Zumax 950 Watt X4 Review

Testing:

How will I know if this power supply delivers the watts? I need to test how it performs under load, verifying the voltages and airflow. With that being said, we can finally start testing the unit. To put this power supply through its paces, I will run a series of tests to load the Zumax X4 950 to simulate heavy gaming usage . The testing procedure will include running Stressprime 2004 Orthos Edition to stress the CPU and memory, HDtune to load the hard drives, and 3DMark06 Professional to stress both video cards. The test system includes five high CFM Silverstone fans to add additional load to the 12volt line. Additionally, I will check the airflow at both idle and load conditions to verify any increase in airflow through the rear of the power supply. Voltage measurements will be taken with my trusty voltmeter, while airflow will be tested using my Kestral 4100 pocket airflow tracker.
