What is an eps12v? ATX12V 4-pin power connector also called the P4 power connector. A second connector that goes to the motherboard in addition to the main pin connector to supply dedicated power for the processor. For high-end motherboards and processors, more power is required, therefore EPS12V has an 8-pin connector. See Full Answer. What is a Molex cable used for? As SATA becomes more prevalent, Molex connectors can be found repurposed, through use of an adaptor, to serve as six-pin PCIe power connectors to make up for a lack of such connectors on a power supply.

Lower power devices e. Buying a fan controller will give you additional fan headers. MOLEX connectors are keyed as well. MOLEX fan connectors are older and don't offer any controls for the fanbut they're easy to connect. Molex is the name of the company who develops computer and other related connectors and products.

EPS12V - EATX12V 8 pin

This term is also known as the Molex power connector, which is the connector shown in the picture and is what connects your computer power supply to drives and devices inside the computer. SATA is most commonly used in nearly all computers today, due to below advantages. What are peripheral cables used for? The four pin peripheral power cable dates back to the original PC. It was used for floppy drives and hard disks. It's still around and is now also used for all kinds of things including add-on fans, extra video card power, supplemental motherboard power, and case lighting.

This cable is commonly called the 4 pin molex power cablebut this can be confused with the 4 pin main power cable which is a molex cable too. ATX 20 pin main power cable. In PC makers started switching to the ATX standard which defined a new 20 pin motherboard power connector. It includes a 3. What is an ATX power connector for? It is one of the largest connectors inside a computer. It connects a power supply to an ATX style motherboard. As shown to the picture to the right, this pin cable is a multi-color cable and may be labeled as P1.

PC cases themselves are often referred to by these three form factors, but the terms more accurately refer to the size of the motherboards they can host. ATX boards measure 12 by 9. Definition of: EATX. Connects to the motherboard EPS 12V socket. Provides additional power to the CPU. What is an EPS connector used for? What is the RAM and what does it do? Random Access Memory, or RAM pronounced as rammis the physical hardware inside a computer that temporarily stores data, serving as the computer's "working" memory.

Additional RAM allows a computer to work with more information at the same time, which usually has a dramatic effect on total system performance. What is PSU university? The Pennsylvania State University commonly referred to as Penn State or PSU is a state-related, land-grant, doctoral university with campuses and facilities throughout Pennsylvania. Founded inthe university has a stated threefold mission of teaching, research, and public service.

You shouldn't be able to switch between them - the square and rounded off connectors are arranged such that you can't.

The power connectors are different - while they're both 12V yellow and ground black the row closer to the clip of the PCIe connector is ground, and the bottom is 12V, and its the other way around on the EPS 12V. Attempting to switch between them will result in physical damage, from attempting to fit physically different connectors and electrical damage, from reversing the power feeds to the device.

Connectors themselves however are not typically colour coded in any way. In fact it is the cable itself that swap 12V pins and GND pins to comply with the mother board pin arrangement. Some cables come in all black, especially those come with power supply for cosmetic and some in all yellow anyway, you can't actually rely on the color. Sign up to join this community.

I'd examine the plug and socket, and the pci-e cable is usually labelled. More often than not 'cheaper' PSUs use that semi translucent white plastic, and 'premium' parts use black plastic in my experience.

Dbugger Indeed, all connectors are usually the same color in a given PSU. The reason for the difference is that EPS12V is an extension of a four-pin connector, while 8-pin PCIe is an extension of a six-pin connector.AXi PSUs still use what's called a "resonant mode" topology like a lot of modern day super-efficient power supplies, but typically in other resonant mode PSUs a PWM controller IC changes the power supply's switching frequency based on an analog signal derived from the load measured at the transformer.

This makes the power supply more efficient at a wider range of loads compared to other power supply topologies, but doing this alone can affect ripple and noise and voltage regulation. The resonant mode controller, shown above, is just about the only IC you'll find in an AXi power supply that you may also see in other high end power supplies.

The supervisor IC is the heart of the power supply's safety functions. Functions like OCP over current protection, which is protection from any one output drawing too much currentOPP over-power protection, which prevents overloadingOVP over-voltage protection, which measures if voltage goes too highUVP under-voltage protectionand SCP short circuit protection.

Temperatures are also measured within the power supply and this is reported to the IC's OTP over-temperature protection. If any value programmed into the IC is exceeded, the IC is instructed to shut down the power supply.

