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.

what is 10% when the consumption is low?Also the 80plus certifications are created to take into account that the best efficiency is achieved at certain loads.
This is why they have certifications instead of a single efficiency number.
The consumer gets the information on efficiency synthetized in a single artificial indicator.

What, you are going to complain about 5w? On a 'normal' PSU you would be looking at 50-60% efficiency at such low loads.HOOfan 1 - Thursday, October 8, 2015 - link
Not sure what you mean by normal. No PSU worth buying on the market today is going to be that inefficient at 50W draw.80 Plus Titanium calls for 90% efficiency at 10% load, so at 50W, this unit should be 90% efficient. None of the other 80+ Certifications specify efficiency at 10% load.
Using Techpowerup, here are some numbers for 80 Plus Gold units.
Seasonic G550 84% efficient at 59W draw retails for $80
EVGA Supernova G2 650 84.77% efficient at 59W draw retails for $100

I don't think you know how to reach charts.http://www.anandtech.com/show/9663/the-andyson-n50...
At 50W rating, the power efficiency is >90%.
It seems you also didn't even read the review:

@ 10% load it's 91.4% to be precise.
Next time before trying to criticize a product, maybe you should actually read the review.

Are you replying to me or Shadowmaster? I was correcting Shadowmaster when he said it was only 85% efficient at 44w by saying it was at least 90% efficient at 50w. Then I corrected Caedenv when he said other PSUs are only 50% efficient at that losd. So basically if you are refering to me then you just backed up what I already posted...DanNeely - Thursday, October 8, 2015 - link
Actually it is. At idle loads a 80+ Gold PSU would be about 75% efficient; Titanium is the first standard to set a 10% efficiency requirement at all. Squeezing a tenth of a watt of consumption out of fixed power components is much harder than trying to get a tenth of a percent improvement at high loads.DzanZeMan - Thursday, October 8, 2015 - link
Actually, 84.6% effeciency at 5% (27.5 watts) and 91.4% effeciency at 10%. details... details... amirite?RussianSensation - Thursday, October 8, 2015 - link
Exactly. The guy goes off criticizing the product when in the review's description and in the charts it's as clear as can be that at 10% load efficiency is at least 90%.ShieTar - Friday, October 9, 2015 - link
Almost "rite". Its a 500W unit, so 5% are 25W, not 27.5W.Nitpicking, I know ;-)

Anything over 80% efficiency at <10% load is excellent.85% is unbelievable. As an electrical engineer I can't even wrap my head around how efficient that is. The analog ballasts and transformers I'm used to working with are usually around 70% efficient at idle\no load state. Even a Class 5 transformer to charge your phone saps around half a watt hour without a load, and since those devices are typically 3w, that's about 80% efficient and as good as consumer electronics often get.
