You may have to unscrew the first two top brackets first-
Keep the equipment stable--
Then twist the bottom hole.

It takes great patience and flexibility to learn how to install computer components. 3.
Set the voltage switch to plug the power into the heart of your mother who has traveled abroad, and you may realize that sockets in some countries use 220 v. -
So are their computers.
For this reason, the power supply comes with a voltage switch.
Find it on the back of the power supply.
It\'s probably pink. colored switch--
There is a reason why it stands out.

If so, OK, make sure before you go ahead.
Otherwise you will have a serious problem.
Next, you plug the power into the motherboard.
Look for leads from the power supply connected to the motherboard.
The most common of them is the ATX connector;
These are standard 20-pin cables.
If you have an updated Pentium 4 computer, you may also need to connect the 12v 4-pin connector to the motherboard. 4.
If you choose to install computer power devices without connecting them to any internal device of your computer, it will be useless to connect the power to the internal device.
Your power supply actually powers several devices in your computer.
You\'ll notice that there seems to be a lot of loose cables on your power supply, looking for a plug that plugs somewhere.
The most common destination for these hanging lines is your optical drive--
Your CD and/or DVD-ROM drives.

Turn off the system and plug it in and you\'re almost done.
Check the connection between the power supply and the equipment to which it will be powered.

Conclusion in this tutorial you have learned how to install a computer device like a power supply, which is something you can be proud!
It may be a challenge for beginners to know how to install a desktop power supply, but we believe we have simplified the installation for you.
This requires a little mechanical skill and patience.
But in the end, learn how to do-it-
You yourself are much cheaper than paying someone else.
This is also a more gratifying thing.
Also, we believe that you can learn how to replace the old power supply if you need it.
