Common be quiet! PSU Pitfalls
- Underestimating cable stiffness. be quiet!’s cables are thicker than Corsair’s and harder to route in tight cases. Plan cable runs before installation.
- North American availability. Dark Power Pro 13 stock is intermittent in NA. Plan to order from Newegg or Amazon when in stock rather than waiting on local retailers.
- Warranty registration. The full 10-year warranty requires registration on be quiet!’s website within 30 days. Default coverage is reduced.
- Older Dark Power Pro 12 stock. Some retailers still have non-ATX 3.1 Dark Power Pro 12 units. Verify the “13” model number before buying.
- Mixing with non-be quiet! cables. Pin configurations differ. Never use Corsair or Seasonic cables with be quiet! PSUs.
Frequently Asked Questions

Final Take
be quiet! is the audiophile’s PSU choice. The Dark Power Pro 13 is the quietest flagship PSU on the market and my pick for the ultimate silent RTX 5090 build. The Pure Power 12 M 850W brings that acoustic philosophy to mainstream prices and earns a strong recommendation against Corsair RM850e and Seasonic FOCUS GX-850.
