I have a retail store and i purchased a few power supplies from Coolermaster. I installed one of them into a customers computer and it kept shutting off. I realize with components this can happen. Unfortunately, i can not for the life of me understand the logic behind they way coolermaster does their RMA. I have been waiting for almost a week and i still have the faulty power supply sitting by my desk. I have heard from coolermaster and the email was telling me my ticket is pending. ARE YOU SERIOUS!!!!!! the website they have is terrible for customer service. i will never recommend any product from coolermaster again. this was a real eye opener. Now i know how the end user feels.
