Thank you very much for the tutorial. It's really nice.
Have you set a custom gpu memory via bios?

No I haven't yet looked into allocation of memory to GPU. I will add that to my list.

With this build I went to a single mass storage/NVMe decice. Usually I build with two devices and limit the size of C: to Windows 10-only and use Disk Cleanup to keep it small. Then I use the builtin Windows image-Backup/Restore to quickly restore previous versions of Windows OS in case something gets corrupted.

For this build I have only one NVMe drive and was planning to do without image backup/restore. But I miss it too much so I ordered a second NVMe 1TB drive.

Really neat little build and great log!

You could also look into powering it with the Meanwell 120w AC/DC unit, as it is much smaller than a FlexATX power supply.

Thanks, I appreciate the work being done with the Meanwell 120w AC/DC PSU. Yep, that was one of the first PSUs that I looked at. But I had some issues for this specific build:
  • It requires additional "pico PSU" parts to connect to the motherboard.
  • The pico PSU may not fit some case/motherboard combinations without removing the Pico PSU heatsink.
  • It requires crimping or buying pre-crimped cables to connect to pico PSU.
  • The Meanwell's smallness requires an extra C14/part and extra case space to connect to wall AC power.
  • Yikes, the Meanwell PSU is open without a protective cover, maybe for heat dissipation? I dunno??
The Meanwell was going to end up being much more costly than my $28 used (server/Flex-ATX PSU) which fits nicely in the bottom of the K39 case held in place by two common screws/no metal mods or holes to drill. There is a little extra room at the end of the PSU for coiling the excess length of the 24-pin ATX power cable. Aside from starting with a howl during a brief full-speed fan test, the PSU runs silently for this APU build.

However/Caution/AFAIK: Server/Flex-ATX PSUs can end up being too fan-noisy for home use. This PSU runs silently in my APU build but may get fan-noisy in a gaming build that draws more power.

eta> Here's an image of the two-cable simplicity that I ended up with. Just install the ITX motherboard and Voila, the two cables (24-pin ATX power and 8-pin EPS motherboard power) are right where you need them;

For this build I have only one NVMe drive and was planning to do without image backup/restore. But I miss it too much so I ordered a second NVMe 1TB drive.
Now I have two (1TB Samsung 970 EVO+ SSD V-NAND M.2 2280 PCIe NVMe 3.0/Gen3) drives. I moved my Libraries (Documents, Pictures, Music) to the second/backup drive. Now the only thing that resides on Drive C: is Windows 10 OS and the software/Apps that I have installed.

I used the Disk Cleanup Tool with the (clean up system files option) to whittle down the contents of C: drive to 34GB and proceeded to use the Windows builtin image Backup/Restore tools to test the procedure for reverting back to a previous version of Windows OS plus installed software.

WOW!! It is fast, about 1 minute and 45 seconds to backup an entire system image of the 34GB C: drive. Restore is even faster, about 45 seconds to restore a previously backed-up image.

Now I can load whatever software without worrying about future implications/trial versions/viruses/etc. Soon I will resume testing my memory timings for this build.

Nice to 'hear' you've found a silent Flex PSU!

Will look forward for your memory timings and allocation as I am doing an AMD APU build too.
