Testing (continued):

Further testing was performed using OCCT, a utility that can monitor the various voltages (with the help of Everest Ultimate Edition 4.0 in this instance) as it stresses key system components.


OCCT can monitor a variety of system information as it runs, including voltage data, and in the end it generates its own charts to summarize the findings. As shown in the charts below, the 3.3V and 12V rails were perfectly stable... No ripples at all during the 30 minute stress test!


The 5V rail had a total ripple of 0.01V (or 0.31%), and it was only experienced at one point during the 30 minute stress test.


The final tests are fairly subjective. Taking the noise level into consideration, the dual 80mm fans in the Tagan ITZ 1300W PSU produced a slight hum which was noticeable over all the other fans in a Lexa Blackline case, which included an eVGA 8800GTS OEM cooler. The air from the exhaust of the power supply seemed warm, so I took a look at the effect it had on the room. With the system turned off, the ambient temperature was 22.5 degrees Celsius, but after the system was powered on and running for 60 minutes in the load condition described above, the ambient temperature rose to 23.6 degrees Celsius.
