    Came with all cables I needed for my 5070ti/9800x3D build. Also has a little baggy to hold said cables. This is a reliable PSU.

    High Quality PSU

    High Quality PSU. Just don't mount it with the fan pointing down towards the floor, as this will cause the fan to start making an awful noise after a few days. Wish this wasn't the case, as (see picture) my PC has a vent grate underneath itself and only has a small gap below the motherboard for airflow. Otherwise seems to be of very high quality and made of high-quality parts. Almost my entire PC is built with MSI parts, so that says what I think of their stuff.

    This worked great! My old one went out so I knew it was time for an upgrade, keeps a good temperature with my build and haven't ran into any issues!

    I used this in my build & is easy to set up, the best thing is that this is a PCiE. 5.0-5.1 ready. So this already has the cable for new GPUs

    10 year warranty, premium build and yellow color connection tips on 12V rail to ensure full connection to my 5080 GPU. Couldn't be happier.

    I have used this PSU in a few builds, it just works. It's modular so you only need to use the necessary cables which makes cable management a breeze. It's quiet and just performs well.

    This power supply is an excellent choice for gamers who need a good PSU. Because it is modular, you can connect only the cables you need. This helps with the appearance of your computer’s cable management. I purchased this to use with an RTX3060 12GB card in a heavily configured computer.
