Direct 6+2+1 Phases Digital VRM Solution

Will this motherboard be strong enough on the power section to fully support this processor?

No you really want an X890 board for those CPUs

It should be fine for the 9800X3D, I don't know why people think they need a super high end motherboard for an 8 core CPU, affordable motherboards have been easily capable of driving Ryzen 7s since B550

[_I_]

6+2+1, means 6 to cpu cores, +2 to igpu, +1 to imc

each phase is around 25w if it has a heatsink, or 20w without cooling
6x 25 = 150w to cpu cores, not enough for a high or even mid range ryzen cpu

its a 125w cpu, but it can reach over 2x what amd or intel say

get a board that has 10+ phases to cpu coes +1 or more to cpu an igpu
14 or more total, on boards that do not say, count the choke coils (black bricks near the cpu socket, then subtract 2-4 for imc/igpu)

It's 6 phases each rated for 60A, so in theory the total of what those phases can handle together is 360A which is more than enough for a 9800X3D, and there are users of that board with Ryzen 9 that have no reported issues with performance and they've tuned their CPUs as well.

The problem with the B650M GAMING X AX is the fact that it's surrounded by motherboards with even more monstrous VRM options in the same price point, where it sits in price doesn't make a whole lot of sense.

It's also on the high end of VRM thermals with a 7950X, but I don't think that's an issue because it's a much higher power chip, 9800X3D sips power in comparison. CPU power consumption while gaming would rarely exceed 100W at stock config.

mosfets have not gotten that much better in the last 20 years

and its more of a limit to the choke coils that are used to even out current draw to regulate he voltage spikes the mosfets make

if the chokes would need to be much bigger to handle 60w ea
(~1v x 60a = 60w)

the low end boards are (3-4)+1+1phases for a 60w cpu
with that math they could do that with 1+1+1 config

Do you realize you are actually suggesting someone configure a computer in a dangerous way that has a high probability of resulting in damaged hardware? If anyone needed any further evidence that you have absolutely no idea what you're talking about in relation to computer hardware this is a perfect demonstration of that right here.

"Dangerous"

Literally nothing dangerous about it, the motherboard has been shown to work with more power hungry chips without issues, the person that doesn't know what they're talking about is you and you're just trying to bait people. Give up on your hopeless crusade.

You're telling people to install a CPU into a motherboard that can't handle it either thermally or power wise. Putting a 9800X3D in that motherboard is dangerous and would have a very high probability of resulting in damaged hardware. Either damaging the motherboard or damaging the CPU or both.

Someone has to say something this time. Your complete reckless abandon for other people's computer hardware is going to result in someone wasting a lot of money on hardware this time. This is just too far.

if you buy the highest end CPU for gaming then why are you cheapening out on the important part? might as well cheap out on the PSU as well

Because there is no meaningful performance difference between most AM5 motherboards. If someone doesn’t need USB4 ports or overkill VRM to overclock a 16 core 9950X, then the money would be better spent on a stronger GPU that does affect performance.

Actually there is a big difference. Many B650M cheaper AM5 motherboards have a locked and forced power limit programmed into their bios that the user can not adjust. Some B650M motherboards even limit processors to just 90 watts. This means that if someone installs a processor that needs more power then it will be limited artificially in lower-power-limit B650M motherboards. Sometimes as much as -30% or more of what it's capable of.

There can be potentially a big difference if the VRM is insufficient to drive a power hungry CPU. There are like 3 budget b650 motherboards on the market that struggle with 16cores 7950x/9950x in stress tests.

For a power efficient 9800x3D this VRM is plenty.

If there is a real life gaming performance difference between more expensive boards then I’m open to be proven wrong.

I paid for a more premium option to get extra features like error code display but I don’t hope for any more FPS in games.

Here is a good comparison of different motherboards.

If you're not going to educate yourself or take suggestion from those of us who actually know WTF we're talking about, why even ask then.

Just buy the CPU then, have fun with that.
Good luck having all sorts of power issues and never getting the full performance you paid for.

Cheap Motherboard is just as bad as a cheap PSU.

B650 should never be used for Ryzen 7 or 9 series; period.

What performance problems should I be worried about with my ASUS B650E-E that has bigger VRM than many (most?) X870 motherboards?

Why does Ryzen 7 need double chipset from X670 and X870 boards?

its not dangerous to put a power hungry cpu in a weak board that cannot give it the power it needs to run at full performance

the only boards that ti was 'dangerous' on were the msi am3/3+ that use dr-mosfets that did not have any thermal protection and would overheat an cook themselves
but the chances of fire outside the case/mobo were exactly zero
the only damage done is done to the mobo, none to cpu or other components

on all other boards, the mobo knows the limits and would force the cpu to throttle to stay within its power delivery spec even tho the cpu could demand much more
