This is pretty much all I needed to hear. Thank you :)
Comment on Can anyone tell me what PC will draw more power?

A few points:
- The redundant (second) PSU on the server is not using power (at least, not much) unless the other fails. Its job is to be available if the other PSU fails, or if power is lost (you typically have them on different PDUs and fed by different UPSs.
- Almost any desktop is going to use less power than a server, as servers don’t bother with power-saving features or power states other than full tilt into oblivion.
I won’t go into the research required to give you a quantitative analysis, but suffice to say that a server > desktop in terms of power usage IN MOST CASES. Of course, if the desktop is running four 250w GPUs and running crypto or other full-time workloads, it could exceed the server, but all things being equal, well, you get the point.

While actual power consumption won’t be much apparent power (VA) will be a measurable amount. If you’re connected to a UPS and it’s not a super modern server then it’s apparent power will be a decent amount. As a normal end user you don’t pay for this, but if you’re trying to spec out a UPS you’d want to calculate it and factor it in.
The FX 8350 isn’t a very power efficient CPU, but two E5645 in a server is going to use a lot more power at idle (and load) than the FX. Servers actually have pretty manageable power usage, but idle consumption of a dual CPU system will always be more than a single CPU system.

Well-said.
