    This power supply works wonderfully! It’s a bit cheaper than seasonic when comparing the platinum series. I wanted something efficient since I do a lot of rendering, and it’s great!

    Picked this one up for my latest build, no complaints at all. Only issue I had was I forgot about the USBc connector until after the PC was built, so I did have to pull it out to get that little cable plugged in correctly.

    Even though it was way more wattage than what my pc needed, none the less it was an amazing purchase, the controls in the ICUE software are incredible.

    I loved this power supply but ended up returning it because it wasn't ATX 3.0 compliant. Ended up going with a lesser "pricier" unit. (More expensive but lower quality)

    Great piece of accessory. Measure and plan your location of power cables because it was a tight squeeze for me. (Full Tower FYI)

    Great power supply and dead silent until somewhere above the 55% load or > around 120F higher temps ,then its still not even audible until even higher loads or temps. Love being able to monitor temps, wattage and efficiency in either hwinfo or icue. Can even setup custom fan curve profiles in icue tied to your gaming profiles.
