Having recently had a failed AX850 power supply RMA'd by Corsair's ticketing system, I can only describe the experience as top notch. Their initial advice was professional and courteous and the RMA process was made as painless as possible by Corsair. I have had an RMA with them before with a faulty memory module and that was equally impressive. Am I a Corsair fanboy? I suppose you could say that because I own quite a few of their products and have found them to be of outstanding quality but the important thing here is if there is a problem, you can rest assured it will be dealt with in a manner which is sadly lacking with other vendors nowadays. No quibble, extremely prompt and friendly. If any one reading this is thinking about purchasing any Corsair product then I would thoroughly recommend them as a company that actually cares about it's customers. I don't work for Corsair nor have any affiliation with them, I just thought I would highlight my experience because forums can sometimes be a source of complaints and bad dealings, this is the other side! Thanks again Corsair.
Kind regards, Kie
