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: Double-sourced between FSP and HEC. FSP provides the 1200W variant for the US market and HEC supplies it for the European market. Good noise profile and electrical performance. First be quiet! PSU with semi-passive operation.

↪ 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: 85C bulk cap, rifle bearing fan. Good noise profile. The OCP triggering points on the minor rails are set much higher than necessary.

↪ 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.
