I had googled it before posting this question. However, I couldn't find any related information about that model. If it is an old model, I should be able to find something about XP-500+coolermaster. However, the answer is no. Therefore, I need an official reply. Anyways, thanks for your kindly reply.
Is there any power supply named as "Cooler Master XP-500 eXtreme Power 500W P.S. "? I saw one in Hong Kong and I am not sure whether it is an old version, the latest version or an fake one. Please confirm. Thanks
