Verdict
be quiet! Pure Power 12 550W
7.8 / 10 Expert Rating
A quiet, Gold-rated 550W unit that's the right call for mainstream builds that don't need full modularity.
Corsair SF1000L
8.2 / 10 Expert Rating
A rare 1000W SFX-L unit that fits mini-ITX builds pushing an RTX 4080-class card, and the native 12V-2x6 cable means no clunky adapter stuffed into a cramped case.
