Dell motherboard diagram of wiring and front pannel connectors


most front panel connectors with a 4 x 5 pin configuration are intel compliant, and are all the same.
The "nine" pin is missing, and is the "KEY" to orientation, no matter which way the pins are situated on the board.
1 3 5 7 X
2 4 6 8 10

1= HDD LED+, usually green
3= HDD-, usually white or black
2= PWR LED+, usually red
4= PWR LED-, white or black
These are polarity specific, and must be connected to the proper + and - terminals to work properly

5= RESET
7= RESET
9 is missing, can be used to determine location of other pins
6= PWR
8= PWR

Thes are momentary contact pins, can't get them backwards

Pins 6 and 10 are jumped together in the Dimension 2400.

Will a NVIDIA GeForce gt 610 graphics processor work on a Dell Dimension 2400 PC Desktop


YES, Zian it will work....BUT,....................

1) It is a PCI graphics card, and uses a PCI expansion slot.

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=2898922&CatId=319

The Dell Dimension 2400 Desktop PC's motherboard, has three long white PCI slots,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105465

http://www.ebay.com/itm/Dell-Dimension-2400-Desktop-Motherboard-System-Main-Board-F5949-K5148-G1548-/190750417467?pt=Motherboards&hash=item2c699c623b

http://en.wikipedia.org/wiki/Conventional_PCI

If one of those long white PCI slots is open, you can use a PCI graphics card.

Concerned that the graphics card uses DDR3 graphics memory, and your computer only uses DDR Sdram ram memory?

Don't be.

The graphics card has it's own processor (Graphics Processing Unit), and graphics memory.
It runs independent of the system resources; the Processor and Ram Memory.

http://en.wikipedia.org/wiki/GPU

The concern is the Power Supply.
Original power supply's maximum rated Wattage is either 200 Watts, or 250 Watts.

The above graphics card requires a minimum system requirement/power supply requirement; of 300 Watts.

I would recommend replacing the Power Supply.
(Especially with it's age, if it is still the same one)

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1389575&CatId=1078

ONE thing though..............
Watch the 20-pin ATX main power cable connector, and the wires in it. Be sure they are in the standard place setup.

Check the pinout, and color code of the wires,

1) Dell Dimension 2400 desktop computer, 20-pin ATX main power cable connector pinout,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105612

2) STANDARD 20-pin ATX main cable connector pinout, and color code of wires; as set by JEDEC,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

[Be aware that the ATX main power cable, and connector, you get with a new power supply; such as the above, will have a 20 =4-pin ATX main power cable connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

Use the 20-pin connector, tie the 4-pin power cable up out of the way]

For a time period Dell was making the motherboard's main power cable connector - Proprietary.
Meaning they has that motherboard connector wire pinout changed.
Colors of wires were in a different place, than the standard setup by JEDEC.

Orange wires are 3.3 Volts (DC)
Red wires are 5 Volts (DC)
Yellow wires are 12 Volts (DC)
Black wires are Ground wires.

Guess what happens if a 12 Volt Yellow wire, is plugged into where a Black Ground wire is supposed to be?

ZZZZZZzzzzt! Motherboard fries, processor fries, ram memory fries, and graphics card. (If used)

Check the color code of the wires, in the 20-pin ATX main power cable's CONNECTOR, for the Dimension 2400's power supply.

For additional questions please post in a Comment.

MY DELL DIMESION 2400 WILL NOT TURN ON PUSH THE BUTTON I GET NOTHING.


hello facawthon

if there is no response as you said then the most likely cause of it could be the power supply. it is not expensive to replace and all you nee for a dimension 2400 is an ATX power supply around 400 to 500watts.
The dimentions of the power supply is standard wht you have to pay attention to is the back of the power supply. some have two connections (power in and power out) some have two connections and an on-off power switch, and there may be only one connection with or without the on-off switch. All of these are OK, but some Dell cases can take the ones with only power out connections because the back of the case does not have an opening wide enough for others.

The bes thing would be to take the exising one with you if you decide to buy one.

hope this has put you in the right direction.
please leave comment if this was helpful.

How do I check a dell dim 2400 pwr supply w/o using a mohterboard?


Sorry you are having trouble.

The easy way to take it to Fry's or Best Buy and let them check it.
The other way is to jumper the proper pins on the connector together and use a volt meter to verify that the voltages are within an acceptable range.

Dell Dimension 2400 that has had a power surge


Um, unless you are happy soldering VERY finely and under pressure then go for it, but to be honest, you can pick one up for £30-£50 that will have everything you need and more!
