Do some Mac Pro 2019 have different power supplies?

I purchased my Mac Pro 2019 immediately when it first became available . A year or two later, we purchased another Mac Pro 2019 for my wife. Both of us recently installed the AMD Radeon RX 6800 XT graphics card into both computers.

We were comparing Power Consumption usage in the AMD Software and noticed that our power consumption is significantly different. We both use Steam for video games and both of us are running the exact same games and her numbers are way lower than mine. Running a couple of games on my computer, my power consumption is around 255w while running the exact same games on her computer the power consumption was in the low 100w range. That seemed odd unless the Mac Pro 2019, came with different power supplies, based on when it was ordered?? Thanks.

That's a really interesting theory, but its wrong.

There may be a few minor engineering changes to later power supplies, but they would not be detectable.

The difference is FAR more likely to be what is running in the background on each machine.

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners, Bit Torrent, or a VPN that you installed yourself.

¿Are you running any of those one either machine?

Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance as well, but are not inherently dangerous.

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by senior contributor here, and uses system calls to collect often-needed information.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.

Use Etrecheck Pro for free:

then start a reply on the forums, click the 'additional text' Icon in the forum footer, and PASTE

Thanks for your reply. No, neither of us are running any of those types of items on our computers. I also have these unusual instances where sometimes my computer will have an issue where I can not power up my computer with the power button. To fix this issue, I have to unplug my Mac Pro, let it sit there for 20 or 30 seconds, plug it back in, and then it will power up like normal. Maybe it is just my power supply that is acting weird. This does not happen often but it does occur from time to time. Also, during these power supply issues, I am on Windows 10 via Bootcamp playing Steam games and something has occurred like I am switching from the Mac side to Windows 10 or something has occurred on the W10 side to maybe lockup or crash the computer.
