Question about Dell OptiPlex GX260 PC Desktop

1 Answer

Missing power supply. First, thanks to fredtmccoyjr for the boot fix. the BIOS update from A06 to A09 actually allows me to enable boot from harddisk in the settings, instead of settign a useless tick on the menu. Heh... The toggles; they do nothing. Two of the other units I have lack working power supplies, and none of my spares are ATX-24/P4; but I do have spare ATX-28/cluster, ATX-20/P3 and a pile of matching BX backpanes. I can build an adaper to use either the ATX/blah units with some more information. I need to know does this model of Dell confirm to the 'standard' ATX pinout, or do I need to make a cardedge adaptor out of a spare backpane?

    Thanks;
    6/17/2002 seemed a little close to the last time this bit me and I was not confident that the 4 pin molex connector took 12V and not 3V3. I can to do a continuity check to see which pins are ground and 5V to be certain about the main connector.

It was the 1996 to 2000 time frame, that Dell was proprietary with the 20-pin ATX main power cable, and the matching connector on the mobo. (MOtherBOard).

Standard 20-pin ATX main power cable, and it's corresponding connector should work, then add the 4 power wires that are missing, in a separate connector.

To expound:

View this standard 20-pin ATX main power cable, and it's respective connector,

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

The power wires should be in the same place as your P3 units.

(Match the color codes.
Use the lock tab on the 20-pin ATX main power cable connector, to base where the pins are.

Pins 1 though 20. Match the color code of the wires to the pins, and use the chart to compare)

Here is a view of a standard 24-pin ATX main power cable, and it's respective connector, so you can see what power wires are missing, from the 20-pin ATX main power cable connector, that are present in the 24-pin ATX main power cable connector.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Note the missing power wires, and what pins they line up with.

The P4, or also stated as the 4-pin ATX +12 Volt power cable, uses two Yellow (12 Volt) wires, and two Black wires, (Ground)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Since you don't have the male connector, be sure to orient in your mind where the Yellow (12 Volt) wires go, and the Black (Ground) wires go, by looking at the lock tab on the side of the female connector, on the motherboard, and comparing it to the photo.

Transfer this info, to the P4 connector you are going to make.

Where to get the power wires you need? Connect to any extra 4-pin Peripheral power cable wires, or splice off of ones that are in use, is one suggestion.

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

The links given are near the middle of the page. Scroll back to the top. Left-click on any power cable connector, that you wish more information on.

More info,

Scroll to the bottom of the page, and look at the chart under the heading -

24-pin ATX12V 2.x power supply connector
(20-pin omits the last four: 11, 12, 23, and 24)

Make sure that there is no power failure during bios update and you have a power back up of atleast 10-15 minutes. Download the update from Dell's website and double click on the .exe program. Wait for program to finish the job.

Put in new power supply, computer will not boot up. Asks what type of power supply, when I answer generic the computer will not continue to boot up. When I go into bios it says power supply is disabled and...


Try resetting the BIOS, depending on the motherboard, there will either be a button, switch or small jumpers that will short two pins and reset the cmos on the board. Just make sure to take out all the extra peripherals before powering back up. If you have jumpers, look for the one marked CMOS, not the one marked password. Move the jumper plug over one pin and power the system up. Wait approx. one minute and power back down, remove the power plug from the back and press the power button on the front to bleed off the power. Move the jumper back to its original place, plug the power cord back in and try booting the system back up. If it boots you will need to restart and get back into the BIOS and reset the time and date.

Dell optiplex wont boot up


If you are using a USB keyboard, then check in the bios that USB keyboard is enabled, and also Legacy support as well.
Legacy support will allow a USB keyboard to operate under the DOS environment.
This should allow you to press the any key to start booting from CD.
Hope that helps =)
