I have had great luck with corsair products. I go out of my way to recommend them to all my friends, they work out of the box and stay working till you outgrow them. Great psu's great memory great ssd's and great support to help if you have problems.
At the beginning there was only Corsair memory. But as time passed, what made Corsair awesome has been passed onto other products line. Their products are always top quality and warranty service top notched. Glad to see them stand the test of time and change PC hardware for the better.
Corsair hands down makes the best products in Memory, PSU's and Cases. Whenever I'm building a system I go to them for my needs or if a Friend is building a system I ask, are you using Corsair? If they're not, I'll rub it in on them until they buy. I've never had an issue with any of the products they make which is why I'm a loyal customer.
