Which is the better power supply.

The Corsair is a rebranded CWT and is good.

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??

Don't really have an answer to which is better. But I would (and do) ignore JohnnyGuru's opinions these days. He used to rate Seasonic very highly when he had his own review site. Now he works for the competition and says they are crap. Figure it out.

I was looking at these PSUs recently too and went with the Corsair one, since it often goes on sale for $230-ish and was $100 less at the time I was buying. You do have to spend $20 extra for the 12vhpwr cable though, and it's very hard to find in stock. I just managed to get one from the Corsair site.
