My GUESS is that the mainboard embedded controller (EC) talks to the PSU and determines the max wattage the PSU can deliver. It then queries the CPUs, memory, drives, and GPU and determines the worst case power draw.If these are "close" you get the warning.
Still, 635W is pretty beefy and I suspect you're nowhere near that and BIOS and/or EC software is just being overly cautious (and Dell wouldn't mind selling you a bigger PSU).
I recently updated CPU1 in my T5600 from E5-2603 to E5-2660 and did not get the PSU message. I have the 635W PSU installed. (CPU2 empty, 32GB RAM, couple of drives, low end GPU)
eBay shows quite a few new/refurb 685W PSUs for cheap, I suspect these are the updated version of the 635W but I'm not 100% certain they are compatible with T5600. Also check to see if your BIOS is up to date.
I have had the same issue i went from a 4 core 8 thread to an 8core 16 thread. when i first booted it up with the stock gpu in my case a gtx 660ti it had no error so i shut it down no every time I start it up it has me press f1 to continue. I've done the calculation on psu calculators I'm only drawing a peek 400w or so so in theory I should be fine but i wonder if i tripped a switch and it just needs to be reset or something I've put in a generic video adapter that takes no power and still get the message. One thing to note is what your gpu is drawing and what connectors its using. mine had on 6pin coming from the psu and anther 6 pin was connected to two sata power cables. I have a cable in the mail arriving today that will fix this problem ill update if this also removes the error. another thing to try is to reset the CPU I read that in a similar thread and I'm curious if that will work if there are any bent pins that could cause errors in power management. i stress tested bot hgpu (980) and cpu e5-2678w 0 for 3 hours in a game and had issues with power or thermal throttling so I'm not at the max but with the cable ill be able to test a 2070 and see if any problems arise. let me know if you find anything on removing the error ive also tried updating bios no success (still woth doing there is a 2018 bios update out).

Did you solve the issue with power shortage alarm by new cable?
