NZXT Precise 1000W Power Supply


Testing Continued:

Now we'll test the voltage while the system is under load.  The test setup is exactly the same as the test at idle, except that I will run one instance of Orthos Version 0.41 set at small FFT's to stress the CPU, and simultaneously run 3DMark06 to stress the 12VDC video card.


In the charts below, as in the zero load charts, I've plotted the results for the Precise 1000W and the results for the OCZ GamerXstream.

The results here show that the voltage regulation for the Precise 1000W is extremely good.  The difference between load and zero load is so small it can't be seen on our graphs, so I've put them on a chart for illustration.  The variation from zero load to load on all voltages is as follows:

Voltage % Variation
3.3VDC 0.38%
5.0VDC 0.59%
12.0VDC 0.33%

With this kind of stability, this PSU should be able to supply all that the hard core systems will demand.
