    I have already switch to a new PSU but the same problem happened. I don't understand why when I plugged the 20 pin ATX connector and the 4 pin ATX connector together, the CPU fan turn for a second and stop. When I unplug the 4 pin ATX connector, the CPU fan is turning.

Most motherboards now have a 24-pin power supply connector. If you haven't already found a diagram showing the pinouts of the 20- and 24-pin power plugs, here's one borrowed from a handy site:


The two plugs are essentially the same, but the 24-pin version duplicates some voltages on the extra pins. The extra pins in the larger connector were meant to provide extra current paths for voltages that see heavy loads from newer processors and motherboard circuitry. Depending on how a motherboard is designed, it might work with a 20-pin plug connected (leaving pins 11, 12, 23 and 24 empty). But typically if the board has a 24-pin connector it needs the 24-pin power supply plug.

Most power supplies have a 20-pin plug with a separate 4-pin section that fastens to it for connection to a 24-pin mobo connector. It typically has one side designed to slide onto the end of the 20-pin plug, essentially turning it into the 24-pin version. This added plug does not have a retaining clamp on its side, so you can tell it from the the 4-pin CPU power plug. The wire colors are also different. For reference, here is the processor power plug, from the same website:

New motherboard specs call for the separate processor power connector for the same reason the extra pins were added to the power supply connector: to handle the high currents needed by increasingly faster CPUs.

When the motherboard has these connectors, you need to use them all to get everything working. Hope this helps. Thanks to for the diagrams, and thank you for using Fixya.

System won't turn on but when i pushg down on one side of the power suply connectore the fan starts running but computer stioll won't turn on it used to boot up then opne day stopped

It sounds like you have a faulty connector - I would return the item under warranty. Otherwise, if it is out of warranty, you will have to source a new motherboard.

Motherboard power problem due to atx 12v cable

I tried different power supply but its still not powering up. But when i remove the 4 pin 12V cable from power supply the cpu fan is rolling, it means that the power supply is working but when i tried to connect the 4 pin then the cpu fan stop just a second and never rolled on. The main problem is the 4 pin, the model is Asus P5P800-VM. I tried to reset the cmos and replaced the battery but it wont work out. Please help me!!!

Some motherboard/cpu setups require an additional 4-pin connector for additional power on the motherboard. The motherboard will require either a 20-pin or a 24-pin power connector (main power), and might need the additional 4 pin as well. If the motherboard will accept the additional 4-pin, then connect it!

Since the only thing connected is the power suppy and the CPU, this is often caused by a power supply unable to provide the power to the MB. You will need to swap out the power supply and that should take care of the problem.
