After a discussion on the hwbusters discord server, I decided to make this brief article, showing you the eight more efficient PSUs that I have evaluated so far. These units are at the top, achieving a sky-high overall efficiency.
Unlike 80 PLUS, Cybenetics applies >1450 different load combinations, from close to zero to full load. It uses the average efficiency reading in its ETA certification to tax the PSUs into one of the six efficiency categories, starting from Diamond and with Bronze as the entry level. Currently, there is no Diamond-rated PSU since the bar is too high at this level, requiring ≥93% overall efficiency at 115V and ≥95% at 230V.
Commenting on the FSP Hydro Ti Pro 1000W PSU review, a member of the server wondered if this was the most efficient PSU that we have ever tested so far, so I thought it would be nice to provide you with a short article showing you the most efficient PSUs that we have ever encountered so far. The Cybenetics team has managed to evaluate several thousands of PSUs all these years, building an enormous database, and it is always interesting to exploit this huge amount of data.
The following charts will provide you with the eight PSUs that achieved the highest efficiency scores at 115V and 230V. Since these results are by the Cybenetics labs, I will honor the effort of the entire team and will use Cyben’s logo instead of the HWbusters one.
The Wentai Aidan T1616 leads the race with its digital Totem-Pole bridgeless PFC and full-bridge topology. Next comes the Seasonic Prime TX-1600 with a bridgeless, interleaved PFC and a full-bridge topology. The FSP Hydro Ti Pro comes third, with a bridgeless PFC and a full-bridge design.
At 230V, the Seasonic Prime TX-1600 takes the lead, with the FSP Hydro Ti Pro 1000 following closely. The be quiet! Dark Power 12 750W is only a hair away, using an FSP platform.
