Dell's official explanation for its lack of conformance to the ATX standard was, "In the mid-90s the industry moved to a higher use of 3.3v motherboard components. Never plug any GPU cable into the PD_12V. I've never used a 6 pin connector, most of my old PSUs only have the 4 pin type, that's why I looked at it so closely. The terminals used in these connectors are rated to handle up to 5 amps at up to 250V (even though the maximum used in a PC is +12V). Your system may need -5V which modern ATX PSUs don't have (some but not all older ones do) AT power supplies are not controlled by the motherboard but by a seperate power switch. Motherboard power pin are universal. This adds a third power connector, called the ATX12V connector, specifically to supply additional +12v power to the board. Therefore, adapting a standard LPX form factor supply to make it work properly in an ATX system, is difficultif not impossibleeven though the shapes of the power supplies themselves are virtually identical. Thus, the remote switch in an ATX-style system (which includes NLX and SFX systems as well) carries up to only +5v of DC power, rather than the full 115v230v AC current like that of the older AT/LPX form factors. The ATX standard specifies that a voltage of +1v or less indicates that the fan is to shut down, whereas +10.5v or more instructs the fan to operate at full speed. It was then that I discovered, to my horror, that LPX systems were not an interchangeable standard. Melted connectors were becoming more and more common as these wires overheated under these loads. Most of the power coming from the 12V connector is often used to power the CPU. However, because ATX is a superset of the older AT standard, you can use an adapter to allow an ATX power supply to connect to an older Baby-AT style motherboard. Pearson may offer opportunities to provide feedback or participate in surveys, including surveys evaluating Pearson products, services or sites. Of course, building your own system from scratch is one way to avoid proprietary components, but often that route is more costly in both time and money than purchasing a prebuilt system.
