I have been preaching the gospel of industry-standard components in my seminars and in this book ever since. The internals are identical to its industry-standard, high-performance 300W ATX supply (which it sells for about 30% less)—only the number and arrangement of wires has changed. All standard PC power supplies that use the P8 and P9 connectors have them installed end to end so that the two black wires (ground connections) on both power cables are next to each other. The issue is not whether the power supply can generate the necessary 12v—that has always been available via the peripheral connectors. The difference is that Dell has Intel custom-make the boards for Dell with the nonstandard connectors. Figure 3.6 The P8/P9 power connectors (sometimes also called P1/P2) that connect an AT/LPX power supply to the motherboard. Unfortunately, if you study the Dell main and auxiliary connector pinouts I've listed here and compare them to the industry-standard ATX pinouts listed earlier, you'll see that not only are the voltage and signal positions changed, but the number of terminals carrying specific voltages and grounds has changed as well.
