Tests
We will be testing the Real Power Pro 1000 against a power supply that we have no previously reviewed in the Enermax Galaxy 1000. We would have liked to review the Galaxy 1000, and we certainly hope and plan to in the very near future, but our time with the unit was extremely limited on this date. We also initially planned to test the RPP1000 against the PC Power & Cooling Silencer 750 EPS12V, but we ended up choosing not to, for reasons we will get into in just a second.

Since the Enermax Galaxy 1000 was already installed in the system, we started there. The Galaxy 1000 is a modular power supply, and as such the +12V rails are somewhat ambiguous. We tested what we believe to be 4 different +12V rails on the Enermax Galaxy 1000, based off of the modular plug labels and locations



As you can see, the Enermax Galaxy 1000 performed very well, dipping below the nominal voltages only once during testing. While the measurements could be considered “high”, they are not higher than the values we have recorded for any other power supply we have tested in the past. Furthermore, the fluctuations we observed in between different testing scenarios were minimal. Also note that the total power consumption of this system was 961 Watts under full load. Had we overclocked the system by about 10%, these power supplies would probably have had a difficult time keeping up. We weren’t really interested in frying thousands of dollars worth of hardware, so we opted not to overclock in the end. We plan to one day be able to load power supplies beyond their rated capacity to see if, when, and how they fail, but for now our budget prohibits such activity.

We swapped out the Galaxy for the RPP1000 in a little under 5 minutes, most of which was spent removing the Galaxy. The RPP1000 is very easy to install because it is quite small in spite of its tremendous rated output. In comparison, the incumbent Galaxy is a much longer unit. There are also plenty of cables for even the most advanced system. Before actually getting the test underway, we traced all of the +12V leads from the PSU’s PCB to the end of each cable. By doing this we were able to identify all of the different +12V rails, which allowed us to test each individual rail. It turns out the division of these rails is pretty logical; one rail shoots straight to the motherboard, another goes to the EPS12V connection on the motherboard, one supplements the MOLEX connectors, two of them provide juice for the PCI-E connectors, and the last is kind of split between SATA and MOLEX connections. At least, that’s what we gathered by tracing a bunch of tiny yellow wires through a bunch of other tiny yellow wires and red wires and orange wires and black wires…



As you can see, the measured voltages appear to be a bit higher than what we would have preferred. However, they are still within accepted range. You can also see that the different +12V rails had slightly different realized voltages, but that the fluctuations were essentially the same. Rail fluctuation under different operating scenarios is the main thing we look at when evaluating a power supply as opposed to the accuracy of each individual rail. Based on this, it is fair to say that the Real Power Pro performs exceptionally, as the maximum fluctuation we observed was a mere 3 hundredths of a volt. In contrast the maximum fluctuation we observed on the Galaxy 1000 was 5 hundredths, slightly more than the RPP1000 but still rather good.
