Exclamation Removing your PSU


Note: Before starting, check wether your PC is using the ATX or ATX12 power supply, as the main connector to the board will be either 20pin or 24pin. You may also want to use some adequate anti-static protection such as an anti-static wristband. Remember to be careful!!

Ok, before you remove anything get a pen and a piece of paper and take note of all of your power connectors and where they are connected to.


-Take out the plug going from your mains power supply into the back of the PSU.

-Remove all of the 4-pin molex connectors from all of your drives (CDROM, DVD ROM, Hard drive, Floppy drive (this is a 4-pin mini-molex connector)).

-(refer to ATX connector.jpg). To remove the 20-pin main power supply connector you need to pinch the small tab circled, and it will come out with a little bit of a pull. If you have the small 12v 4-pin molex connected to the board then you need to do the same with this one as well (12V.jpg).

-Check for any power supply from your fan onto the motherboard and remove it. Along with any additional connections such as graphics card power supply.

-If you are just going to use your other PSU to test the motherboard it won't be necessary for you to completely remove the PSU from your PC tower. Although if you feel that this is necessary, then you should find about four screws on the back of your tower which are holding the PSU in. Carefully undo the screws and remove the PSU.

-Take your other PSU and put it in the space where you have just taken your old PSU from and replace the screws.

-Refer to the notes you took earlier and connect all the connectors to the appropriate slots either on the board or to the drives, make sure you are connecting them the right way round to avoid any damage.

-Check again to make sure everything is where it should be (especially the power for the fan because if you forget this one it will take about 60 seconds before your processor blows!, then connect the plug from the mains into the back of the PSU and turn on your PC.

P.S. If the PSU you are using to test your board isn't very powerful and it still doesn't seem to power up then just leave all the connections on the board and disconnect all your other drives except for the hard drive.

Regards

Martin
