Robust DC-DC conversion
For clean, consistent power, each CX-M Series power supply features robust DC-DC conversion and 105°C rated Japanese primary capacitors for unparalleled reliability.

Compact size
At just 140mm long, the CX-M Series offers great flexibility in build configurations.

CERTIFICATIONS
The Cybenetics organization measures efficiency and noise levels across the PSU’s entire operational range, using more than 1,450 different load combinations.

The "Bronze" efficiency rating is defined as >=82% & <85% (depending on input voltage).

The "Silver" efficiency rating is defined as >=87% & <89% (depending on input voltage).

The "S++" noise level test is measured in those same configurations to be ≥30 dBA & <35 dBA under noise data averaging.
