requires:

+ 87% + PSU efficiency

+ Incorporate Energy-Efficient Ethernet functionality

+. Transition connected displays into sleep mode within 15 minutes of user inactivity

+ Transition the computer into either the computer sleep mode or computer off mode within 30 minutes of user inactivity. If the transition is to a computer sleep mode, that sleep mode shall either as described in ACPI as S3 or

  Consume power less than or equal to 10 + 0.03 * C, where C is the system memory capacity in gigabytes minus 32 gigabytes (see Table V-6 in Title 20 Section 1605.3(v))

i was gonna try to summarize in simpler words but im laughing too hard at the last bits there

Umm what? Who came up with this? Is there any scientific basis behind this?

It makes sense. Out of all components only RAM’s power usage scales linearly to it’s size. You need to periodically refresh each single memory cell to not lose it. Everything else you can either switch off or move to standby.

87% + PSU efficiency at 100% and 20% load. 90% + PSU efficiency at 50% load.

Power factor of 0.9 at 50% load.

(Monitors must go to sleep within 15 minutes of no input)

Is watching a video considered "input"? And are these regulations enforced as default settings and do users have the ability to customize the settings? Or do they want the manufacturers to disable customization too?

It says inactivity, not input. Generally doing thinks like watching video is considered an activity.

it can be taken to mean two things.

the monitor itself has to go to standby if the port it is switched to has no input (as in, the computer is not outputting anything on that port)

and

the computer has to switch the monitor into standby mode on user inactivity.
