Initial testing of the Tagan ITZ 1300W power supply will focus on determining whether the main voltage rails (+5V, +12V, and +3.3V) fluctuate from idle conditions to full load conditions using a Craftsman Auto-Ranging Multimeter (Model 82139) to monitor all voltage readings.
The idle condition was established by powering the system at default speeds and voltages with no applications running for a period of at least 30 minutes. The load condition was established by running Folding@Home and Sisoft Sandras Burn-In Wizard for a period of at least 60 minutes.
For comparison purposes, the Tagan ITZ 1300W unit was tested head-to-head with two other high end units, the 1000W Ultra Products X3 and the 1000W OCZ Technology ProXStream.
While using a multimeter, results are only valid at the exact instance that the reading was taken, so I left the multimeter connected to each rail for several minutes and monitored it for any fluctuations. During each of the tests no fluctuation in any of the power rails was noticed. However, the 5V and 12V rails were putting out slightly less than the official rating, while the 3.3V was putting out a little more than the official rating. Each of these differences is well within the 5% tolerance level.
