new PSU causing lots of audio and mouse issues

[Maelstrom]

Hey, I recently read a post about electricity lag and felt like I could just try out a new PSU as a quick check to rule out issues.
I went from a seasonic prime tx 750W PSU to a corsair HX1500i.
The symptoms I wanted to fix were mostly related to input lag and very bad hitreg in games (but otherwise the system was problem free and was mostly stable).

Since making the upgrade, I've noticed my FiiO E10K will over the course of 20 minutes fizzle out and stop working until I reboot the PC.
I also have an OP1 8K mouse which I've used for several months without issue. Since the upgrade, the mouse itself is causing huge frame time dips in Quake Live and in Kovaaks, all the way down to 20-30 FPS (on a 7800x3D system).

has anyone noticed something like this?

if connect fiio by optical cable without usb cable, fiio is get downed?
you mean frame drop on 8khz?

I believe both Kovaaks and Quake Live don't have a separate mouse input thread, so you can experience performance regression if you run your mouse at >1000Hz polling rate settings. Potentially messing with core affinities might alleviate this behavior, but I haven't explored this topic.
However, a PSU change causing such an effect you've described is something I've never read before.
Have you done anything else to your system to trigger this? This is completely abnormal behavior, possibly even faulty hardware levels of broken.

false alarm, I lost track of my changes.
The FiiO does fizzle out since the PSU swap, I'm about to swap back this weekend when I have the chance to see if the issues go away.
The mouse issues are purely from HPET being reenabled. I'm surprised it had such an effect, but when disabling HPET the issue is completely gone.

that is quite crazy, could it be damaged maybe? I also want to add, that someone else bought a corsair hxi and measured it with one of these line emi meters and the corsair had much higher readings compared to his previous psu, which I don't remember the model.

I've never read of a single person experiencing (visible) drops to 20–30fps on a 7800x3d in Quake Live & Kovaaks from having HPET enabled (which is the default on almost all platforms since the inception of it)
Your actual problem lies elsewhere...

This is a repeatable issue, I can take a video for you if you'd like. Your summary misses one detail which is that this is directly caused by HPET being enabled, and mouse movement from an 8kHz mouse. If I play with HPET enabled and an 8K mouse but don't move the mouse, there is no drop.

The frame drops aren't just some sort of issue with the performance monitoring either, they are very visible and noticeable.

I've swapped back to my previous PSU and now the audio issues are resolved. Really weird, not sure what to think.

The mouse input issues were unrelated - but in summary don't use HPET with an 8K mouse? Curious about whether other people come across this issue.

i also have 8k mouse but i cant disable hpet,i dont see the option in bios,on my last mb wich was also asus i use to disable it via scewin,but now on the new asus mbs it does not show it.

Please do, because this can also be benchmarked with PresentMon & logged with a .etl file & then explored with WPA/xperf/xtw/MXA as a objective measure.
I've yet to see this occurring on AM5 on other X3D + 600 or 800-series motherboards.
