    No complaints here and I have been using it daily for a few months now. Going strong the same as it was fresh out of the package.

    It Powers my build and so far no problems at all. Cables can be a bit more of quality but it gets the job done.

    Goes in the A tier list of Power supplies that Linus Tech Tips has included. Got it for a heavy discount on Prime Day and just could not say no to it at that price point.

    Love the psu. More than enough for a simple build. Modular design enables you to put exactly what cables you need, making cable management MUCH easier and cleaner.

    I ordered this to install in a recent PC build, and I could not be happier with this product. I use it with a meshify C fractal design case and was very pleased that the PSU integrated and installed seamlessly with another brand. The screws all lined up correctly and it fit inside my case like a glove. I love that the fully modular design, it helped to make cable management and extension installation very easy! I really like that if I’m not using the cable I could just leave it out. I also liked that the noise and heat levels for me personally are very low. I have 6 case fans and those are louder than anything- when the fans are off I don’t even hear the PSU fan. Temps stay about 3 degrees Celsius warmer than the rest of my computer as well. As far as Corsair Icue it is supposed to be hooked up and synced but I don’t use the software for the PSU, mostly just checking temps. Other than that a fabulous PSU, love that it comes with high quality cables that do not feel cheap either. If I didn’t want to switch out the PCI cables for colored ones I would have 100% used these; and the cables that are not exposed are still running the OEM cables. I would 100% recommend this because of the quality, functionality and price.
