Testing results (Efficiency, Noise & Thermal)

 

Being an 80Plus Platinum certified unit, the Seasonic Platinum 1000W unit delivers outstandingly but not unexpectedly high electrical efficiency. As a matter of fact, the power supply only barely meets the strict 80Plus Platinum standards, which require a minimum of 90% efficiency at 20% load and 92% efficiency at 50% load when the power supply is powered from an 110V A/C source.  

 

Despite the very high maximum power output of the Seasonic Platinum 1000W, the very high efficiency allows for the power supply to require minimal cooling without fear of high temperatures. There is barely any difference between the unit's exhaust temperature and the ambient while the system is under nominal load and the temperature delta remains less than 10°C under maximum load.

 

Fortunately, the great thermal performance of this power supply is not due to the sacrifice of its acoustics performance. On the contrary, the Seasonic Platinum 1000W unit is one of the quietest power supplies around its power output range, being entirely silent while under nominal load and becoming audible only under maximum load. Note that the hybrid fan mode did not take any effect during our testing, as the ambient temperature was above 25°C at all times.
