    5.0 out of 5 stars 10/10 A tier Power Supply with 10 year Warranty!
    Reviewed in the United States on June 29, 2022
    This PSU is an A or even S tier unit on most Power Supply Tier Lists. Seasonic know what they are doing when it comes to PSUs and have been in the game for a long long time. Fully modular, 80+ Gold efficiency, small in size to fit into nearly any case, high quality components, the option via toggle switch to enable Eco mode which turns the fan off under low load or disable it which always leaves the fan on, sleeved high quality cables, TWO EPU/CPU connectors for those power hungry chips/boards, 6 total PCIE connectors for as much GPU power as you want, several diff length sata cables, great 9/10 and 10/10 reviews by most every critic/user/tech site, and best in class 10 YEAR warranty!!! What more could you ask for in a PSU! It’s small, quiet(I’ve never heard it at all), looks good, efficient, fully modular, and has great reviews with a decade long warranty. All this with amazing pricing often less than PSUs with lower quality and much shorter warranty. You want a solid PSU behind a name you can trust that will last you a decade? Here ya go. Enjoy the pictures and thanks for reading.

    5.0 out of 5 stars Powerful, Quiet, Efficient, & Slim
    Reviewed in the United States on May 4, 2019
    I got this PSU to replace the stock 500W Bronze PSU inside my HP Omen gaming desktop system. HP had crimped on the PSU by only installing a 500W PSU into a system that came with an Intel Core i7 8700, 16GB DDR4, nVIDIA RTX 2080, 256GB NVME SSD, and a 2TB 7200RPM HDD.

    Due to a case filter on the bottom of the case, the PSU replacement had to be 140mm in length. This Seasonic PSU fit the size & power requirements perfectly. It installed easily & perfectly and I'm happy that my components are now receiving the proper amount of power they deserve.

    The PSU is very, very quiet and I can't even hear its fan even during >3-hours long gaming sessions. I also love that it is fully modular allowing for cleaner cable management & way less clutter. This is a great product.
