be quiet! Pure Power 12 M 750W vs Corsair RM750e: which one fits your build
The be quiet! Pure Power 12 M 750W is the one to take for anyone who wants fully modular cabling with native 12V-2x6 support and systems where a 5-year warranty and Gold-tier efficiency matter, though it is not the pick for builds needing more than 750W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint. It also earns its place with builders targeting a popular RTX 4070 Ti / RTX 5070-class gaming build. The Corsair RM750e suits Quiet builds where fan-off idle and light-load silence matters and single RTX 5070 Ti-class GPU builds on a budget, though it is the wrong buy for RTX 5080 or 5090 builds, wattage isn't enough. It is not the one for RX 9070 XT builds needing 3 PCIe 8-pin connectors without checking cable count first.

Verdict
be quiet! Pure Power 12 M 750W
8.2 / 10 Expert Rating
A solid 750W Gold-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.
Corsair RM750e
8 / 10 Expert Rating
The quietest thing at this money by a real margin, but MSI gives you a better fan, more cables and three more years of warranty for five dollars.
