Cybenetics is officially recognized by Intel, starting from the ATX v3.0 specification. This is one reason that Cybenetics has been pushed to run even more tests on each PSU that it certifies to check if it meets all the requirements of the ATX v3.0 and ATX v3.1 specs, including the transient response tests (or PSU Power Excursions, as the ATX spec calls them), which can reach up to 200% of the PSU’s max power for over 450W PSUs or those that don’t have the 12+4 pin connector.

Cybenetics conducts many tests to check for ATX v3.x compliance, including PSU timings, DC Power Sequence, efficiency at 2% load, inrush currents, load regulation, ripple suppression, turn-on overshoot, and more. Generally, if the PSU doesn’t meet the ATX v3.x requirements, it doesn’t get an ATX v3.x Pass badge. The most challenging requirement so far proved to be the transient response tests.
