Evaluation & Performance (Cont.)

To finish of the performance analysis I took the liberty to run a comparison between my old Ultra X-Connect 500W and the Hiper Type-R 580W power supplies. Both PSU's ran during 1 hour in idle configuration, meaning just power up and doing nothing and in full load operation. During full load we used two applications to get both CPU and GPU running at full speed. This was done by using RC5-72/OGRp2 Distributed Client that will use all available CPU processing time to crack a 72-bit secret encryption key. On top we ran Futuremark 3DMark05 in loop mode to let our PNY Verto 6800 GT run at full occupation to maker sure also the GPU is balancing out the power usage drawn from the PSU.

Ultra X-Connect 500W - Summary Table

	Minimum		Maximum		Average
Voltages	Idle	Load	Idle	Load	Idle	Load
CPU Core	1.33V	1.28V	1.38V	1.32V	1.37V	1.29V
+3.3V	3.31V	3.28V	3.34V	3.34V	3.33V	3.31V
+5V	5.08V	5.08V	5.13V	5.16V	5.11V	5.11V
+12V	12.22V	11.98V	12.40V	12.16V	12.28V	12.06V

When looking at the above summary table on the reported voltage from the X-Connect 500W from Ultra we can see one dip. Indeed the +12V rail drops actually below 12 volt which is rather strange and although is just minor below the 12V margin it is certainly an indication. On the average level this PSU has a very good performance level.

Hiper Type-R 580W - Summary Table

	Minimum		Maximum		Average
Voltages	Idle	Load	Idle	Load	Idle	Load
CPU Core	1.30V	1.28V	1.38V	1.32V	1.37V	1.30V
+3.3V	3.38V	3.31V	3.42V	3.46V	3.41V	3.39V
+5V	5.08V	5.03V	5.13V	5.16V	5.10V	5.10V
+12V	12.10V	12.04V	12.28V	12.28V	12.19V	12.14V

Next is the Type-R 580W from Hiper that puts down even more impressive results. By just checking over it the summary table we can't spot any dip on the voltages. That alone makes it already says enough, the voltage levels are kept and remain above there nominal values. When looking at the average results we are quite impressed. Almost all voltage levels remain quite stable between idle and full load state.

Comparing the Ultra with the Hiper power supply show us that the Type-R 580W is better performing at all levels. At full load stress testing the Hiper didn't show any dip on voltage and performance levels, which can't be said from the X-Connect 500W. So on in all the Hiper Type-R 580W does what is says and delivers stable voltage even under heavy load. Well done Hiper!
