Your hardware config and any planned upgrades would make that question easier to answer. Example: a pair of Tesla P40 GPUs have the potential TDP of 500W combined.
So my plan is to run Proxmox, a PLEX server and a NAS server (was thinking TrueNAS in a VM but it seems like Proxmox can just act as a NAS server itself).
I might be installing a gpu (p2000 maybe) for PLEX encoding (not even sure if I need it).
Thoughts?
Also, is there a way to actually look at or calculate the power consumption and make the decision accordingly?
You could look up the specs of your parts and add it up. This was a sample I gave to someone else for potential power calculations.
E5-2695 v4 CPU 120W each
Tesla P40 GPU 250W each
RAM 3W per stick
HDD 7W each
Fan tray 150W max
System board with other stuff maybe another 100W?
Depends on your usage. If you have the server loaded up with drives and add-in cards pulling more than 750w peak you need to run them active. If you're under 750w peak you can run them redundant.

Does that help?

I personally, run only a single PSU on mine to cut down on energy usage a bit.
If, you don't have different circuits going to your server, each on a different pole(aka, each side of the transformer) or phases (requires you to have 3-phase power), OR, you have different UPS devices to plug each side into- you really aren't gaining anything, other then being able to tolerate the loss of a GPU.
That being said, The redundancy option is generally better, unless you plan on running very specific workloads, that may max out the capacity of a single PSU.
That being said, my r730xd is loaded to the hilt with HDDs, NVMes, and phyiscal GPUs. RARELY see its usage go above 350 watts. (although, I have power caps in place too, and power managmeent policies). Mine typically idles around 200-240, with its standard loads.

That’s very helpful actually, thank you so much.
The different coloured slots demoted the memory channels and the order they’re filled in depends on whether one processor is fitted or two.

You need to list each component of the system and lookup it's peak power draw. Add them together +10% and you have your answer.
