Verdict
be quiet! Pure Power 12 M 850W
8.2 / 10 Expert Rating
The 850W Pure Power 12 M tops out the modular M-series, giving budget-focused builders a native 12V-2x6 connector and Gold efficiency without stepping up to the pricier Straight Power line.
Seasonic Focus GX-650
8.3 / 10 Expert Rating
A solid 650W Gold-rated ATX unit for a mainstream single-GPU gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
