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.
FSP Hydro K PRO 750W
7 / 10 Expert Rating
A solid 750W Bronze-rated ATX unit for a popular RTX 4070 Ti / RTX 5070-class gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
