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?

Re: Changing power supplies.
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

It sounds like some-thing is overheating, an over stressed power supply or poor ventilation could be your problem.
See your power supply is Max 300W that's peak not continuous power output. I think it will only be able to continuously output around 250W of power. Which is below specifications for your computer mainboard.
The Cooler Master Extreme Power Plus range of Power supply's are an excellent choice.
I would recommend a 460Watt with 120mm fan at least.
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.
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.
If nothing was disturbed then this is usually an indication of either the power supply going bad or the hard driver going bad. I start by substituting a power supply of the same wattage or larger. If that doens't work , I change out the hard driver. I believe that is usually a good place to start.
