The Jeantech Arctic JN120F-600AP12V2 obtained average results in the Stress Test.

The graphic above shows the power supply connections and their length in centimeters. SLI option is available; SATA connections are too spare.

Features

Jeantech glistens with a special feature. The manufacturer equips its power supply unit with three voltage sensors which measure the voltages on the 12V, 5V and 3.3V strands directly on the ATX connector on the motherboard and if necessary adjusts them. In this way, the manufacturer hopes to counteract any voltage drop on the ATX feeder. Another positive note is that the different cables can be pinned or unpinned. This way the user can reduce the cable spaghetti inside the case to only the most necessary. However, the manufacturer could have thrown in more than only two SATA connectors - this is clearly too few for a power supply of this power class.

Jeantech presents itself black as the night. In contrast the 120-millimeter fan shimmers completely in white through the venting slits.

Dangerous for the die-hard modders who would like to use the hot Plug'n'Play functions of serial ATA: The contact pins of these S-ATA jacks stick out and can easily be short-circuited in operation if you accidentally touch them with metal pieces.

In addition to the supply voltage jack, the internal cooling mode can be set: H A L stands for High, Automatic and Low. For the test we're using the Automatic setting.

Test Results

The manufacturer Jeantech had a few thoughts and directed his attention toward high stability and good voltage values. As our THG live stress test shows, the voltage sensor that the manufacturer installed was well worth it: Under full load with 600 watts, the 12 volt bar of the CPU was at exactly 12.01 volts and the other values were also all within specifications. Even with the loads fluctuating, a stable voltage supply was always provided to the CPU and components.

Thanks to the large 120mm fan, the rotational speed is low and the power supply has a comparatively low operating noise, even under high load.
