The quality of the motherboard is often expressed by how many VRM phases it has. A set of drivers, MOSFETs, chokes and capacitors make up a phase of the VRM. This is happening through inductors, that are popularly called chokes, and capacitors. The final section of the VRM is where the filtering and voltage smoothing is done. The drivers and doublers are connected to the MOSFETs and they are all part of the power unit. The role of the PWM chip is to govern the drivers and doublers (if they are present). 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. 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.Įxample of 8 phase VRM on an X99 based motherboard. The high workload on the CPU or GPU and overclocking, makes the MOSFET in the VRM hot. ![]() The efficiency of a MOSFET is always presented by a curve which depends on the amount of current passed through and of course the quality of the MOSFET itself.Įfficiency graph of a MOSFET used on the Gigabyte Z97X-SOC Force motherboard. All electrical loss is converted to heat, and the heat generated by the whole VRM can almost directly be linked to the efficiency of the MOSFETs being utilized. Why do we need to cool these parts, what is the benefit of it? MOSFETs have an efficiency factor and they pass through high currents. Peak temperatures can range from 80☌ to 100☌ and in cases of high-end graphic cards, temperatures can be even more extreme, up to 120☌. This is for cooling the VRM section, or to be more specific, to cool MOSFETs themselves, which tend to get really hot. Almost every higher end motherboard has an elongated heat sink near the CPU socket. 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.Īs always, we are going to be brief and blunt with our explanation. The part that does the converting is called the DC-DC converter, and unsurprisingly, it converts direct current to another direct current. 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 important bits in a computer, like the CPU and GPU, usually have the operating voltage between 0.5 and 1.5 volts. 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 3.3V, 5V and 12V. VRM, or Voltage Regulator Module, as its name would suggest, is the part that regulates the voltage for the most important components, such as CPUs and GPUs. Did we just confuse you even more? OK, let’s fix that. MOSFETs are small electrical components that, with other components, make up the VRM.

Thor doesn't have the striking feats to show he hits harder. Hulk is BFRed almost instantly so who hits harder or is more durable between them is moot here. Iron Man isn't a factor here regardless of who takes him out. I believe Barry phased through a truck and Thawne is his superior at just about everything. He can definitely hurt Iron Man through phasing. Quicksilver is a good fight for Flash but he's out of his league with Thawne. He was fast enough to be in 2 places at once. If his goal was to murder people, people would be murdered. ![]() Both Thor and Hulk are more durable and hit harder than Clark, they'd overwhelm him. ![]() ![]() Superman taking them both individually is debatable, him vs both at the same time is too much. Even if it comes down to Supes vs Thor and Hulk, he can't take both of them. Furthermore, he cant harm Iron Man only maybe with phasing (even though he's never phased through anything with significant density) but he has to hold still to do that and when he does he's dead. He murders everyone like he did those bunch of street levelers he fought? Plus he isn't that significantly faster than Quicksilver who could keep Thawne busy long enough for Wanda to TP him and Supes. Thawne murders everyone except Hulk and Thor and Supe can handle them.
