ATX mobo?

[jes]

I have a computer with a baby at mobo and the PSU has the switch on the side for power on/off.
If I were to put an ATX in, would I have to upgrade the PSU too?

Depends...

There were some PSU's that would go
AT/ATX either way.

Best thing to do is check and see if
you have a 20pin inline power plug.

If not and you go to an ATX style
Mboard you will have to swap the PSU.

Hi jes,
I had the same plans; to use some old parts from an AT to build a new ATX system. I had PS supplies out of 166 & 200 Mhz systems and the PS where all different(dimensions/connectors) than what I needed for a new board. The other drawback I found was that these older PS were a lot smaller Wattages than required to build even a lower end ATX machine. From what I have been reading 250W is problably the smallest you would want to go and maybe even a 300W should be considered. They are reasonably priced and can influence preformance and longevity of components added.
IMPO
P.S. I have been trying to go cheap on my 1st build and it is definitely "NOT" paying off. I keep running into conflicts and issues that are costing me addition $$$$$. :o
If you can afford it, go with better quality products rather than basing everything on price.
good luck

One More stumbling point
The AT case and to days ATX M/B don’t match up
The connectors on the back are all different .
If your AT case doesn’t have a removable back plate you’ll have to replace it also
The AT power supplies just don’t put out the Amperage needed to run a ATX system

If you shop around you will find it costs almost the same to purchase a new case with P/S as it does to get a P/S alone

I agree, usually it is more cost effective to buy a case with a psu because there isn't much of a price difference. My local pc shop sells ATX cases starting at only $25.00.
