    Verdict

    be quiet! Pure Power 12 M 750W

    8.2 / 10 Expert Rating

    A solid 750W Gold-rated ATX unit for a popular RTX 4070 Ti / RTX 5070-class gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.

    Seasonic Core GM-650

    7.6 / 10 Expert Rating

    The cheapest legitimate route to 80 PLUS Gold in Seasonic's lineup, good for mainstream builds that don't need full modularity.
