Anyone else feel like Corsair has lost that special edge?
Nah, they never had anything particularly interesting for at least a decade.
What they were good at was availability.
Their cases have been average from the start. They usually oversize it to compensate for any airflow design flaws.
Their maglev fans have bearings that are trash.
Their AIO/CLC are decent, but they're kind of expensive for what they do.
Their keyboards had an edge in a sense. Their earlier designs had folded aluminum mount plates that were oversized and it had very sharp corners and edges.
Their mouse were never good
Their wireless headsets were good for a time, but they never bothered to improve it so now they are just average.
Their RAM and SSD lineup has good availability, but prices are premium and quality varies.
Their PSUs are great, but they like to skimp on the fan.
Their prebuilts are okay, just like other brands that offer prebuilts.
I think their Xeneon Flex monitor is their most interesting product, but it's so expensive.
