be quiet! Power Supplies

↪ Notes: Not to be confused with the downgraded non-modular Pure Power 12!

↪ Notes: Bridgeless PFC, OCP needs tuning on all rails

↪ Notes: Excellent noise profile.

↪ Notes: Bridgeless PFC, very high component and build quality. OCP needs tuning on all rails. Excellent noise profile.

↪ Notes: Excursion response in the 200% test could be better compared to other units in its class. Excellent noise profile.

↪ Notes: Interleaved PFC; digital operation for primary, APFC and 12V; minor rails are analog.

↪ Notes: Interleaved PFC; digital operation for primary, APFC and 12V; minor rails are analog.

↪ Notes: Custom be quiet! rifle bearing fan.

↪ Notes: Non modular variant of the Pure Power 10 CM, virtually identical.

↪ Notes: Weak 3.3V transient response, mediocre electrical performance, and claimed rifle bearing but yet to be proven.

↪ Notes: 85C bulk caps, excellent noise profile.

↪ Notes: First be quiet! PSU with semi-passive operation.

↪ Notes: Low quality fan, 85C bulk cap.

↪ Notes: Terrible ripple suppression, especially on 12V (well over 100mV under full load), OCP is not set properly, low efficiency, low quality fan.

↪ Notes: Looks exactly the same as the regular System Power 10 internally. Unless later testing proves the above issues are not present, detier to E.
