How to Install Power Supply to a Motherboard

Video Transcript

Hi! My name is Stephanie and I’m here on behalf of expertvillage.com. Please visit our web site at www.clickincomputer.com. Now will be a good time to install the power supply. It can only fit one way into the case, but as you can see, this case already had a power supply in it, so we’re just going to go ahead and start plugging the power into the motherboard. Next what we’re going to do is install a 20-pin power connector into our motherboard. This particular power supply has this 24-pin connection as we were talking about earlier, so what we do is just break it off, then we plug it into the motherboard. It can only fit one direction. If it doesn’t fit one direction, turn at the other and it will snap down. The next thing that we’re going to plug in is the 12-volt connection for the Pentium 4, all our motherboards have this that your computer is not going to work without it. Next thing we’re going to plug in is the power for the CD-ROM. Again, it’s a four-pin Molex connector and it only fits one direction. Next is the floppy power, another four-pin, but smaller and then the serial ATA power. Serial ATA drive may have a plug for both the power that shaped like this and the power that shape like this, you can only plug one in, otherwise it won’t work. Simply snap it in and we’re done plugging in our devices.
