Solved: Power On Pins On Power Connector

Generated Tue, 07 Mar 2017 11:56:07 GMT by s_bd41 (squid/3.5.23) 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 You must plug a cable into this motherboard connector or the CPU will receive no power. You can get adapters which will convert various kinds of power supply cables into both 4 pin and 8 pin 12V cables. Source

Nowadays things are a bit more complicated. But what happens if they don't match? The aux power cable A cable you're not likely to run into is the 6 pin aux connector. An error (403 Forbidden) has occurred in response to this request. have a peek here

If they don't fit together then you can get an adapter cable which converts a 24 pin power cable into a 20 pin cable. 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). 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

Since the Athlon 64 and Pentium 4, computers have consumed most of their power from the 12 volt rail. 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 Please try the request again. Almost all current motherboards power their CPU with a 12 volt CPU power cable.

If the motherboard requires this connector then you have to get a power supply which provides one. But these issues are listed for the thorough types out there (you know who you are). If you're buying a new power supply then try to get one with a 20+4 power cable. useful source 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 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. If you know that the power supply won't be used in an older computer then you can use an ATX12V 2.0 or newer power supply which delivers the bulk of its The 12V CPU power cables CPUs used to be powered by the 20 pin main power cable. Even if the connectors do match you can still run into trouble even though the power supply appears to have sufficient wattage.

If the motherboard draws too much current then it will overheat the connector which can burn or melt it. http://www.tomshardware.com/answers/id-3120593/pin-cpu-power-connector.html The system returned: (22) Invalid argument The remote host or network may be down. At least they did if the power supply delivered enough wattage. As a result, you need to be careful when plugging an old power supply into a new computer or a new supply into an old computer.

Those extra 4 pins provide more current carrying capacity. this contact form 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. If you had an ATX power supply and an ATX motherboard then you plugged them together and they worked. You can always plug a 20 pin power cable into a 24 pin motherboard but whether it works over the long haul depends on how much current your motherboard draws.

There are two kinds: the 4 pin 12V cable and the 8 pin 12V cable. It will work fine if it fits. The compatibility rules between 4 and 8 pin connectors have a lot in common with the rules for 20 and 24 pin connectors. have a peek here This kind of power cable is fully compatible with both 20 and 24 pin motherboards.

Where's most of the load? 3.3/5 volts or 12 volts?

Many newer power supplies come with a 20+4 power cable which has a 24 pin connector which can be split into two pieces: a 20 pin piece, and a 4 pin How a computer uses power has gone through a lot of changes over the years. Your cache administrator is webmaster. An error (403 Forbidden) has occurred in response to this request.

An error (403 Forbidden) has occurred in response to this request. 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 Most of the things mentioned here are either more detail than you need to know or problems which rarely crop up. http://bornsunsoft.com/solved-power/solved-power-strike.html 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.

An error (403 Forbidden) has occurred in response to this request. Those are the best supplies because they provide enough wattage for all kinds of machines. Sometimes they have three or even four 12 volt rails. 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.

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. If you've been researching power supplies then you've probably noticed that newer ones usually come with dual 12 volt rails. Back then ATX life was simple. If you're buying a new power supply then the safest choice for the long haul is to get one with a 4+4 power cable because it's compatible with both 4 and

Some older AMD dual CPU motherboards have them. The 24 pin cable is just the 20 pin cable with 4 extra wires added to the end to provide extra current. 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. 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

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. You can even get into trouble if you draw too little wattage. 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 The green links provide more detailed information on the subject.

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. An error (403 Forbidden) has occurred in response to this request. There are adapters which convert 20 pin cables into 24 pin cables but they don't solve the problem and can cause problems of their own. This subject of multiple 12 volt rails is more complicated then you may think.
