    Love that it comes in white with white cabling. Although you cant see it under the basement of my case, it still helped with my color theme. Great power and dependable.

    Bought this to pair with a new i5-12600K CPU and MSI Z690 Force Mobo. Cant hear it at all and it looks super clean. Cables are well made but are SUPER stiff, the 8pin cables are the pigtailed ones. If you want a cleaner build I would recommend buying extensions. Overall its a great PSU.

    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.

    Ordered one to fit into my system to use my new 3080 and I (foolishly) installed it before testing it. Turned out it wouldnt power on at all. Tried replacing it and the replacement had the same issue.

    When I finished the build, on bootup the PSU had a ringing noise. I was upset that it could be a bad bearing. But be caution that the wires inside actually gets caught on the fan. Make sure nothing touches the fan blade before install.

    It’s great for saving energy and it only turns on fan if needed if to warm and good for the price
