Small correction to my previous comment: the 70 and 95.5 Watts were actually including the monitor (an old LG monitor) which was using itself about 40 Watts.
I wrote more about power usage (in idle) in my comment on this: h*****//w***pcx.hu/intel-core-i7-8700k-bx80684i78700k-processzor-689300

0.0 Watts consumption when plugged in and turned on from the button on the back, with the computer being turned off (so there is only one white led visible on the motherboard Asus Prime Z370-A). It sometimes jumps to 0.9 Watts for no more than 1 second. Sometimes it shows 0.1 Watts for 1 second, but most of the time it constantly shows 0.0 Watts power usage. (this might depend on my motherboard settings! e)
(measured by myself with "whitenergy ENERGY SAVER H&O Power Meter")
The fan stays off if the power usage is below 340 Watts (40% of 850W).
I have about 70 Watts power usage in idle (in Qubes OS) with Intel i7-8700K CPU and "Asus Prime Z370-A" motherboard. And about 95.5 Watts during Qubes OS installation on a 240GB SSD.
So I expect that the fan is likely to stay off all the time, especially since I don't have a dedicated video card.
Very thick cord power cable included. Two types of Corsair Link cables included (one cable is male USB mini B to internal motherboard USB 2.0 header). Many other modular cables included.
I am very pleased with this power supply so far. Thank you PCX for having such great goodies for us to buy so easily(I mean: buy online + cash on delivery)!
I will add more comments soon, about power usage for my configuration(that CPU+motherboard).

Az elmúlt 10 évben eddig csak Corsair tápjaim voltak, nem látom okát a jövõbeli változtatásnak, stabilan hozza a minõséget.
