I do hope it's not the PSU; just bought this Seasonic Prime Ultra 6 months ago, and was working fine in my previous build, an i-7 6700k on Asus 170 deluxe - and I do not have an older psu i can test, unfortunately. Though I will reapply the TIM - thanks for the tip.

Well, it's not the thermal paste. If only it were this simple!
I reinstalled the heat sink and fans, this time using Noctua NT-H2 instead of my usual Kryonaut, but I'm not seeing any significant changes.
It just seems that the system never truly idles down; voltage remains at 1.46V most of the time, even when idling/low usage (it occasionally dips below 1.0V, but only for a second). This despite the fact that I'm running the latest chipset driver and BIOS, which were supposed to fix the idling issues.
I ordered a PSU just to exclude it; if it is the PSU I'll have to RMA and then return the new unit for a refund if this does indeed turn out to be the issue - I've already invested too much already.
Back to 'power saver mode' and 2.1 GHz for now...

Turns out it was the PSU after all...
I was getting some high voltage and power readings in HWiNFO64, and decided to go ahead and order a different PSU thinking that I’d always be able to return it to Amazon within 30 days. Well, seems like my original unit, the Seasonic Prime Ultra Titanium 1000W, was way off :
- CPU core current: average: 20.89 A
- Core power: core 1 power average 1.12 W / core 2: 0.94 W / core 3: 4.34 W core 6: 1.80 W / core 9: 1.34 W etc.
- CPU core power average: 30.12 W
CPU die/package temps from 55-62, with a minimum of 48 with no apps running.
Compare this to the (temporary?) replacement PSU, Corsair AX850:
-CPU core current: average: 9.34 A
- Core power: core 1 power average 0.50 W / core 2: 0.27 W / core 3: 2.22 W core 6: 0.13 W / core 9: 0.10 W etc.
- CPU core power average: 13.08 W
CPU die/package temps from 45-50 on average load, 40-45 when idling/low load. *
So... I invested quite a bit in the*Seasonic, and I am rather disappointed. This is a 6-month old unit, and Titanium to boot. It’s possible the unit was already off in my previous i6700k build, but I never noticed anything on a lower core CPU.
Anyhow, I’m relieved as this seems the solution; still waiting to hear back from Seasonic to see what they can do.
As the temps/voltages have gone down, so has my blood pressure!

Hey Derridada.... how is your system now?
Can I expect any problems with AMD build? Any problems at all?
Thanks a lot!
