Power supply question

[BP]

I have an older MicroATX case, and have recently purchased a new
motherboard/CPU. The CPU is an Athlon XP 2500+. The old power supply was
only 145 watts, but the minimum wattage AMD recommends is 250 watts.

OK, all of that to say this... I could not find a 250+ watt micro ATX P.S.
locally, so I bought a 300 watt ATX P.S. because there appears to be room to
mount it in the case. My concern is that the P.S. will be pretty close to
the CPU when it is installed, and I am afraid it might get a little warm in
the case. Is this a legitimate concern? Am I going to run into any other
issues by using this ATX P.S.? Thank you for the help.

that is definately a problem with those small cases
the psu can block the cpu cooler's air flow.

your choice is to re-case the system
or else make a bracket that allows the psu to be mounted a few inches
out the back of your case.
i;ve done that a few times
and though the machine may look a bit odd when viewed from the rear...
it seems a better choice than viewing a fried cpu

Use motherboard monitor to keep an eye on your CPU temps and board temps.
That case is probably too small.

A new case would cost less than a new power supply. (Around here you can
spend $29 Canadian and get a mid tower ATX case with a 350watt PSU - Of
course the PSU is crap, but it does work for the average PC)

Thank you all for the responses. I decided to go with the new case. I just
wish I would have done this before buying the micro ATX motherboard. Live
and learn, I guess. Thanks.
