600-650W power supplies review: 46 models compared

Taking a look at the 'sweet spot'

By


Efficiency

The three most efficient power supplies are the Seasonic Prime Titanium, Enermax Platimax DF 600W and the Be quiet! Dark Power Pro 11 650W, with an average efficiency of 92.9%, 91.9% and 91.1% respectively. Note that the Silverstone Strider Titanium 600W with 90.8% efficiency ends up in fourth place behind the Platinum-power supplies of Enermax and Be quiet! This shows that a certificate does not necessarily mean anything. The Seasonic and the Silverstone power supply do not reach 96% efficiency that Titanium imposes at 50%. However this is presumably caused by the fact that our test structures the load differently (and more realistically) than the 80Plus group.
