To ATX or not to ATX?

How do you differentiate an ATX casing from a non-ATX casing?

I bought my Athlon XP 2600+ within the past six months; does that mean it's pretty likely to be an ATX?

It's 100% certain to be an ATX case and PSU.

ATX has been with us for quite a number of years now. In fact about Pentium II time if I remember correctly!

the one before ATX was AT. those normally had a thing for you to plug in your monitor as well, and were low powered and had different mobo connections

AT also had a 5 pin din keyboard and a serial mouse. ATX has PS2 keyboard and PS2 mouse.

I think the ATX form factor was introduced by Intel back in 1995.

I am very confident that a PC bought within the last six months would be ATX.

Thank you all. My reason for asking is that I wish to replace my current PSU with a 400W dual-voltage input PSU (as I'm travelling to Jamaica soon). I've found that some PSUs are ATX while some are not. I think ATX PSUs won't work in non-ATX casings. But since you all say mine is very likely to be ATX, then I'm no longer frustrated. :)

A 400W PSU would be more than enough to handle Athlon XP 2600+ right? Or would I be better off with 450W or 500W?

a 400W would be more than enough for a 2600+ CPU but it also depends on your other components although unless you have multiple cd-roms/hdd then 400 will do.
