Question Corsair HX1200 vs SeaSonic Prime PX-1300

[Wolverine2349]

Which is the better power supply.

The Corsair is a rebranded CWT and is good per reviews.

SeaSonic has a reputation for making top notch PSUs

Though JohnnyGuru who now is unregistered and his posts are as guest in that thread says SeaSonic is crap and the Corsair is way better. Is he biased cause he works for Corsair or does he have a point.

Which PSU provides better power delivery and better ripple suppression. It seems the SeaSonic PX-1000 based on reviews which I could find, though no reviews for SeaSonic PX-1300. Is the PX-1300 just a more watt version of PX-1000 or have there been some changes? That would especially apply to a dedicated cable to RTX 4090 as Corsair adapter has no filtering caps so SeaSonic seems to have better native filtering as their cables have no caps and Aris reviews show it has excellent ripple suppression anyways.

Which one is better bet for mitigating/eliminating coil whine on video cards as much as possible?

And which one is better for overall quality and system stability?

Is it true SeaSonic caps do not have as high of a temp threshold being only 40C where as Corsair and Super Flower based units can go up to 50C. And if so is that important or much more to the story and SeaSonic could still be better anyways??

And do SeaSonic Power Supplies still have the tripping issue with Ampere cards and if so would the same apply to the RTX 4000 series??

Corsair HX is better. Better platform, better fan, better fancontrol, better protections (because of the 12v multirail design) and 50 degree rating instead of 40 degree. Above 40 degrees the Seasonic is a 1040w PSU.

Yes, this is still the case, but more for the 3090/ti. Yes, it will also impact next gen 4090/ti. Perhaps even to a bigger extent. Haven't seen the testing on it yet though.

The Corsair 12vhpwr adapter has no filtering caps and the filtering caps make ripple suppression excellent on it and no 12vhpwr direct connect 12vhpwr with the caps.

The SeaSonic Ultra Prime PX-1000 seems to have great ripple suppression without filtering caps

https://www.tomshardware.com/reviews/seasonic-prime-ultra-platinum-1000w-psu,5397-9.html and caps can do 1000 watts at 47C

Is the PX-1300 the same as 1000, just rated up to 1300 watts at only 40C instead of 47C, so could it maybe be a better 1000 watt PSU than the HX1200, but the HX1200 is a better above 1000 watt PSU.

Cause only need 1000 watts and no more but excellent not just good ripple suppression and direct power delivery without adapters to RTX 4090 are critical to me.

And the 12V dual rail is not important to me as I never use it.
