Recently purchased the Corsair Commander Mini fan controller. Neither came with the needed adapter to work together. From what I read the adapter would plug in from the PSU to a USB 2.0 header on the MoBo. I don't have any USB headers left for that and the adapter is bulky anyway. So I passed on that. The PSU is fairly shielded and and air intake and exhaust is as well. It can manage its fan control on its own so it is not a big deal or necessary that it is connected to the fan controller anyway. Other than that I have been extremely happy with this PSU. It would have been nice is the cables were a bit easier to bend for routing and stowing purposes (a bit stiff) but it is probably a good thing they aren't making them harder to bend too much and break.

Great PSU, no issues.

$180 of my budget was quite a lot for a PSU, however I do not regret purchasing this Corsair unit at all. I could easily have spent under half that, but to me cheap PSU's are a false economy. The highlights for me are the fully modular cables, which are all black and of the ribbon type. Very easily to manipulate around the case, and look the part too. I did find using the SATA cables a struggle, but this was due to the case having the SSD's side by side rather than in a traditional stack. To my knowledge, the fan never turns on so there is no noise at all. In my rig, I was able omit the GPU and Molex cables which resulted in a lot less cable clutter.

No Problems, fan doesn't spin in this system, pretty much ever. Dead silent.

Corsair Fully Modular is the way to go. 550W was a great choice as it's a healthy medium for wattage

The cables are all black, its corsair quality and is super quiet. The fan only turns on when it needs to.
