be quiet! Pure Power 12 M 750W

The Pure Power 12 M is a fully modular 750W Gold-rated supply with 12VHPWR included and a 10-year warranty, pitched at quiet, value-minded builds. As a beginner-tier unit, it keeps expectations grounded. It's enough headroom for mainstream GPUs, but RTX 5080-class and higher cards push past its comfortable envelope, so those builds should step up to an 850W-plus unit.
