    Great PSU

    If you are building a computer in late 2022 this is one of the best options for your power supply as it's future proof. This is my first MSI unit, I would have went with bequiet or seasonic but they don't have an atx 3.0 pci e 5 offering yet. So far I have no issues with my ryzren 7700x and a radeon 6900 xt after extensive gaming sessions.

    ケーブルの柔らかさと保証期間が決め手

    所有している電源の様子がおかしかったので交換用に購入しました。組み込んでから二週間ほど経ちますが問題なく動作しています。初めての12V-2x6でしたがコネクタが着色されていて、その色が見えなくなるまで差し込めば良いのがわかりやすくて良い。ZERO FAN MODEは無効にしていますがそれでも音は気になりません。ケーブルが柔らかくて配線も楽でなのでおすすめできます。
