Yes, true! As I mentioned before, most of the power supplies are equipped to handle an AC voltage across 100-240V.
For a problem that is as spread as this one, with many cases reporting that a power supply did not help, I didn't necessarily feel the need to throw more money at something not concrete. Seasonic is well known for making some of the best power supplies in the market, that said, it still doesn't mean that mine is a 100% fault free, But taking a chance on that is not worth spending the extra money, definitely not for a downgrade from Platinum to Gold rating either, specially when I live in a country that you just cannot return used stuff like electronics, unless they are faulty.
@Shade7, no one really knows where the EMI "if it was even the culprit" is coming from, or is it the same common source for everyone, even with a solid steel panel, you still have your cables exposed outside. Interestingly enough, the whole "Spread Spectrum" feature that you find in your motherboard was introduced mainly to cut costs on EMI shielding from within the motherboard. So why pay more in manufacturing to provide better shielding when you can just add a feature that messes with the end user's BCLK frequency to distribute the total noise among multiple frequencies instead of only one. You're still getting the same amount of EMI from your poorly shielded motherboard, but the peak noise now is well within the "pseudo" standards.
It's even more frustrating when you think of Asus for example and their ROG lineup of motherboards for Z690s. Their Apex $799 which is supposed to be their crown jewel when it comes to extreme overclocking had an entire batch with bad traces in PCB design effecting the signal integrity of the ram slots making it impossible to post and stay stable on any frequency above 6000! Even their " ROG Extreme" one which is $1199 exhibited the same issues with its PCB design, a BIOS update didn't solve any of those problems and users where just fuming over their forums. Let's not forget about their most sold and beloved "Maximus Hero" that also had an entire batch with a capacitor placed the wrong way causing it to catch fire. I can't even imagine how bad manufacturing standards and quality control have to be for these kinds of issues to happen. But you get the point, they will try to cut costs in any way possible.
They never went public with either the Apex or the extreme models specific batch problems, why should they, they already took a big hit with their most sold one "the Maximus Hero" catching fire. The Apex and Extreme users are on a niche market, they won't be heard as much, and chances are, at least for the Extreme models, that users will think surely the RAM or something else is the problem other than thinking their lovely $1199 motherboard is. It needs tremendous amount of troubleshooting and time to detect these issues, specially if you're the end user and you just don't know where to begin. Issues that should be already been detected with well established and complex quality check procedures.
But then again, Asus was literally glorified for taking action and going public about an unthinkable mistake like having an unhidden capacitor soldered the wrong way! Something that a random overclocker on youtube figured out just by looking at pictures. A mistake that a first level line of quality check would've easily detected, but nope, people like JaysTwoCents who preach on being for the consumers just went on bullshitting his way on how gracious Asus is for taking action, and it's "what they do after that matters" lol. I wish people can see through this guy's bullshit. For the love of God, he is sponsored by them, Instead of ridiculing them for something that it should have never happened in the first place, specially for a motherboard that costs $499, he placed them on a pedestal and explained how the entire thing is because they needed to build more and build faster "to attend for the shortages". Linus for example is heavily sponsored by both intel and Nvidia, yet the dude never seizes the chance to call them out and point out what problems they have on any occasion, never commends them unless for a good product, and always ridicules them for the mistakes they make, either with their product lineup, quality, or pricing. Apparently he signs the sponsorship contract on his own terms unlike JaysTwoCents.
The moral of the story is, we are doomed.
