    Fully modular and works like a charm. It was about time to upgrade my psu and this had felt like a great choice, especially if a member deal comes around.

    First one was faulty and had a bad bearing within 2 weeks of purchasing. Second one has been quiet and worked well so far. 5 stars if I did not have to replace it so quickly.

    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.

    This may be my new favorite power supply. Was easy to install and no need for a bunch of cables crammed in that you don't need only use what you need.

    Powers up my PC perfectly. Have a 7800X3D CPU and 7800XT GPU and have plenty of power to spare. Completely Modular and has 4 PCIE ports. Highly recommend for mid range PC builds.

    MSI 850W Modular Power Supply

    The power supply met the needs of my new build and was a reasonable price or an in person, need it right now, buy. It was easy to locate in the store and the product itself was relatively easy to figure out (I'm rather new to fully modular power supplies, so I had a little learning curve on my end.) All the pieces were present in the box and the staff were fast and helpful.

    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.

    good psu, not loud

    I was a bit hesitant to buy this PSU because other reviews claimed it had a rather loud fan. Fortunately, I found the fan to be nearly silent - certainly less loud than the fans already installed into my computer case. The cables included are quite long, so have some plastic ties available to help with cable management. For full ATX or E-ATX builds, this is a fine pick.

    Really easy to put together. Although this was a purchase primarily due to my battery being old, and I just needed a quick replacement, this battery is acuatually amazing. Instructions were great too, just don't be like me and have a weird casing for my PC. Besdies the purchase, the best buy i got this from was cool.

    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
