Question 10900K power draw benchmarks

I've seen several benchmarks about CPU temps, from both sides, but I can't seem to find and tests covering power draw, which is my main focus on any CPU purchase.

Any one done such a test or has come across one somewhere?

Of the tests I have seen, they seem to suggest there might be something wrong with my cooling set up. Running x264/x265 (some encodes could be as long as 7 hours), my temps are constantly hitting 90c + with liquid temps > 40c on a 280mm H115i Pro, in a massive case with 11 case fans on both a delidded 7900X and a stock 10940X running at a lowly 4.20ghz

Before I go and splurge A$1600 on a new 10900K and new motherboard, I'd like to know how it's going to affect my electricity bill.

I did read this post: https://forums.tomshardware.com/threads/intel-i9-10900k-10-core-flagship-cpu-tested-runs-very-hot-consumes-235w-at-4-8-ghz-with-over-90c-temps.3605203/

However, I couldn't see any links to any tests to substantiate the data provided, and it was pre-release, so potentially just rumor. (though the 9550pro link fails to connect for me so I don't know what's there).

I saw that. I've read it a couple of times. Can you please point me to where it shows the power consumption for various tests at stock and overclock speeds, because I can't see it. I did read page two but it wasn't what I was looking for.

nvm. I will just skip the 10th Gen CPUs

Here is a temp review by JayzTwoCents. This is the sort of thing I waslooking for.

@gtarayan from my earlier post...

I'm not looking for a comparison to other CPUs. I'm looking for some real time power consumption tests with stock, turbo boost and overclocked results, similar to the review JayzTwoCents did.

Anyway, I guess I can't really justify A$1600 per PC to upgrade 8600K CPUs. From the review it seems I will only be getting single digit performance improvement for a significantly higher annual power consumption after upgrading 4 PCs. Given that 3 of those 4 are used mostly for gaming, the extra cores aren't worth the A$1000 price tag for the CPU.

Your motherboards are probably pumping way too much power or volts or both into your CPUs,you have to tune that manually.
Or as the link in post #4 says:
"While Intel designed its 250W limit to keep thermals 'manageable' with a wide variety of cooling solutions, most motherboard vendors feed the chip up to ~330W of power at stock settings, leading to hideous power consumption metrics during AVX stress tests. "

Here is a very informative video on this topic.

Nobody makes reviews where they show power draw next to each test they do.

@TerryLaze.

Thanks for that. I don't have a 10900K yet (and I probably won't buy one just yet),

My existing CPUs are 8600K (3), 9600K (1), 9700KF (1), 7900X (1), 7820X (1) and 10940X (1). All are overclocked moderately, but I have not tweaked voltages on any of them. I also have an I5-8500 but it runs stock.

All PCs run H100, H110 or H115 Corsair cooler variants.

The 7900X and 9600K are on an ASRock motherboard, the rest are MSI motherboards.

I guess I should try dropping voltages and see what happens, of you think that the motherboard vendors over power them.
