motherboard VRM

[MightyNerdy9]

hey guys , i wanna choose a motherboard , i know about the size , number of m2 slots , chipset ofc and number of type-c 

 

but i have 2 questions that i dont know how to answer : 

 

1. what is exactly vrm ? how do you identify a good mobo vrm ? what is vrm used and important for ?

2. usb-c , on header and front , what are those ?

VRM is Voltage Regulator Module, it handles how power is delivered to the CPU in layman's terms.

 

Motherboards list their VRM on the spec sheet.  I personally don't know, without being told by someone else, how to compare VRMs with CPU needs.

 

I just read reviews     You'll pick up over time what is a good power delivery for each generation of CPU.

Hardware unboxed MB reviews go in detail about VRM

 

As a rule of thumb, a better VRM has:

-Many VRM

- complete heatsink

- capacitors NOT zigg-zagged (I don't know why, but bad VRM need more smoothing by capacitors and that requires the zig-zag layout)

 

But to go in detail, look at HUB reviews. They show the VRM temps and tell the cutoff which to avoid.

 

And the type of CPU also matters. A 6 core can get by with a worse VRM than a 16-core. And case ventilation also matters.
