I have a dell dimension 2400 and i need to know if it is atx or micro atx, can anybody help??? I need to know this so i can buy a power supply. Non of the parts have been replaced or changed, so they are still default, just as how it came.


Thanks

The Dimension 2400 is a micro-tower computer.

These three forum pages imply that the 2400 is Micro ATX.

If you want, you can also measure the length and width of your motherboard and compare it to the MicroATX and ATX standards. The Micro ATX standard is no more than 9.6 in. by 9.6 in., whereas a full-sized ATX board is 9.6 x 12".

It is recommended to have an "SFX form factor" power supply for a MicroATX case and motherboard. You can also use an ATX power supply, but make sure it will fit in your case (i.e. not too long)--you can usually read dimensions of a PSU before buying it. Make sure the position/direction of the fan(s) on the power supply isn't going to harm the airflow of your case; in other words, don't get one that will blow its hot air into your case, get one that will exhaust air out of the case; however, as with any exhaust fan, make sure it doesn't exhaust too much air for the amount of air being taken into the case: huge amount of exhaust + tiny amount of intake air = exhaust fans working too hard/not being efficient enough. Get a good quality brand if you can, as a poor quality one can ruin your whole computer. I know for sure that PC Power & Cooling is a very good brand, except that they are more expensive, but I think you get what you pay for. SeaSonic, Sparkle power, FSP/Fortron (related to Sparkle) and Antec are good brands, too. I think Enermax might be good, too, but I'm not sure.

If you want, you can search eBay for "dell dimension 2400 power supply" without the quotes. I personally bought a very cheap, less-known-name 350-watt power supply that was designated as compatible with a PC I had from an eBay seller that worked for at least several months, then I just stopped using that computer. I think it was around $12-$13 for the sale price, and about $12 for shipping. If these work just as well for what you are doing, you may be able to save some money over the name brands, but I can't say they are as good of quality. I think the case might be that these cheap-o's can handle some load, but don't load them up to their max. In that case, you might want to get a cheap one that has a little more wattage than you need, in case it's bad quality. But it's up to you.
