Needing to plug new power source to motherboard, need the diagram format

Is that a question or a statement? If it is a question, you need to include the device your needing the power wiring for, I'm guessing it is for the E-Machine, and if it is, the power is the same as any motherboard and power supply, it has a unique connector and it makes the power supply connector only able to be plugged into the only jack it will fit.

West Marine has a lot of compatible aftermarket parts. The wiring diagram for that boat will be hard to come by. If you buy a signal tracer at Lowes or Home Depot, you should be able to backtrace the power source from one of the wiring leads where the old connectors plugged in.

A place around Detroit, called "HELM" publishing can sometimes supply new books for a very high fee. Fortunately Bayliner is still in business and may be able to help you. Just do some web browsing for there contact info.

Hello,
For your system to boot up properly, you need an identical power supply for your system. Most likely the reason why your system won't boot up right now is because you purchased a different power supply and it is lacking something(which is the other pin).

New motherboards have a 24-pin power connector. Here is a diagram of both plugs:



You can see that the two are almost identical. The extra 4 pins on the 24-pin connector provide extra connection points for a few voltages. Newer boards and processors need more current, and the extra pins were added to prevent overloading.

Adapter cables are available to go from your 20-pin power supply plug to the 24-pin motherboard connector. Here's one from TigerDirect, and other vendors have them as well. If you're not making other changes than replacing the motherboard, you shouldn't need more than this adapter.

If you are upgrading your processor along with the motherboard, you should probably replace the power supply too. Older power supplies are often in the 300-watt range, and this is too low for reliable operation with new processors, motherboards and video cards. A new 500 or 600-watt supply is not expensive, and would give you the 24-pin power connection the motherboard needs.

Hope this has helped. Thanks for using Fixya!

A Computer Motherboard Diagram Once you know what you are looking at, you can recognize the components on any motherboard layout. A computer motherboard diagram is very useful for when you need to replace motherboard, do motherboard upgrades, troubleshoot motherboard, or build your own computer.

1. PCI Slot - This board has 2 PCI slots. These can be used for components such as Ethernet cards, sound cards, and modems.
2. PCI-E 16x Slot - There are 2 of them on this motherboard diagram, both are blue. These are used for your graphics card. With two of them onboard, you can run 2 graphics cards in SLI. You would only need this if you are a gamer, or working with high end video / graphics editing. These are the 16x speed versions, which are currently the fastest.
3. PCI-E 1x Slot - Single slot - In the PCIe 1.x generation, each lane (1x) carries 250 MB/s compared to 133 MB/s for the PCI slots. These can be used for expansion cards such as Sound Cards, or Ethernet Cards.
4. Northbridge - This is the Northbridge for this motherboard. This allows communication between the CPU and the system memory and PCI-E slots.
5. ATX 12V 2X and 4 Pin Power Connection Power Connection - This is one of two power connections that supply power to the motherboard. This connection will come from your Power Supply.
6. CPU-Fan Connection - This is where your CPU fan will connect. Using this connection over one from your power supply will allow the motherboard to control the speed of your fan, based on the CPU temperature.
7. Socket - This is where your CPU will plug in. The orange bracket that is surrounding it is used for high end heat sinks. It helps to support the weight of the heat sink.
8. Memory Slots - These are the slots for your RAM. Most boards will have 4 slots, but some will only have 2. The color coding you see on the motherboard diagram is used to match up RAM for Dual-Channel. Using them this way will give your memory a speed boost.
9. ATX Power Connector - This is the second of two power connections. This is the main power connection for the motherboard, and comes from the Power Supply.
10. IDE Connection - The IDE (Integrated Drive Electronics) is the connection for your hard drive or CD / DVD drive. Most drives today come with SATA connections, so you may not use this.
11. Southbridge - This is the controller for components such as the PCI slots, onboard audio, and USB connections.
12. SATA Connections - These are 4 of the 6 SATA connections on the motherboard. These will be used for hard drives, and CD / DVD drives.
13. Front Panel Connections - this is where you will hook in the connections from your case. These are mostly the different lights on your case, such as power on, hard drive activity etc.
14. FDD Connection - The FDD is the Floppy Disk controller. If you have a floppy disk drive in your computer, this is where you will hook it up.
15. External USB Connections - This is where you will plug in external USB connections for your case or USB bracket.
16. CMOS battery - This is the motherboard's battery. This is used to allow the CMOS to keep its settings.

So you've checked the supply, but you didn't replace it, right? Sounds to me like that's your culprit. It's not able to supply the current to run the processor (the biggest draw) and the output is dropping too low to run the system. A new supply should get you running again.

1. Could be as simple as not having the Power Switch on the right jumper...double check.
2. The board will power up with nothing hooked to it... just power, CPU, MEM... disconect everything to just to get the board up to the bios.
3. Make sure PS is securly connected to the MB.
4. Check Jumper on the Board to make sure the Test Jumpers are not set
5. Memory is seated correctly... if you pull them out the board will start and beep...

As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

ASUS A7V8X-X Motherboard

what is your problem? the wires go up and go on 2 wires sticking up they should have something below them that match, you may not need all of them hooked up. the power you need, tri hooking them up and turn the computer off and on each time till you find out where the go.
