Yea, it was funny of him to tell me and a couple others that UPS's don't
protect from surges/transients, and then change the story to cheap UPS's
is what he meant.

I saw that, which comes back to the idea that he is sucking out more
amps than the PSU is really rated for. Cheapie PSUs use a fuse so when
it blows then the PSU is useless (except for those willing and capable
to do the repair). So his 400W units really can't put out anywhere near
that and can't even manage to handle whatever is his real load. I've
seen cheapie PSUs that couldn't manage to provide half of their rated
wattage, and 200W is probably too low for his computer.

I bought a couple really nice Antec 550W PSU units, they were nice
except for one little flaw - they contain two variable speed fans that
run based on temperature of air flowing through the PSU. I found that
the fans ran around 1100RPM and were unable to keep the system cool, I
opened the cases and setup the fans to run on a fixed +12v and they run
around 3500RPM and the systems stay a lot cooler now.

I didn't misunderstand..
I was just so glad that the little fuse in the PS saved a life, is all.. lol

Being a former electrician your AC circuit is not grounded. No amount of
surge protection will help you . Surge protectors rely mainly on the
circuits ground fault to discharge a surge in the line when it happens.

Hi all,
FYI the machine has been accepted back by the business who built it to
be repaired under warranty.
I have passed on the relevant suggestions posted on this thread and
hope they pull it down and check it according to your suggestions.
Thanks again and I will be sure to post the outcome. However it may be
a couple of weeks?

Just make sure that you install a quick-acting fuse in the shower matt
so that you are fully protected from slipping in the shower

These undersized power supplies are why the 3.5 digit
multimeter is so much a powerful tool. Simply power up the
machine and measure all critical voltages. Then have machine
access all peripherals simultaneously. Play music on sound
card while each Command Prompt program accesses a disk drive,
CD-ROM, and floppy simultaneously. Access other computer disk
drives on the network. And use the internet. Do all
simultaneously and measure those voltages again. If the power
supply is sufficiently sized, those voltage will remain in the
upper three quarters of those defined voltage limits.
This does not mean the power supply contains other essential
functions - a good condition. But it will identify inferior
supplies - a bad condition. This load test being effective to
identify a sufficiently sized power supply - to confirm what
they claim in writing probably does exist.
What is so often missing in supplies that can't provide the
power as claimed? A long list of written and numeric specs.

Why do codes call for protection of that wire? A wire
destroyed by too much current causes fire. Fires threaten
humans. The wire is protected by fuse firstmost because a hot
and burned wire creates a threat to human life. We are not
first worried about the wire. We first worry about the
human. A primary function of fusing is protecting humans from
failure. Fuse may perform other secondary functions. But its
primary purpose as even defined by codes is human protection.
Fuses typically blow after hardware has failed. Fuses
typically do not just protect hardware.
Why would that fuse inside his power supply blow? Hardware
damage has already occurred. Did the fuse protect the power
supply from damage. Not likely. The fuse blew after damage
existed.
Next you will tell us how some UPS provides protection that
its own manufacturer does not even claim to provide.

Why do we fuse vehicles wires? Fuse also protects those
wires. But again, the primary purpose is to avoid car fires -
a threat to human life. Overloaded wires cause fires - a
threat to human life inside that car.
What happens if the power amplifier outputs excessive
power. Well clearly something inside that amp has already
failed. The fuse did not protect from the failure. It is
simply disconnecting as a result of the failure. Maybe it
will protect more transistors from failing in succession. But
a failure existed before the fuse blew.
The fuse blows typically when hardware has already failed.
#1 reason for fuses? Human safety. Why do we fuse to protect
wires? Again, number one reason to is avoid wire fires -
human safety.
Your links were for circuit protection devices such as TMOVs
- not for fuses. Circuit protection devices are not fuses.

Right. You protect the DEVICE, which in turn may save someone's life - or
not!
I have NEVER seen a fuse protected device prevent someone from getting
electrocuted if he stuck his hand in the control panel and grabbed a 220v
terminal, have you?
Therefore, a fuse does not protect human life directly. The human protection
is ancillary to protecting the DEVICE!

I said fuses protect human life. I did not say humans will
always be protected by fuses. But when a fuse blows, its
number one purpose is so that humans are not harmed.
Fuses are installed to protect humans. That does not mean
fuse will protection human from falling in the shower. That
does not mean a fuse always protects humans. But still fuse's
primary purpose as even defined by code is to protect the
human.
Returning to the original point - the fuse in a power
supply blows because hardware has failed. The fuse did not
stop hardware failure. It will stop further damage (ie fire)
as a result of that failure. Its' #1 purpose - to protect
human life. Protecting additional hardware may be ancillary
to its primary purpose often because that ancillary function
is necessary to protect human life. But a fuse did not stop
power supply damage. The damage occurred. Then the fuse blew.
A line cord fuse as used in UK does not protect the
hardware. If blows after damage has occurred. So that damage
does not harm humans, the fuse blows.

You are such a lamer. The fuse blew because the load was greater than
the rated value of the fuse for a longer period that the rated time for
the load.
It has nothing to do with Damage, it could simply have been an
undersized fuse in a product lot/batch or it could be an over-loaded
power supply, or a peripheral in the throws of going bad (but not
"damaged").
I don't have to tell you anything, you know it all, and I've never
stated that a UPS does anything in relation to the vendors documents,
I've only made my many years of using quality UPS devices in the
experience of many conditions present in this group.

You are so completely full of sh1t!
Fuses protect devices, which may or may not endanger anyone or anything,
they are to protect the device from damage first and foremost.
GFI breakers protect Humans, get your devices figured out before you
post again.

As another has already said "Horse Shit". Fuses protect wiring and
devices, they are not there to stop a fire specifically.

dang, I just figured it out - my new keyboard has a small fuse inside

from being on a keyboard 8+ hours a day
