The Sentey Golden Steel Power 850W power supply didn’t quite hit the required 80 Plus Gold levels for efficiency following the OCC power supply testing methodology, but this is usually the case. The 80 Plus tests are done at predetermined DC loading levels on all the rails that I just can’t match exactly, but with a peak efficiency of 89%, just 1% short of the mark, it’s a pretty good result. Power factor levels aren’t a problem, but this is usually the case when active power factor correction is implemented.
