have a power supply running in this computer that
will indeed shut down if I cut "power good"! PERIOD.

Easy to claim. I dont believe it, you are clearly a pathological liar.

Yet, I have one in this machine that does not stay
powered if the 5v Power Good line is not connected.

Irrelevant to anything I ever said.

Me:
I have quite a few that will shut down if load on PG does not exist.

You:
Fantasy. There are quite a few that will shut down if the
OUTPUT RAILS arent loaded, a different matter entirely.

That claim about the power supply shutting
down if the PG line isnt loaded is pure fantasy.

I have one right here, running my computer.
If I cut PG, it WILL turn off!

Easy to claim. I dont believe it, you are clearly a pathological liar.

And the ATX spec says NOTHING about
that happening, let alone requiring that.

But some still do. I have one!

Easy to claim. I dont believe it, you are clearly a pathological liar.

And completely irrelevant to the OP's problem ANYWAY.

PG, yes. I have such a beast running in this machine.

No surprises there, its more common than power supplys that will start
up fine unloaded. BECAUSE ITS CHEAPER TO DESIGN THEM LIKE THAT.

Doesnt say anything useful ABOUT ANYTHING GETTING DAMAGED
IN THAT CONFIG. THE SUPPLY JUST FAILS TO START.

Again....
You said in an earlier post that ALL power supplies start up fine
and stay running without the 5v Power Good line being connected.

No I didnt. You're lying, again.

Yes, you did.

No I didnt.

You said that what I was saying about some supplies not remaining
powered up if the Power Good line is not connected to anything was
"fantasy".

And it is. There are two parts to that lie of yours above.

First you say there is not a load on power good.

Lying again. I never ever said anything even remotely resembling anything like
that.

There is ALWAYS a load on ANY connected signal line.

Then you say it's cheaper to design a supply that
will not turn on if there is no load on power good.

Lying again. I never ever said anything even remotely resembling anything like
that.

What I ACTUALLY said is that its cheaper to design a supply that needs
a load ON SOME OF THE RAILS IT PROVIDES, before it will start.

The Power Good line IS NOT A RAIL, ITS A SIGNAL.

THEN you say the lack of a load on power good does
not turn off a supply....now you're saying it does.

Lying again. I never ever said anything even remotely resembling anything like
that.

MAKE UP YOUR MIND!

I HAVENT CHANGED ANYTHING I SAID ON THAT.

Yet, I have one in this machine that does not stay
powered if the 5v Power Good line is not connected.

Irrelevant to anything I ever said.

nope.

Yep.

How?

See above.

Yon contradicted your own statement about power
good a couple of times just a few lines above this one!

Lying, as always. You cant even manage
to comprehend what I have actually said.

So why do all amp manufacturers say to never run without a load?

They dont.

Plenty of them do - even for tube amps.

Wrong, as always. And you stupidly pig ignorantly claimed ALL.

And now you're saying none of them say this,

No I'm not, you pathological liar.

which is wrong.

Pity I never ever said that.

See? Even if I say "plenty" which is not "all", you still say they don't.

Lying, as always.

And yet, they do.

Pity I never ever said that.

You just did, by telling me I was wrong when I said
plenty of them warn you not to run an amp without a load!

Lying again. I never ever said anything even remotely resembling anything like
that.

Basically because its cheaper to design it
so that it needs some load to start properly.

Aye.. It is cheaper. It saves them a few capacitors...

There's more involved than a few capacitors.

Hence the need for a load; You'd think they'd
settle for the cooling fan.. but ah well.

There isnt really a lot of point designing to start with no load
because if its not plugged in, there is no power on signal either.

And those care least about no speakers anyway.

Tube amps are extremely forgiving as compared to the transistorized brothers.

Yep, he hasnt actually got a clue about amps, or power supplys either.

Tube amps is a really bad example for claiming
no load kills them. They are hard to kill... very hard.

And they dont get killed running with no load.

He was better off trying to claim transistorized amps
would die without a load.. It was more belivable.

Yeah, he appeared to paint himself into a corner with the
stupid claim about transformers and hasnt got the balls to
admit that stupidity, or he doesnt actually have a clue about
amps except that he does realise that tube amps exist.

And while your forking out the hard earned cash on a good PSU, get a
good UPS as well. What's the point of a nice PSU if you have dirty
power coming into it?

Well, I left out the good part...

I had it connected to a backup-UPS 600 (on it's third set of
batteries). And one reason I bought such a cheap setup is I was
counting on the UPS to protect the darn thing.

When the fluctuation hit the UPS scream'd and the PC died never to
start again, it was at that point I figured the UPS system was no
longer working

I still use the UPS, but as an extension cord, the red power light is
now flashing every few seconds, might loose that ability soon.
