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 AX1600i
9 / 10 Expert Rating
Still the digital-monitoring benchmark for extreme multi-GPU and workstation builds, docked slightly for lacking a native 12V-2x6 connector.
