So I may have finally figured out what was has been causing my Windows WHEA_UNCORRECTABLE_ERRORs and Linux to stop recognizing my NIC and Kernel Panicking.

 

According to the ASUS PRIME X399-A my 5V rail is 4.5V. Now this would be less concerning if this was while under load but this was while idling in the BIOS. For a lot of electronics they market that +/- 10% is within operating spec but if you're already @10% and the system isn't being stressed I can see that going far enough to cause the system issues. I validated that this was the cause by plugging in my 10-ish year old Kingwin Lazer 1000W and running the system for a week or two. All issues disappeared and the BIOS reported the 5V rail as ~5V.

 

So the problem PSU is a original Corsair AX1200i

Quite frankly I'm disappointing. This is a pre-mature death. I bought this back in 2013 so it's only currently about 6.5 years old and I've never pulled over 750W-ish from it ever so it's had an easy life.

 

Now I've always had a habit of dismantling things because I just have a very curious nature. Also for dusting things out. To my surprise though and very unexpectedly I've never actually voided the warranty sticker on this thing:

So, I'm going to see what happens if I try to cash in on the warranty. For the AXi series specifically Corsair currently offers a 10 year warranty of which I'm only in ~6.5 years. Was it 10 years 6.5 years ago? No idea but I've already sent them a message though their support website so we're going to find out.

 

I do hope all they ask for is the PSU itself if it's approved and not all the cables since I may have voided the warranty on those if that's possible. To buy the updated unit today would cost $340 + tax & shipping (for me would = >$400) so I'm really hoping they let me replace this under warranty.

 

One of the reasons I switched to Linux in the first place was just to try and get away from WHEA_UNCORRECTABLE_ERRORs but seeing Linux have errors of it's own kind of cancelled it out. Even if replacing the PSU does fix my problems with Windows I don't think I'll be going back. Windows in a VM with GPU pass-though and some CPU/RAM optimization performs almost as well and I'm just liking working with something different.

 

Though Ubuntu 19.04 is having some buggy issues of it's own I need to research and work out.

    WHEA_UNCORRECTABLE_ERROR is almost every single time caused by hardware, whether it's bad power/voltage or just unstable frequencies (when oc'ing) so I'm not surprised it ended up being the PSU.

    I've dealt with this error for so long I've grown quite familiar with what causes it. Guess I was just in denial not wanting to blame the high quality >$300 PSU. I'll post back on weather or not Corsair will accept the RMA.

    Shit. They are accepting the RMA but they want all the modular cables back of which I have done various things to over the years. Don't know how well this is going to go but I guess I'll find out. Might not be getting that replacement under RMA.

    They did accept my 6.5 year old unit and sent me a brand new one. That's pretty cool of them. I'm going to give it a workout and see how it handles.
