Old Dell mid-tower case power button adapter ??

Postby moconnor6105 » Thu Sep 27, 2007 4:20 pm

I want to do a new build using an old Dell case that originally ran a P II. I think it will work but the power button (and hd light and reset button I think) are all controlled by one small board that is connected to the mother board by a small ribbon cable vs. each having their own wires. Is there an adapter available to convert these or do I have to spring for a new case ? If there is an adapter what is it called and where might I get one ? The only local store I can think of is Radio Shack. Thanks.

I tried using a "Point of View Gun", but my aim was lousy. ;-)

ASUS K8N, AMD Sempron 3100+(1.8ghz), 1gb RAM, eVGA 5500FX 256mb AGP, two WD120gb SATA drives in RAID 0 (striping), 450w power supply.

Fold well, so that others may prosper.

Dell power supplies
Older Dell computers, particularly those from the Pentium II and III times, are notable for using proprietary power wiring on their power supplies and motherboards. While the motherboard connectors appear to be standard ATX, and will actually fit a standard power supply, they are not compatible. Not only have wires been switched from one location to another, but the number of wires for a given voltage has been changed. Thus, the pins cannot simply be rearranged.[3]

The change affects not only 20-pin ATX connectors, but also auxiliary 6-pin connectors. Modern Dell systems may use standard ATX connectors.[4] Dell PC owners should be careful when attempting to mix non-Dell motherboards and power supplies, as it can cause damage to the power supply or other components. If the power supply color coding on the wiring does not match ATX standards, then it is probably proprietary. Wiring diagrams for Dell systems are usually available on Dell's support page.

Thanks for the posts. Unfortunately I cut class in electrical engineering college when they talked about ATX power supplies and the link is a bit above my head. My build parts, MB, CPU, etc... are showing up today and don't know if I want to wait for more parts to mod the case. I think I'll (gasp) just go out and buy one (double gasp) retail.

Sounds like a good (and safe) idea to me. Enjoy. 8)
