    Great psu clean cables and design though not compatible with every case so make sure yours is before buying I think Corsair has a somewhat decent list on compatibility Paired with 7800x3d and 7900xt

    I was not thinking of upgrading my PC when I purchased this. All I wanted was a white theme PC. As I began purchasing parts for the PC, I upgraded from a 1080 GTX to a 5070TI GPU. This PSU effortlessly and nicely (comsetically) foes the job. It is as quite as it looks and the new cables are slim and efficient. I have zero regrets. I encourage you to purchase with confidence. Especially if your PC is white theme.

    Amazing - Love the placement of where you input the cables being on the side. I also used a Corsair Case, so it worked really well with it. Paid $139

    The shift series offers flexibility in builds. I was easily able to cable manage with ease. It depends on the case and type of space you have in the psu area. The cables included are also very clean and sturdy. At this price point this is the best money can buy. The RMX series is well built, using japanese capacitors. Which leaves me at ease when considering power surges.

    High quality power supply. The shift series works better in larger/dual chambered cases, however after a few tries it fit in an nzxt h5 flow case.

    The power supply is very heavy, sturdy feeling. This power supply does have a pretty good rating on SPL's PSU Tier List so I am pretty confident it will last. I was wanting to make an all white build for my new PC and this was the main reason I chose this one. It has black connectors on the cords so I am a bit disappointed with that aspect but the power supply is doing well so far. I have an Asus Prime RTX 5080 and I am closely monitoring the cord connection to the GPU for heat issues. So far, so good.

    I've installed this in my Corsair 3500X, and it fits perfectly. While my cable modifications make management slightly more challenging, it remains a robust and manageable power supply.

    Works as intended. Was an easy install. Only downside is I couldn’t use my existing wiring because of the proprietary corsair connections on the power supply side
