Cold Test Results

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

As expected, the efficiency of the N500 Titanium is astonishing. The unit reached a maximum conversion efficiency of 95.2% at 50% load and an average of 94.1% within the nominal load range (20% to 100% of the unit's capacity). Not only that, but the low load efficiency is comparatively excellent as well, with the N500 Titanium maintaining an energy conversion efficiency of 91.4% at 10% load and 84.6% at 5% load. An efficiency greater than 84% with a load of merely 27.5 Watts on a 500W unit is outstanding.

The very high efficiency of the N500 Titanium aids its own thermal performance, as the PSU does not have to dissipate large amounts of heat. Generally, the internal temperatures are low, just not as low as one would expect from a 500W unit with 80Plus Titanium efficiency. If not for the very small heatsinks of the PSU, thermal performance figures could have been even better. Still, the temperatures are low enough to keep the fan from spinning too fast. Even with the PSU at maximum load for prolonged periods of time, the fan will barely be audible outside of a PC case.

    While well within spec, the ripple suppression on this unit is not very impressive.
    Using numbers from the EVGA Supernova G2 550W easily beats this unit on load regulation and ripple suppression, for $20 less.

    Saying that, the Andyson N700 Titanium tested got load regulation and ripple suppression numbers which equaled or bested the EVGA Supernova.

    You really shouldn't compare reviews from one reviewer to another when the results are this close. Different test equipment and testing methodology will result in slightly different findings. Reply

    You said the magic word "slightly" so what he is talking about is most probably true. Reply

    Season are built like god damned German tankers. Best money I ever spent, probably my longest lasting PC part I've ever purchased. Reply

    agreed. even with its 7 year warranty, i expect to keep my 750wt Seasonic platinum for atleast 15-20 years. What PC desktop part lasts that long??? Reply

    And how loud is that EVGA unit according to techpowerup's review? That's the thing people so often neglect to mention when bragging about those units. Reply

    I haven't looked at the review of the 550W unit but I remember 48 dB for the 750W unit at 600 watts, and 48 dB for just 300 watts and above with the 850W unit. Reply

    Actually more like 350 watts for the 850W unit. But, still... that's bad acoustic performance. Reply

    So, 85% efficiency when my machine is idling and consuming 44W? I dont know, that doesnt seem very good. Reply
