A system that draws ~250W maximum and idles at <100W would be a good match for the 300W PSU shown above.The efficiency power curve of the 600W PSU is better suited for a system than idles at >150W and peaks at >300W. It would be a substantially worse match for the system of the previous example, as the PSU would be operating at a mediocre <75% efficiency in idle, and only just reaching 80% at peak.
From a PSU heat waste point of view, the differences are significant:
At 200W load,
* the 300W model would generate 44W of heat (18% of 244W AC input);
* the 600W model would generate 50W of heat (20% of 250W AC input).
At 90W load,
* the 300W model would generate 23W of heat (20.5% of 113W AC input).
* the 600W model would generate 32W of heat (26% of 122W AC input).

ausgeschaltet wird bei bequiet wohl heissen, das der stecker raus is oder der schalter umgelegt wurde. ansonsten sind 0w unmöglich, wie willste die kiste wieder anbekommen ohne strom auf dem taster zu haben?
