Some people like to have multiple USB port options for connectivity, while some prefer multiple graphics cards for extensive gaming.

In this overview article, we have discussed why VRM is the most crucial component, how it works, and why people should not overlook it when choosing a new motherboard. Just like the main power supply SMPS or switched-mode power supply takes or volts from the wall socket and steps it down to DC 12 volts, the motherboard VRM does this second time to provide appropriate voltage to CPU.

Most VRMs provide load between 0. Modern VRMs sense the [varying] required voltage from a processor and adjust the power supply accordingly. Such VRMs get really hot while doing their task, so they require a heat sink to dissipate excess heat. The VRM is usually implemented as a switching regulator due to its efficiency. Although it is just a buck converter that precisely steps down voltages to appropriate levels, its design is quite complex than a simple circuit.

Single-phase VRM circuit.

If the high-side MOSFET remains closed for a sufficient time, the inductor accumulates the full charge, reaching 12 volts same as the power supply.

However, the actual purpose of the inductor in a VRM circuit is to keep the voltage from instantly reaching 12 volts. A large inductor, for example, with a high inductance will change the voltage at a relatively slower rate. At the same time, a sudden voltage spike is generated across the inductive load. To eliminate this spike, a flyback diode is connected across the inductor. The aim of the circuit is to deliver the appropriate voltage required by the CPU. Since most modern microprocessors consume 1.

As soon as this happens, the voltage starts dropping. After a certain voltage drop, the circuit again starts charging up the indicator. This cycle is repeated again and again via a method called pulse-width modulation. So 25 amperes is transmitted through the first phase, and the other 25 amperes is transmitted through the second phase.

VRM four-phase diagram. The more power phases you have, the more reliable the VRM is. In particular, the more power phases you add, the cooler each phase runs, and the more power VRM can put out, providing more stable voltages to the microprocessor. Better stability of power for the processor can also reduce the required voltage for overclocking stability to some extent. It is important to understand that the quality of VRM cannot be improved by just adding more power phases.

The actual components and their circuit integration play a major role in determining how much power the VRM can handle and for how long it can output stable voltage. It can also result in unexpected shutdowns, especially when overclocking. VRM components on the motherboard. But since RAM consumes much less power than the processor and only a few people do RAM overclocking, it is often ignored.

Most VRMs do not produce a fixed voltage. Instead, they get digital signals from the microprocessor, which instruct them about required varying voltage levels. At startup, VRM provides a predefined voltage to the microprocessor. Once VRM receives the VID, it decodes the needed supply voltage and starts operating as a voltage regulator, continuously providing the required power to the microprocessor.

It also minimizes power consumption during ideal intervals by reducing the supply voltage. For instance, a unit with 6-bit VID outputs one of 64 2 6 distinct output voltages.

These voltages are generally spaced within a specific range.Choosing the best motherboard for your PC is a critical part of the process. It's easy to make the wrong choice with a motherboard, which is why we rounded up some of the best motherboards right here to help you make the right choice.

Deciding on AMD or Intel for your processor or already having one inside a rig you plan to upgrade narrows the search for a new motherboard considerably. Intel motherboards come with Intel chipsets that only work with processors from the company, likewise with AMD.

Then you have specific chipsets from Intel and AMD that only work with certain processors. Intel's Z is good for 10th and 11th Gen processors. Take a gander at our full list of best motherboards to see which one best suits your PC build plan. It doesn't deliver all the features you'd find in enthusiast-grade boards, but this is about as good as you can get for a desktop motherboard.

The motherboard is super-important, but it's also challenging to get it wrong, so long as you buy one that matches the CPU you intend to install. This isn't the most capable AMD motherboard, but you likely won't require all the additional features that come with splashing out on the most premium motherboards around.

The AM4 platform is what has been used by AMD since Ryzen launched inand the X is the latest high-end chipset from the company.

B550I AORUS PRO AX (rev. 1.0)

This platform will support not only Ryzen processors that are out now but also series set to launch sometime in the future. It's possible to install up to a maximum of GB RAMusing the four DIMM slots provided, though the likelihood of you requiring any more than 32GB is a stretch since only intensive workstations that handle huge files video editing, for instance need such large amounts.

This is one of the more critical factors of choosing a motherboard, as well as a solid power delivery setup. Capacitors and other performance components should be part of a premium batch for enhanced reliability and better support for overclocking.