In an effort to improve voltage regulation drops in voltage as loads increasethe information concerning the power supply's output voltage is sent back to the PWM controller via an analog signal. This information moves relatively slow when compared to the ever-varying loads of your typical PC, so voltage regulation is still not as good as it can be. Above we see two more ICs found inside an AXi series power supply. These guys handle what goes on on the secondary side of the power supply.

The MCU I does what we call "housekeeping". This chip also handles the PMBus power management bus and thermal monitoring and fan control. On top of all of this, the MCU I also monitors the DC output for voltage drop, ripple and noise and communicates back to the DSP to address any issues that may come up. The self test function is also controlled by this chip.

Since the DSP accumulates all of this information about the power supply, and does so in real time, we can deliver it to the end user via our Corsair Link software. Power supplies have attempted to deliver similar information about the power supply to the end user in the past; either via software or displayed on a 5.

This adds a good deal of cost and prevents the information from being delivered as close to real time as possible. Using Corsair Link, we can monitor everything from AC input voltage, output wattage We can also keep track of the temperature inside the power supply and how fast the fan is spinning: All in all, AXi Digital Power Supplies are so much more than your average desktop PSU on so many levels.

By utilizing a DSP, Corsair offers improved efficiency while maintaining stable voltage output and minimizing unwanted ripple and noise.These power supplies will still function with older ATX systems using the pin main power connector, provided there is sufficient space.

Information in this article applies broadly to different types of power supplies. Make sure a power supply is compatible with your computer before making a purchase. Desktop specification standards were created to define the various dimensions, layouts, and electrical requirements so that parts can be exchanged between vendors and systems.

As power requirements and layouts changed, the industry developed a new definition called Advanced Technology Extended ATX in All computer systems require a power supply capable of converting electrical power from high voltage wall outlets to the low voltage currents used by the system components.

Part of the purpose of having specification standards is ensuring backward compatibility, so power supplies that are ATX12V compliant will usually work with ATX systems, but older ATX components do not work with newer machines.

The differences between the current ATX12V 2. Your motherboard will be the biggest decider on which power supply to use. Make sure you check to see if you have a pin or pin connector on the motherboard.

If you're not sure, always check with the manufacturer of your motherboard for proper power needs. PCI Express has a watt power requirement, which was not possible with the older pin connector, so four additional pins were added to supply the additional power through 12V rails.

Older ATX v1. The pin layout on ATX12V is keyed such that the pin power connector can actually be used on older ATX motherboards with the pin connector. The caveat is that the four extra pins will reside off to the side of the power connector on the motherboard, so be sure there is enough clearance for the extra pins if you plan on using an ATX12V unit with an older ATX motherboard. As the power demands for processors, drives, and fans keep growing, the amount of power supplied over the 12V rails from the power supply has also grown.

In order to address this, the ATX12V standard now requires the 12V rail to be split into two separate rails for any power supply that produces extremely high amperage. Some high wattage power supplies even have three independent 12V rails for increased stability. ATX power supplies normally only use a single rail at 3. Some increased power demands required some additional power.

You may find some ATX power supplies with an additional rail to provide that additional power. When the electrical current is converted from the wall outlet voltage to the lower voltage levels needed for the computer components, there is bound to be some waste that gets transferred into heat.

So, even though a power supply may provide W of power, it is actually pulling more current from the wall. The power efficiency rating determines how much power is pulled from the wall compared to the output to the computer. Using a higher efficiency power supply for your PC can lower your power bill. As manufacturers have all but stopped production, if you have an older motherboard, you'll have to rely on the ATX12V's backward compatibility to keep older PC's running.

Find More Posts by green granite. Thanks, green granite, but I have the manual along with the words you quote, and this is part of the confusion.

The mobo userguide doesn't help as it only shows pictures of connectors - both 4 and 8 pin - connected to the 8-pin socket, and makes no mention of nomenclature. All you can do is check that the volts on the pins are the same, or not and then make your mind up from that. Thanks again.

Either the one that is different is the 8 pin PCI-Express. You're over thinking this.

But that pin is a D instead of a square, so it'll fit D's can fit in square holes. If there was a "risk" of frying anything, they would have made the connections not interchangable. If you look at the wiring, you'll see they're the same three 12V power adapter and three ground. Originally Posted by Merpower. Page 1 of 2 1 2 Last Jump to page:. Replies: 1 Last Post:PM.
