How To Connect Power Supply To Motherboard


If you need a power supply for an older computer then you can use an ATX12V 1.3 or earlier power supply which provides most of its power on 3.3/5. The information below is just a summary.

Even if the connectors do match you can still run into trouble even though the power supply appears to have sufficient wattage. Older power supplies provided the bulk of their wattage on the 3.3/5 volt rail and new supplies deliver it on the 12 volt rail. As with plugging a 24 pin cable into a 20 pin motherboard connector, you can plug an 8 pin cable into a 4 pin connector and leave 4 pins hanging over The 24 pin cable is just the 20 pin cable with 4 extra wires added to the end to provide extra current.

How To Connect Power Supply To Motherboard

Nowadays things are a bit more complicated. Most current power supplies don't have aux cables and aux cable adapters apparently don't exist (unless you're good with a soldering iron and can build your own). But what happens if they don't match? You can plug a 4 pin 12V cable into an 8 pin motherboard and it will sometimes work properly but other times it won't work at all or will burn/melt the

EEEIS2015 provided an excellent international exchange platform for researchers to share their knowledge and results and to explore new areas of research and development.Global researchers and practitioners will find coverage of http://www.tomshardware.com/answers/id-1751830/motherboard-power-connections.html The proceedings can be a valuable reference work for researchers and graduate students working in rail transportation, electrical engineering and information technologies.

And if you have a multiple 12 volt rail power supply in a very high-powered computer then you may have to deal with rail balancing problems. Corsair If the motherboard draws too much current then it will overheat the connector which can burn or melt it. But these issues are listed for the thorough types out there (you know who you are). The motherboard main power cables The ATX standard has two different versions of the main power cable: the original 20 pin cable, and the the newer 24 pin cable.


All about the various PC power supply cables and connectors Rail complications #1 - current limit problems: too much current Rail complications #2 - cross loading problems: unbalanced current Rail complications http://www.tomshardware.com/answers/id-1669161/motherboard-problems.html An error (403 Forbidden) has occurred in response to this request. How To Connect Power Supply To Motherboard He has presided over more than 60 national, provincial and ministerial research projects in the field of electrical and information technologies for rail transportation, and he also has won 11 national Eatx12v How a computer uses power has gone through a lot of changes over the years.

Now you can get an ATX power supply and ATX motherboard and end up with connectors which don't match. http://bornsunsoft.com/power-supply/how-to-connect-molex-to-power-supply.html Back then ATX life was simple. Those are the best supplies because they provide enough wattage for all kinds of machines. If you plug a 24 pin power cable into a 20 pin motherboard then it will work fine but you often can't get them to physically fit together because something gets Computer Wont Turn On

Plugging a 20 pin cable into a 24 pin motherboard can strain the 20 pins that you're using. He is a chief scientist of State Key Lab of Rail Traffic Control and safety, and he serves as the Director of Traffic Intelligent Systems and Security Research Center, Vice Chairman This page introduces you to the issues you need to consider to maximize the chance that an ATX power supply and motherboard will work together properly. http://bornsunsoft.com/power-supply/power-supply-compatibility-with-motherboard.html You can get adapters which will convert various kinds of power supply cables into both 4 pin and 8 pin 12V cables.

The aux power cable A cable you're not likely to run into is the 6 pin aux connector. Newegg You can have cross loading problems with some power supplies if you draw unbalanced amounts of wattage from the 3.3/5 volt and 12 volt rails. The 12V CPU power cables CPUs used to be powered by the 20 pin main power cable.

Since the Athlon 64 and Pentium 4, computers have consumed most of their power from the 12 volt rail.

If your power supply main power cable and motherboard main power connector both have the same number of pins then they'll (of course) fit together just fine. Experts in these fields contributed to the collection of research results and development activities.This book will be a valuable reference for researchers working in the field of Electronics, Electrical Engineering and There are also many newer ATX12V 2.0 or newer power supplies which provide enough wattage on 12 volts for newer computers as well as enough wattage on 3.3/5 for older computers. This kind of power cable is fully compatible with both 20 and 24 pin motherboards.

Limin Jia, chief professor of Beijing Jiaotong University. The best choice is to plug a 4 pin cable into a 4 pin connector, an 8 pin cable into an 8 pin connector, or a 4+4 cable into either kind Older machines used to consume most of their power from the 3.3/5 volt rail. http://bornsunsoft.com/power-supply/connecting-power-supply-to-motherboard-guide.html At least they did if the power supply delivered enough wattage.

You can even get into trouble if you draw too little wattage. This subject of multiple 12 volt rails is more complicated then you may think. Where's most of the load? 3.3/5 volts or 12 volts? An error (403 Forbidden) has occurred in response to this request.

Power supply information Compatibility issues for ATX power supplies and motherboards A short history of PC power supply

The 4 pin cable is often called a P4 cable (although it's a very bad name) and the 8 pin cable is called an EPS12V cable. If you're buying a new power supply then try to get one with a 20+4 power cable. He has published 7 monographs, 5 College Books and 240 papers, and more than 130 papers have been indexed by SCI or EI.Bibliographic informationTitleProceedings of the 2015 International Conference on Electrical Some older AMD dual CPU motherboards have them.

You must plug a cable into this motherboard connector or the CPU will receive no power. VGA video card outputs Useful technical information How to install your motherboard chipset drivers Test your motherboard memory with Memtest86 Torture test your CPU with Prime95 How to find specifications for The green links provide more detailed information on the subject. Most of the things mentioned here are either more detail than you need to know or problems which rarely crop up.

Sometimes they have three or even four 12 volt rails.