The rear port selection is pretty good for too. You can easily hook up all your favorite gaming accessories and then some. You've also got RGB connectors, pump headers for water-cooling, two M. It's not a budget motherboard, but you do get a lot for the money here. You can install plenty of RAM and take advantage of the excellent stability and build quality. When looking at a motherboard to purchase, you'll want to consider a few factors.

The first is which platform do you intend to use: Intel or AMD? Next is the chipset. These determine the features and pricing the motherboard can have, with the X and Z being the best choice for AMD and Intel, respectively. More budget-friendly chipsets like the B offer incredible value. Speaking of value, price is a consideration worth making. It's recommended you spend a fair amount on a motherboard. You want to make sure you're getting high-quality components and decent cooling for the voltage regulator modules VRMwhich can get incredibly hot during operation, especially if you plan to push the system further through overclocking.

Components like the VRMs come in all shapes and sizes, and it's down to the vendor to pick high-quality electronics for a more stable motherboard. The processor you plan on using can also be of importance. Our enthusiast pick will be overkill for an AMD Ryzen 3for instance.

On the flip side, you wouldn't want to install an AMD Ryzen 9 X on a B budget-friendly motherboard, since this would prevent you from overclocking the CPU, and the system may encounter stability issues with other components, like activating an XMP profile for RAM. Motherboards can remain relevant for as long as your processor can keep up with what you require it to do.So today, we will introduce the concept of the VRM and these so-called power phases as simple and straightforward as possible, so that you can easily discern what a motherboard product page is telling you and when it matters.

The transistors may or may not be covered by a heatsink, as they can get very hot and tend to be more temperature-sensitive. The chokes on modern motherboards usually appear as small black or grey cubes, which sometimes have a small differently-colored section in the middle. The capacitors are the other component, usually small cylinders in shape, next to the chokes. Photo by Dsimic. There are two separate groups of power phases in the VRM. Cooler operation improves lifespan of the VRM and reduces the risk of overheating, a potential concern for overclockers.

A higher power output ability reduces the risk of overloading the VRM, which could make the system shut down or slow down the CPU. Better stability of power for the CPU can, to a limited extent, reduce the needed voltage for overclocking stability, improving CPU temperatures and theoretical lifespan. It is important to understand that more power phases does not necessarily mean a better VRM.

The actual component choices in the whole VRM have big implications in running temperatures and how much power the VRM is capable of handling. Four phases could very well be an overall better choice than eight phases if the components are sufficiently better. A fairly common design used by motherboard manufacturers is to double the amount of components used in each power phase, without actually doubling the number of power phases.

In addition, and arguably more importantly, motherboard manufacturers often but not always use this design while also claiming a higher phase count. This practice is misleading and not ideal compared to more actual phases, but it does still help.

Even worse than this, motherboard manufacturers occasionally go beyond marketing doubled-component phases as more phases—by not even doubling all of the components, while still claiming a higher phase count. Doing this makes any lies about phase count even more egregious, and to a limited but not large extent reduces the actual benefit. The only way to really know the phase count is through analyzing the actual components or, more accessibly, through seeking out a knowledgeable video-maker or writer online who has done this sort of analysis on the board or boards you are considering.

Ultimately, on systems with recent-generation CPUs, worrying about the VRM will mostly be relevant for those who want to achieve high overclocks, and not for typical users.

Temperatures can always be a concern, but actual temperatures will always vary between users and their hardware, while any effect on motherboard lifespan is unclear. But by knowing this, you can make your choice more effectively for your needs. Share This Post:.Some voltage regulator modules are soldered onto the motherboardwhile others are installed in an open slot designed especially to accept modular voltage regulators.

Some processors, such as Intel Haswell CPUs, feature voltage regulation components on the same package or die as the CPU, instead of having a VRM as part of the motherboard; such a design brings certain levels of simplification to complex voltage regulation involving numerous CPU supply voltages and dynamic powering up and down of various areas of a CPU.

Most modern CPUs require less than 1. Some voltage regulators provide a fixed supply voltage to the processor, but most of them sense the required supply voltage from the processor, essentially acting as a continuously-variable adjustable regulator. In particular, VRMs that are soldered to the motherboard are supposed to do the sensing, according to the Intel specification.

The correct supply voltage is communicated by the microprocessor to the VRM at startup via a number of bits called VID voltage identification definition.

