Chieftronic Steel Power 750W PSU Review

Ripple
Although it does appear to be an aspect of the marketing that Chieftronic has significantly played down following its initial launch, we should note that one of the original key features of the Steel Power series was it having a low ripple noise output. So, does it? Well, based on the results we found in our testing, we can perhaps understand why they may have quietly chosen to move away from particularly highlighting that one particular area.
Don’t get us wrong, the results are not bad. They were, however, so amazingly inconsistent that we can only draw one of two conclusions. Either the ripple here is not overly impressive, or our tester simply didn’t like this particular power supply (and yes, there have been occasions where that has happened in the past – and this may also explain the moderately odd results in the voltage regulation test). Taking the results as a whole, however, while definitely acceptable, we can’t personally call them low. – By our findings, ‘low’ is usually in the remits of predominantly single-digit numbers.
