Dead Mesh PC

Hello PC Advisor Forum Members

It appears my Mesh Matrix (Althon XP3000+)
has finally given up the ghost.
I am unable to switch it on at all, no boot up, no beeps nothing.
I tried changing over the mains cable, but nothing
works.

I suspect the (PSU) power supply unit has gone.
The question is how can I be certain it is the PSU and not the processor?
Also, what type of PSU should I use as a replacement, is 500Watts the correct type??


I do hope you can advise me.

Many thanks to you all

Any [known to be working] PSU that you can get your hands on will do to test it out see if it boots, Rogmur. If it turns out that the PSU is to blame then you can install one appropriate to your PC's power needs.

500 w should be ample for a Althon XP3000 if it is indeed dead.

PSU TEST

If renewing a PSU check:

1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp.
3 The correct connections for your equipment

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.

3. Correct connections
Some boards have 20 pin connectors others 24 pin
There is often a 4 pin plug required to power Intel CPUs
Molex D plugs for IDE HDD and CD/DVD drives
SATA power connections for latest HDDs and DVD drives.

Many thanks to you all, for your sterling advice.
I shall check out the links you have provided,
my defunkt PSU is an ATX 12 Volt, total power is 360. (I should imagine it is going to be fun trying to install a new one).

Once again my thanks to you all.

Using any PSU can do more arm than good you should get one that will handle the currant, as if it blows it may take out MOBO and CPU plus Hard drive etc. I know as it did it to one of my comps.
This supposing that it’s not already done it
