Hi, first time builder confused as hell with PSU selection here. Sorry for yet-another-psu thread.
What's the problem? I've selected a Silverstone 450W unit, since adding up components' wattage (as closely as possible since not all manufacturers provide this info) and additionally consulting online calculators all confirmed the consumption should be around 400, if not below.
Then there are other calculators and GPU manufacturer who all recommend 500+ PSUs. I wouldn't mind going with a larger one, but since the box is intended to be a server first (24/7 uptime) and a gaming rig second, then efficiency is fairly important. Going with overkill PSU would be too ineffective when the system is close to idle.
Note that the system will be running on unraid and all gaming is to be done in a virtual machine, meaning GPU is essentially turned off when the vm is shut down.

Few calculator screenshots:
From these I conclude that overclocking would be no-go, but other than that, 450 should suffice.
Note that newegg calculator recommended whopping 588W and GPU spec page suggested 500W PSU.
What's the correct approach here? Am I mistaken that 500W (say this Silverstone) would be too inefficient when the server is idling?
Thanks in advance.
