Corsair TX750W 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 Corsair TX750W to simulate heavy gaming usage. The testing procedure will include running Prime 95 version 25.5 to load all four CPU cores and to stress the memory, HDtune to load the hard drives, and 3DMark Vantage to stress the video card. The test system includes five high CFM Silverstone fans to add additional load to the 12 volt 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.

Under load, the readings did not change on any of the voltages, showing a measure of stability in the rails. The fan was never load enough to be able to hear it. In fact, for once I was able to hear the D5 pump used in the water cooling loop.
