whatever for?

28 core xeon CPU = 300W
12x 128GB RAM = (maybe?) 550W
Vega Pro II GPU = 475W

a long way from a normal PC then.


Okay, a fairly typical example of a slightly older PC with a highish end
(for the time) processor and a medium range (?) graphics card (the one
my three sons had until a recent upgrade:

CPU: AMD FX-8350 (not overclocked)
Memory: 2 x 8GB DDR3
Video: NVidia GeForce GTX 1050 Ti
Storage: 2 x SSD, 2 x SATA III 7200rpm HDD
PCIe cards: Single port Ethernet, DVB-T Tuner
Keyboard: Gaming keyboard
Mouse: Gaming mouse
USB devices: Hub, external HDD, Sometimes a couple of Arduinos
Other devices: Integral card reader
Fans: 4 x 120mm
Usage: 8 hours per day, 4 of it gaming

Using an online power requirements calculator, that gives a load of 424W
and recommended a PSU of at least 474W.

Adding a second graphics card in SLI mode (as huge numbers of gamer do)
would bump it up enough for a 650W to 700W PSU to be required.

With respect for an old pc 16G ram, 4 hdds/ssds, 2 arduinos, 4 fans is a long way from a typical pc. Bit pointless isn't it.
