In The Box



When you crack open the seal of the box you'll be greeted with the normal accoutrement of goodies, but there are also a couple of extras that you might not be used to seeing with a power supply. The standard stuff consists of the PSU, the power cable, a small manual and some mounting screws. But what about these little extras?



First off is a couple of adapters. The short one you'll probably recognize as a 24 to20-pin converter. This is good news for those running the newer motherboards since there have been some issues with using a 20-pin PSU and using an adapter for the 24-pin mainboard. From past boards I've tested, however, there have yet to be any issues with the reverse, so if you're still using a 20-pin mainboard, the adapter will work just fine and you'll not have any stability or power issues.


While I have tested Seasonic brand power supplies in the past and am accustomed to the main power adapter, the other one shown above is something new to their list of toys. The larger end is a standard 4-pin Molex connector that hooks directly into one of the Molex connectors of the power supply. This branches off into three individual adapters for use for those fans that still have the older 3-pin power connector. But that isn't all that this small converter is capable of. If you'll take a look closer, you'll see that two of the connectors are red/black and have a different pinout than the remaining yellow/black connector. Those who have worked on self-made fan speed connections will already know the significance of this difference.


The two sets of cabling with the red/black coloring are only pushing 7v to the fan hooked up to it. The yellow/black colored one is running a full 12v to the fan. The reasoning behind this is for noise control. While this may be a good thing for those with a standard system, those who are serious about overclocking may not want to utilize this feature. If not, then just leave the connector in the box. A final note regarding this device... it is not advisable to use the 7v ports with lighted fans. LED fans tend to get testy when they are not allowed to run with a full power level and the lighting will often be adversely affected.



The next addition to the equipment list is called "Dr. Cable". Some have seen this before, but for those who haven't it is a cable management device for the beginning enthusiast. There are two sizes of split plastic tubing that can be wrapped around wire clutter and cut to a proper length. From there it is a simple matter of using the enclosed zip ties to secure the wrapped wiring harness to a side of the enclosure framing. We all know that when you keep cable clutter to a minimum, you get better airflow within the enclosure. This is a simple yet effective means of addressing the problem of messy wiring in your case.
