How do I stop from blowing fuse in mach2gt with a ASUS board?

[FrozenShinobi]

Well my P5WDH keeps turning off the computer when I reset it because of some "cold boot" feature and when that happens my Mach2 goes crazy and blows the fuse. What can I do about this? And if I can't do much, what is the best thing to do when my computer shuts itself off when I try to reset, should I pull the plug on it? Or pull the plug on the mach and then pull it on the computer?

you COULD put in a bigger fuse, but i'de watch it jic cuz bigger fuse means more load meaning hotter wires meaning possible fire

One solution is to run the Mach on a seperate PSU. I do that with a Vapochill.

Fuses will blow from time to time. I always keep a supply of slow-blow fuses handy, just in case.

Replace the fuse with a PTC fuse or circuit breaker. When it "blows", simply turn it off and reset.

Its usualy not a good idea to just keep replacing fuses without finding out why there blowing!!

To me it sounds like when u reset the pc the mach2 compressor is stopping and than trying to start up again too soon and since it can't start it draws lock rotor amps and blows the fuse.

never do this, fuses are there for a reason. to protect from a short or overloaded circuit.

you need to trouble shoot and determine why the fuse is blowing and fix that problem

installing a breaker while easy to reset, constant tripping will weaken the breaker.

Determine if you have a dead short or drawing to many amps, its one of the two causeing your fuse to blow.

Getting a multimeter and tracking down a problem like this will educate you a lot about how your system works. Be careful with electricity.

if he puts a bigger fuse in, and it stops blowing, he could easily figure out what it is, (too many amps were drawn) thus letting him keep his wires intact

Just some words of advice

You measure the amps drawn, thats part of troubleshooting.

There is 2 ways to fix a problem

troubleshoot and measure voltages and loads ,ect to determine the problem or

replace part after part till you eventually hit the correct one.:rolleyes:

Any one can turn a screwdriver or wrench to change a part,But the key is to stive to have the "knowledge" to trobleshoot and fix the item no matter what it is on the first try. This is what employers are looking for. You get paid for what you know.

This is especially true with electronics and electrical componates, one wrong "guess" and that fubar smoke apears.

electrical wires will only carry a certian load(amps) for a given wire size (gage) . putting in a larger fuse than the wire size dictates will cause the wire to heat up and melt the insulation. this may happen immediatly or slowly depending on the over load.

It may takes hours for the wire to heat up enough to melt .

Then all you got is a room full of foul smelling smoke and a piece of melted junk in front of you, or worse no home at all.

No matter what the problem there is someone here that can help you figure it out,all you need to to is buy some basic tools and meters.

The ASUS board is the problem, which I also have. A fix is explained here..

wdrzal, i know over voltage/amprage will cause wires to melt, but if it only happens for second, when the compressor is restarting, the wires wont melt.
i know a little about electronics, and i also know that i dont like touching bare wires that have 120 volts running thru them xD

i do things so that i dont cause harm to myself with electricity, and i know you dont have to touch the wires with your hands, but still, i've seen my brother singe his fingers really bad with just 12 volts in his car

I think there is a firmware fix for it: http://www.extremecoolingtechnologies.com/news/more.php?ID=30
