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.

NZXT C1000 Gold

8.3 / 10 Expert Rating

A solid 1000W Gold-rated ATX unit for an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
