For a desktop PC I care most about the TDP value of the CPU/GPU, than
about any other CPU/GPU value.

Is hardware video acceleration a domain of FreeBSD apps?
In the recent days I experimented for the very first time with hardware
video acceleration on my Linux machine, just to notice that it works
with mpv from command line, but actually _no_ web browser does support
it.

I'm using a 600 W PSU for a machine that is probably less power
consuming, than the hardware of the OP's links might consume, let alone
that the power consumption is no reasonable value for the provided
Ampere at the other side. I don't know if it's the mobo, the OS (Linux)
or the PSU, while USB3 bus power is fine, USB2 bus power is a PITA. I
need to use very short cables and sometimes even an active hub. I
suspect the PSU. The reason that I didn't bought a PSU able to provide
more Ampere was a question of money. I simply couldn't pay for another
PSU.
I would be careful when calculating real power consumption. What makes
you think that adding 33% is a good value?
The PSU does consume power on demand, it's better to have headroom.
Power saving is done by avoiding oversized CPUs etc., resp. for
"TV/cable (download/stream shows)" probably via hardware video
acceleration, if available.