When the VRM has received the VID identifying the required supply voltage, it starts acting as a voltage regulatorproviding the required constant voltage supply to the processor. Instead of having a power supply unit generate some fixed voltage, the CPU uses a small set of digital signals, the VID lines, to instruct an on-board power converter of the desired voltage level. The switch-mode buck converter then adjusts its output accordingly. The flexibility so obtained makes it possible to use the same power supply unit for CPUs with different nominal supply voltages and to reduce power consumption during idle periods by lowering the supply voltage.

For example, a unit with 5-bit VID would output one of at most 32 2 5 distinct output voltages. These voltages are usually but not always evenly spaced within a given range.

Some of the code words may be reserved for special functions such as shutting down the unit, hence a 5-bit VID unit may have fewer than 32 output voltage levels. How the numerical codes map to supply voltages is typically specified in tables provided by component manufacturers. Since VID comes in 5- 6- and 8-bit varieties and is mostly applied to power modules outputting between 0. From Wikipedia, the free encyclopedia. A Basic Definition".

Tom's Hardware. Retrieved 7 November Retrieved John Seago.Did we just confuse you even more? We all know that your PC runs on classic power supplies, and some of you probably know that they can produce only three constant voltages which are 3.

So, if a CPU or GPU need something around 1V, you can see the problem that we are facing — higher voltages need to be converted to lower voltages.

The part that does the converting is called the DC-DC converter, and unsurprisingly, it converts direct current to another direct current. To be a bit more specific, a higher voltage needs to be converted to a lower value, and the DC-DC converter we are interested in, is called a step-down buck converter.

As always, we are going to be brief and blunt with our explanation. Almost every higher end motherboard has an elongated heat sink near the CPU socket. Why do we need to cool these parts, what is the benefit of it?

So, if you want to work in a stable environment, have a safe overclock or just want to prolong the life of your hardware, you need to keep that VRM cool! The VRM is a sort of DC-DC converter which is composed out of three main parts: the logical unit, the power unit, and the filtering section.

The logical unit is made up of one rarely more than one chip that is called the voltage controller or the PWM chip, or the Pulse Width Modulator. The role of the PWM chip is to govern the drivers and doublers if they are present. The final section of the VRM is where the filtering and voltage smoothing is done. This is happening through inductors, that are popularly called chokes, and capacitors. The quality of the motherboard is often expressed by how many VRM phases it has.

This is a block diagram of a VRM that has eight true phases and the dashed line marks what is supposed to be one individual phase. Usually, by counting the number of inductors chokesyou can determine how many phases VRM has. The number and type of capacitors does not follow any rule and is set by the manufacturer. Some high-end solutions even implement different types of capacitors to filter the power that is delivered to the CPU. The important bit that you need to know, is that the voltage conversion starts at the MOSFET and it is handling the biggest workload.

Classic air cooling is often trying to cool the key components, but mostly it just recirculates hot air inside the computer case. Liquid cooling on the other hand, transfers the heat away and dissipates it through the radiator. You can see the current selection of the EK Monoblocks here.

On the other hand, if a stock cooler is replaced with liquid cooling, it could ensure a longer life for your hardware. Until next time, stay cool! Read more. Join the EKWB forum, talk to our team, share your thoughts and connect with the liquid cooling community. English Slovenian.A low-quality VRM can cause many issues including shutdowns under load, poor overclocking capability, and even reduce the life-cycle of your processor.

A modern PSU supplies 12 volts of power to the motherboard and graphics card. It steps down the incoming volt power supply to 1. How it does that is the interesting part:. It basically dictates how many true phases can you implement in a VRM without using doublers. The former is connected to the ground while the latter is actually what conducts the power to the inductors.

As you may have already read, only one phase is active at a time. The second phase takes over and the Low-FET of the first one is turned on which is connected to the ground. The frequency here refers to the speed at which the various phases switch between one another. Finally, you have the capacitors that store the current received from the inductors in the form of an electric field and supply it to the CPU as and when needed. These are also connected to the ground to dispose of any excess current.

Capacitors basically are present to iron out any ripples and spikes that may occur due to the ripple frequency or simply due to the switching nature of the MOSFETs. They also regulate the power supplied to the CPU as per the need by storing appropriate amounts while disposing of the excess via the ground connection. Every VRM will consist of these three components, regardless of the motherboard or graphics card.

These are more efficient and reliable than single-phase VRMs. They function by distributing the supplied power among themselves, reducing the load on the individual components as well as the heat produced. This not only improves the heat dissipation and efficiency but also helps power processors with higher TDPs safely. Another important advantage of multi-phase VRAM is that it helps reduce the ripple current. The lower the ripple frequency, the better. Using multiple phases significantly reduces this:.
