Cooler Master RC342KKR400U3 Elite RC-342 Mid Tower ATX Computer Case - High Airflow, USB 3.0, Black - Perfect for Gaming PC Builds & Home Office Workstations

Your Cooler Master 400 watt installed power supply was BAD, the +12 volt supply was only +10.7 volts, which crashed my Windows operating system. I do not think Amazon.com and Computer Headquarters Certified Refurbished can send their customers DEFECTIVE components without any recourse. Your lame excuse to avoid replacing this bad power supply is unacceptable. My Cooler Master RC-342 Computer Case order included this Cooler Master 400 watt power supply. Amazon.com or Computer Headquarters Certified Refurbished should honor their warranty.
