Changing power supplies.

I changed out an m863g motherboard. The power comes on and shuts down in seconds. Is it beacause the 300w power supply initially used in this system has been changed to a 500w? Or does that really matter?

    My problem is almost the same but i think i caused it my self. I went into the bios and changed an option in PC Health line. There was an option saying that bios/motherboard can monitor CPUfan speed in case of any failure- I enabled it. I saved changes and restarted my PC - from that moment my PC starts for a few seconds during which bios gives 3 identical signals and the PC shuts down (power off).

    Hardware: Maiboard - Spacewalker AK12a, Bios - Phoenix. I tried to reset Bios but it doesn't change a anything. Please help me!!! :)

Yes and no I do not now the min power for that one but I would say it would be a good ideal one way or another cause 300w will not cut it for when you hook up you cd/hard drive/motherboard but I can not say that it is something else that is causing the issue so what would be best is for you test it with another power supple and if it does not work we will take it form there

I WOULD LIKE TO KNOW IF I CAN USE A 300W POWER SUPPLY UNIT FOR THIS ASUS K8V*MX


The wattage rating is the maximum power draw that the power supply can supply. If the system only requires 200W, only 200W will be delivered by the power supply. It is recommended that the power supply rating be higher than what you expect to draw so that you never draw more than 80% of the total capacity. In other words, if you expect to draw 240W total, use a 300W power supply.

So, yes it is fine.

It is most likely your power supply. You can try buying one and changing it out. But it sounds like its the power supply, and don't keep trying to turn it on, if the supply comes through weak or bad-sine it can harm the motherboard.

These switching power supplies MUST HAVE A LOAD on them to work properly.

Often, without load, they spike up to overvoltage and OFTEN they will immediately shut themselves down.

If you found a shorted diode, likely there may have been a second one that is defective as well. A bad diode will often unbalance the regulation of the unit.

Motherboard shuts off


You may want to try using another power supply rated at 300W plus. Also make sure your RAM is unbuffered and non-ECC. To set the switch correctly, you need to goto look at the exact model number of the CPU. Because CPU with similar marketing name could have different front side bus speed.

One more thing to look for, make sure there is no metal standoff sticking out of the bottom of the case shorting out the mother board. But my first guess is the power supply.

It is a little hard to tell, I dont think its a psu problem.
I have seen something similar when a cpu/motherboard went faulty. (Older machine could not get either cpu or motherboard to test)
Also worth checking your ram is seated correctly.

From 300w psu i change it to 450w will that be ok?


Ivy My field is in home appliances. I do fix my own computers and have replaced a few power supplys. The only thing I could say to you is go back and recheck your connections. They should only fit on the bord one way. The other connections for the hard drive and cd drives and so on really dont matter. so good luck and I think if you recheck it all the computer will work.
