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.
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.
