How and why would that be? It's accurate but obviously is going to put a positive spin on things.
It's not like their lineup is trash, just often more expensive than you can get from others. Also, it seems like they skipped over talking about VS and CX in the main text, and those are the cheapest ones.
Those "TX products" that were replaced were rated for 50C, had all Japanese capacitors, and just better build quality and electrical stability than the products in the mid tier (CS-M, RM) of pricing and lineup that are newer, for example, but they don't mention that. Also maybe lower prices at around the point they were getting phased out. Something's got to give when you're able to offer 80 plus gold, modular cables, and lower noise at similar prices.
If you look closely, not like it really makes much of a difference in reliability based on usage in the product and so on, but AXi isn't listed as having all Japanese capacitors. Bucks the trend, huh? Some people complained about that. Also, its dual ball bearing fan is worse than the one used in the regular AX.
Also, some may say Corsair Link is varying degrees of buggy or inaccurate. I don't know about the bugs these days or if it still has issues, but the accuracy isn't going to be as good as lab instrumentation that costs anywhere close to the cost of the power supply, never mind orders of magnitude above it. No duh. There will be limitations there, though performance and accuracy could be surprisingly good sometimes. Just keep expectations realistic.
In other words, read between the lines, as with anything? But the info there is fine.
