Seasonic Issues Warning: FOCUS PLUS PSU has GPU Compatibility Issues
Here's something you do not see that often, Seasonic confirmed that their FOCUS PLUS power supplies can have issues with certain graphics cards resulting in black screens under GPU stress, the issue seems related to high ripple under GPU load.
The solution is quite simple though, some modified PCIe cables with enhanced shielding make the problem go away":

FOCUS PLUS and GPU potential compatibility issues
We have been notified, in limited instances, where some issues may occur when a FOCUS power supply is used in conjunction with certain high power consumption GPU or brand of VGA cards. If you experience possible compatibility issues, please check the below information and contact us for further assistance:
FOCUS PLUS & ASUS GTX970 STRIX: In very limited instances black screen may occur under heavy VGA usage. Current testing showed that certain VGA cards may emit higher than normal ripple when under heavy load and using a modified PCIe cables with enhanced shielding resolved the issue.
FOCUS PLUS & Vega 56/64: For units with serial numbers before January 2018, in rare instances, possible system shutdown may occur when GPU is under heavy load. This is possibly caused by higher than normal peak current emitted by this particular range of GPU's when under heavy load triggering the PSU’s internal protection safety.

I know it's a little unrelated but you just made me think of it, after getting a new powersupply I got one of those power protection boards to protect my pc from electrical surge, do you have one of those? worth getting in my opinion.... it's just a 4 plug out one > pc power supply > monitor > audio > extra for whatever else...
xD
for some electrical surge it can help... those surge-protector basically using MOV to absorb the surge power
it wont help for thunder surge that over 1billion joules
anyway rather than simple MOV filter, why not get a good UPS with AVR (Automatic Voltage Regulator) ... it should have surge-protector also so give much better power-line

I have Sesonic Platinum 860W SS-860XP and Today every time i opened a movie in fullscren in MPC + MADVR, my PC would reboot.
Doing 3D benchmark had no effect, using windows media also had no effect, I reset the MPC and now it works but Without MADVR .
It happened one time couple of days ago and a week ago it happened during opening web page tab.
I posted some posts but people says that 860w is good enough for 2080ti + 9900k plus 5 HDDS and otehr crap that I have like 480gb optane and 1tb nvme
EDIT: I opened my mouth too soon, after posting the initial message i opened furmark and got a reboot after 4 seconds
IMO seems more like gpu issue than psu. Problems you describe are gpu dependant, adding to it recent news about issues with 2080TIs i would assume your gpu is faulty. RMA it asap.

IIRC, the reviewer Oklahoma Wolf at the JonnyGURU site has several times made a point of noting that power supplies shouldn't supply two eight pin connectors on the same cable that connects to a video card unless they are using the heavier than normal gauge of cabling. He's noted how some cards can draw over the specification of 150 watts per eight pin connection, so you can end up with well over 300 watts getting drawn on that cable, and the lower gauge ones have sometimes been reported as having melted at the PSU.
So yeah, I can see rippling as also being a symptom of an overload. Some PSUs offer cables with just a single six plus two connection for the gpu. They can handle cards that draw over the specification, even without them having a heavier gauge.

Bought a Focus Plus for my Ryzen 2400G HTPC build. Didn't work at all. Have to RMA it I guess.
Anecdotally, my old Seasonic worked flawlessly, it's just some 5 years old, hence I wanted to replace it.
