Tuniq Ensemble 1200W Review

Testing:
The old way of testing power supplies with a wing and a prayer is no longer sufficient in the tech savvy world we live in. People want to know just what kind of power a supply can actually deliver and still conform to the ATX specifications. With a new testing methodology, OCC will move into the future to provide a more current testing regime, to accurately show how a power supply performs.

Short Circuit Protection
Quote: "When any set of DC output is in short circuit, the power supply shall be latched into the status of shutdown in order to protect the circuits and component from being damaged."
In order to test this claim, I short circuited the 3V3, 5V0 and all four 12V lines in turn. The power supply did shut down and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end in case it doesn't quite go to plan.
DC Output Voltage Load Regulation
I had initially planned to list the results at three different load levels but by the time I had finished my testing, I had five sets of results at 17, 39, 53, 64 and 95% of specified full load. Here are all five:

Total Load at 173W which is 14% of Rated Maximum Output Power. |

All the DC outputs were held within the ATX12V specification at all load levels and I saw no voltage fluctuations during the load testing. The three main power lines, 3V3, 5V0 and 12V are of particular interest and ability of the power supply to maintain these at an optimum level is important for the reliable operation of your PC. If you are going to push your PC (overclock) they become even more critical. Ten out of ten so far.
