Hello
This is what I got from asus, checked more than a dozen power
supplies and most only have 30 amps on
the +5 volt, the first 1 found with more was a 620 amp Enermax which has
32 amps +5 volt.
Thank You Joe

Stabilty Problems
The stability problems you are seeing can usually be narrowed down to
1 of 4 things please follow the steps below to see if they will help
resolve the problem you are having.First make sure that your cpu is
not overheating,you can verify this by either checking the hardware
monitor in your bios or by installing the ASUS probe program so that
you can monitor your temperatures, voltages and fan speeds from inside
your Windows op! erating system.Also the probe utility comes with the
option to record one of these 3 things at a time.Go into the history
tab of your probe utility and set it to record and using the drop down
box choose which function you will be recording on,first I would set
it to record temps. until the instability occurs, if you do not see
any change in temp. when the instability occurs then next set the
probe to record temps. and finally fan speeds.If you do not see any
drastic changes in any of these three the the next step would be to
verify the memory you have as compatable with the motherboard you have.
As we do not validate memory ourselves you will need to contact the
memory manufacturer and verify that the memory you have of theirs is a
tested and approved model # and that the cas latency timings being
read in the bios are correct.If the settings in the bios are not the
correct timings ask them for the timings needed to run your memory on
this motherboard, once you have the! se timings either the memory
manufacturer or one of our technicians ca n help you hard code these
timings into your system.You may also want to ask the manufacturer if
there are any memory diagnostic tests that they can recommend that
would also help in determining if the memory is causing the problems
you are having, there are programs out there that will help in
diagnosing problems with memory such as the ones found at
www.memtest86.com or the microsoft memtest diagnostic tool, although
we do not officially support these tests your manufacturer may suggest
one of these I have listed or another that they themselves use.
Power is another issue that can cause instability to occur, as there
are numerous power supply manufacturers on the market it is not viable
anymore to just go by what the manufacturer claims the wattage to be
as 400 watts to 1 company may be considered to be actually only 300
watts to another.With this being the case it is more feasable to
recommend that you check the amperage for each of the voltage rails of
the power supp! ly you are purchasing by looking at the sticker on the
side of the power supply.On the side of your power supply there will
be a sticker that has the dc outputs for each of the 3 voltage rails
supplying power to your motherboard, we recommend at least 28 amps on
the +3.3 voltage rail which supplies power to your CPU and AGP slot,
at least 35 amps on the +5 voltage rail which supplies power to all of
the IC chips on your motherboard and a minimum of at least 18-20 amps
on the +12 voltage rail which provides power to your drives and fans.
these are just recomendations and may need to be adjusted depending on
your set-up and the type of hardware you are using as certain newer
cards ie: sound and video cards are needing more power than some of
their older counterparts.
The last thing to be considered that can cause stability problems is
grounding/emi interferance, take your motherboard out of the case you
have it in and set it up on top of the cardboard box that it came in !
straight to the cardboard or some other non-conductive material such a
s a phonebook or some newspaper, do not use an anti-static mat, foam
or plastic as these have been known to keep a board from posting. Once
you have the board set up outside the case connect up to it just the
needed bare minimums to test for resolution to your stability issues
these include power supply, video card (connected to the monitor), CPU
(w/heatsink and fan), memory and the harddrive with the OS on it. Run
the system out of the case and see if the stability problems you are
having have been resolved, if after testing it out of the case it has
become stable then before you mount it back into the case take some
standard black electrical tape and make a cross over each of the metal
stand-offs you are screwing the board down into mount the board and
screw down thru the tape.This will do 2 things first it will insure
your board against any metal to metal grounds and will also lift the
board up away from the case slightly preventing any EMI interferance
from say a solder ! point that was sitting to close to the case.
If after performing these steps you are still having a problem please
contact our tech support office back at 502-995-0883 and give this
case # to the technician who picks up or contact our RMA dept at
510-739-3777 option # 3 and give the customer service rep. this case #.
