    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!

    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.

    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.

    Ok, so maybe it was a little more than I needed but it's better to have a little extra wattage available than risk be under powered. More than plenty of ports and not much difference in price when compared to lower wattage options. Easy to setup and runs very quietly.

    It seems to be a great power supply for the price, and it looks good in the computer I'm building. Black ram, black PCU, and black graphics card. Looks sharp, powerful, and works so far. It comes with everything you need. Plus there's a nice bag for all the cables. If I have any complaints, it is that the cables are really nice, but they don't bend very well. Cable management is interesting.

    Robust and durable build quality and slots perfectly into my full ATX Tower case. Modular cables are a must and are a good length to thread through the case as well with plenty of extra watts and a hardly noticeable sound. I would highly recommend

    This was the only PCI 5.1 PS in stock and works great. I would purchase again, but don't need a modular PS. Now we know to plug every cable into the PS before inserting it into the Cosair 4000D case due to crammed space in case. This is actually the 2nd time we purchased this PS because again, it's the only PCI E 5.1 PS in stock and we want to use it with a NVidia RTX 50 series card.

    This psu has been recommended by many and just like them, I urge anyone that is browsing to get this one!! The unit itself is capable of dishing out enough power for any budget range, beginner-high end, and realistically there isn’t a need to upgrade or change.

    I replaced my old 750W Skytech PSU that I thought it was 650W with this one. I can tell that the performance of this PSU is really amazing, and it is silent even while gaming.
