OK, I will send you a private message.
why intel when amd is the market leader now
My application is not "audio." It is this piggy application Audio Precision ships to control the analyzer. On my core i5-7400 machine, it takes 5 to 6 seconds just to open the folder that has the test templates! Switching from one mode of the software to another takes another 4 to 5 seconds.I know it's from out of left field, but for variety and audio work these are cheap as heck right now and you can put 16GB and 2 2.5" SSD/HDD in them easily. You could then have OSX and Windows 10 (boot camp), and firewire support as well.
I must have watched 100 videos on this thing by now on everything from CPUs to GPUs to motherboard and VRMs.@amirm you should look at buildzoid in YT for VRM reviews and related things. If money isnt an issue just go with some asus, they are always pretty good but pricey so its a safe purchase

I should say though I don't find their VRM analysis informative at all. They just rattle off the chips used, phases and then make some random conclusion at the end. I don't get that any of them are electrical engineers and know how to test these things properly. Counting "amps" per phase and such is silly.
Usually people only care about VRMs to the extent of how many amps they can provide, to make sure they won't explode trying to power their CPU.I must have watched 100 videos on this thing by now on everything from CPUs to GPUs to motherboard and VRMs.

What would you have liked to see instead?
Unrelated to the topic but I wonder why no one does audio DSP on GPUs. AMD tried a few years back but the tech just kinda died out.
Efficiency of the power supply determines how much of those amps are actually available to you. And at any rate, I never see any measurements of amount of current the CPU is pulling anyway. Just some hand waving of "we have 400 amps so we are good."Usually people only care about VRMs to the extent of how many amps they can provide, to make sure they won't explode trying to power their CPU.

You can see CPU power draw in software.Efficiency of the power supply determines how much of those amps are actually available to you. And at any rate, I never see any measurements of amount of current the CPU is pulling anyway. Just some hand waving of "we have 400 amps so we are good."
I appreciate why they need it. It is the analysis that is lacking. Datasheet provides nominal ratings/max current ability. Devices in circuit don't work that way and have losses. Regardless, what I was disappointed about was them just reading part numbers after part numbers for boards. That doesn't say anything useful.You can see CPU power draw in software.
When you OC (automatic or not) the draw can quickly shoot up. I think the Intel 9900X can draw several hundred watts when OC'd which is pretty far from the 165W TDP. So you can see why people would want to know how much a board can handle.
Also, the output current rating is listed in the datasheet which is where the number comes from.
Seasonic have low end units that had bad batches before. Said units also use a decade old design.it's mostly a way to weed out the really cheap stuff. yes, it's possible to intelligently implement inexpensive fets to make something durable that performs well, but in the (literally) penny pinching world of the pc component aftermarket, that is generally not done.
there is also a certain amount of trust in the development groups for the enthusiast grade products at the major manufacturers that if they're tasked with implementing a 12 doubled phase vrm full of eg ir3555s, they will get somewhere near theoretical maximums for that set of drivers, and anywhere near maximum is massive overkill, and as such i should not have to worry about that portion of the board.
that said, it's really the wild west, and parts fail shockingly often regardless of what you do. there are few constants in life except for seasonic.
