Cooler Master Upgrades Warranty on its entry level PSUs to 5 years

Cooler Master, a leader in design and manufacturing of computer components and peripherals, today announces its decision to upgrade the warranty on its entry-level PSUs to 5 years. Generally, the entry-level power supplies are warranted against manufacturing defects and failure, anywhere between 2 to 3 years, however, Cooler Master as a leading brand in this space, wants to offer its consumer complete peace of mind by increasing the warranty to 5 years!

“Since last few years we have taken a serious approach towards bringing even better quality to consumers. With that in mind, we had revamped our entire series. The MIJ 1200W was the first to bring the best that is there to PSUs, from there on, we took the entry level and decided to set new benchmark! MasterWatt Lite (MWL) and MasterWatt E (MWE) our entry-level PSUs with upgraded internals offer excellent value, given their revamped internal circuits that can stand against harsh Indian power conditions. We are so confident on their quality that we have decided to increase the warranty to 5 years and offer our consumers total peace of mind.” – Said Sanket Naik – Country Manager, India.
