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 CX650M

7 / 10 Expert Rating

A solid 650W Bronze-rated ATX unit for a mainstream single-GPU gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
