AMD, despite the latest successes in terms of sales and distribution on the processor side and even GPU, remains a "small" company compared to its rivals, so the releases of its products are often made in waves, with varying availability.

The Ryzen 3000 processors are an excellent product in many aspects, but until recently they were "limited" in their innovative charge by the high price of the matched X570 motherboards. There were only models from more than 300 € on the market. Furthermore, the X470 compatible cards on the market, required a bios update, so new systems had to be updated first using a processor from the previous series.

Finally now there are models from 200 € and less, and the usual doubt arrives: which one to choose? What criteria should I apply to select a motherboard? Our guide gives indications on what to evaluate, but here I want to go straight to the point for the new Ryzen.

When you spend around 200 € on a motherboard, you have all the features. It is difficult to find a manufacturer that offers you less USB sockets, or cuts chipset features or imposes strange limitations. So I think the focus should shift on quality of the electronic components used to manage the power delivery.

Inside the computers there are many states of energy transformation. The first is that of the power supply. His task is to transform the 220V alternating current from home into direct current at different voltages to supply the components correctly.
The power supply's 12V network is connected to the processor. This voltage is lowered to 1-1.5 volts required by the CPUs. The components that perform this task are called VRM.

These can be constructed in many different motions, but the basic concepts remain the same. More phases it is a voltage regulation system, the more the power is sorted on the various components and therefore everyone works with a lighter load. More commands PWM drive the various phases, the output voltage will be cleaner. Best is the heatsink, the more they will remain fresh and efficient.

In recent years there have been a couple of dusts around VRMs, mainly due to Intel and its poor management of the launch of the X299 platform. To make things fast, motherboard manufacturers used standard VRM solutions, none of which were really equipped to handle the enormous power required by intel overclocking processors, which were then limited because VRMs worked at very high temperatures and entered thermal protection.

In terms of Ryzen processors, we are on really low overclocking margins compared to what the processors can do, and the 7nm guarantee very low power consumption. So here is a great opportunity for motherboard manufacturers to save money on VRMs.

For AMD, once again, the best manufacturer proves to be Asus. Hardwareunboxed it is usual to do so many tests in this regard and in their analysis of the VRMs we can see how, equalizing the frequency and voltage applied to the processor, the Asus solution is the freshest of the X570 of the 200 € band. Which makes it preferable over the others if you decide to overclock your processor, ensuring greater efficiency in sustained workloads.
Not only that, this advantage also extends when you don't decide to overclock but rely on automatic turbo management.
