The 8600 k has 6 cores 6 threads, not 6/12. Bit of a blooper there. Referring to "note, Intel's 8600k doesn't come with a cooler), 6 cores and 12 threads want cooling and can run warm and hungry"

Warm yes, really hot no. H7 deals with it just fine. People keep saying these chips are hot but in my experience, not the case. I guess I got a good chip. OC'd to 4.8ghz @1.265v It never goes over 75 (and that's rare, it's usually 60c when gaming.)
I think it is still consequence of having happy memories from Sandy times. Good cooler could keep it under 65C under full load and OC.

Only Crazy OC got it to 75C and that required very uncomfortable voltage too.

Thanks for the roundup review, and I also appreciate the beach pic - it really does feel like Summer! Quite amazing that GTX 1070 is still being recommended, being more than 2 yrs old, but I don't mean that in a negative way - it's just testimony to the fact that Pascal has been with us for a long time and the next architecture is ripe for release; I can also testify to GTX 1070 for high refresh rate 1080p gaming - I have one and it's great for that.

I will revive this thread a bit.
Hilbert did put into list of PSUs: EVGA Supernova G2/G3 650-750W

I happen to have Supernova G3 750W. And I came upon very unpleasant realization that this PSU draws insane wattage even when PC is OFF. It is at least 50 Watts as it triggers master Switch inside my electric expansion block with multiple sockets. It is configurable from 8W trigger to 70W trigger on Master. Once Master power draw goes above set threshold Slaves are enabled.

I'll have to get one of those wall socket readers with display to get "exact" readings, but my 40W devices are not enough to trigger Master Switch unless I dial it down.
I have found quite a few people noticing same. And PSU which they sent as new after RMA displayed same behavior.

When I tried to find out reason, I disabled all standby features in BIOS including WOL, timer start. Fromm what people wrote this power consumption is passive even if nothing is plugged into PSU.

That is unusually high, but I wonder if there's more to it. Are you sure it's the PSU and not the motherboard? The motherboard still draws power from 5vSB pin (the purple wire on the main 20-pin connector). Though, usually that's no more than 15W. There are some things in BIOS you can't disable where the mobo will still draw power no matter what.

If you unplug everything, is the wattage still very high? I don't expect it to drop all the way, but a lot of it should.

Many PSUs drop practically to 0.5W or less. EU requirements is sub 1W in standby. Thing is that X470 Taichi does not have EuP option in BIOS. And manual states that it is certified with it, but requires compliant PSU.

Hilbert's test of Taichi shows that it draws tiny bit only when system is powered off. My 1st suspect was system which controls LED blinking as that runs even when system OS powered down. Maybe there is some unrelated option in BIOS which initiates small power draw and in that state PSU can't eat less than that. But that would be crazy.

I messed with all kind of BIOS settings for few hours today to no improvement. Then shuffled plugs on PSU where things are connected. Then some combination in BIOS reduced Power draw. (At least I think so. Because for confirmation I have to shut down both systems and unplug notebook from Master Switch.)

Edit: Yes, seems to be fixed. Luckily I found out after owning this PSU for few months. Finding after 2 years would make me pretty angry. As that additional cost for doing nothing would be enough to buy 3 times as expensive PSU which does not do this under some conditions.

(That's for not being paranoid for once and presuming that generally well reviewed component does not have Goblins hidden somewhere.)
