if I understand this correctly, a low efficiency 750w psu generates same amount of total 12V power compared to a 750W 80 plus platinum. the low efficiency psu just wastes more wall outlet energy compared to the platinum, and generates more unwanted heat inside pc case.
It should, yes. But in order to reach the type of efficiency needed to meet the Platinum level, the internal components need to be of high quality.
That in turn will lead to better overall performance, less ripple, less drift under load etc...
The ratings are also an indication of the quality, because with lower quality components you will not be able to reach the higher efficiency. Not saying that a lower rated PSU is not good, it's just not as good as a higher rated.

These are the OEM dimensions for video cards: OEM dimensions
Be aware of power supply requirements for 3080 video cards. Should be 850 Watts or higher.

Re: anyone know which 3080 cards will guarantee fit in this thing?
as long as the 3080 is not longer than the Dell oem one, it would physically fit.
Dell OEM MSI GeForce RTX 3080
Part number = 4Y12V
Platforms = Aurora R12/R11/R10
Card dimensions = Length: 267mm, Height: 114mm, Width: 50mm

The R13 comes with a 3080 and a 750w PSU.

The new R13 & R14's come with a 750 watt power supplies? and have 3080/3090's with it?
So seems a 750 watt power supply would be sufficient with a 3080?

Yes, but this was for an R12 shipped with an RTX 2080.

yes. basic online psu calculator for i7-12700k and rtx-3090 Load Wattage:645 W
Recommended PSU Wattage:695 W
R13/14 need more power than the calculator recommended because of use of liquid pump. so add 50w extra to that you get 750w psu.

Only if the efficiency rating is equal or better than the one used in the R13.
It is Platinum rated, and they demand a price premium.
If you would go for a gold one, I would get an 850 rather than a 750 because of the efficiency rating loss.
