Power supply fried, replaced it, computer won't start

Aye.. It is cheaper. It saves them a few capacitors... Hence the need
for a load; You'd think they'd settle for the cooling fan.. but ah
well.
And those care least about no speakers anyway.

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

Tube amps is a really bad example for claiming no load kills them. They
are hard to kill... very hard. He was better off trying to claim
transistorized amps would die without a load.. It was more belivable.

There are generally two things that cause a major smell when they burn
out:

1. Monitor
2. The Case Power Supply

You forgot two.. off the top of my head. A lightning striked NIC card
and modem, god awful smell. :)

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 bullshit
now, you're fooling absolutely no one at all.
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.
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.
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.
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.
If their protection isn't up to spec, I don't consider it protection.

Separate matter entirely to not providing ANY protection.
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.
A joke a raciest would make.

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

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.
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.

There's more involved than a few capacitors.
Hence the need for a load; You'd think they'd

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.

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.

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.

What's a "voltage request"?

Shrug, I likely misworded what I meant, sorry...
Isn't that a current request?

Yes, but with that condition, the resistance level goes thru the roof;
You basically turn the power supply's connections into a heating
element. :(

Millions and millions of ohms?

How hot does a PC power connector with megaohms of resistance get?
