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.

Oh, and the word is "strove", or "have striven" - not "strived"etamin - Thursday, October 8, 2015 - link
What's the warranty on this? I don't think it was mentioned in the review.CaedenV - Thursday, October 8, 2015 - link
Nice, the PSU in my home server is ~10 years old and in need of replacement. This might be the perfect thing for an always on device with a bunch of HDDs.Madpacket - Thursday, October 8, 2015 - link
Now someone needs to release an SFX version and I'll be all over it.JanW1 - Friday, October 9, 2015 - link
I may be missing something obvious, but why are the tests on this unit performed with 100% corresponding to 550W? Shouldn't the 5% load test have been performed at 25W for example?KAlmquist - Friday, October 9, 2015 - link
I'm guessing that the reviewer made a mistake when selecting the loads used to test this unit, and didn't want to go back and do more testing when he realized the mistake.nem3sis - Friday, October 9, 2015 - link
where i can buy this PSU in America..? =)nem3sis - Friday, October 9, 2015 - link
here i found a guy than made an group to buy this psu since Taiwan hope someone join us.. =)https://geekhack.org/index.php?topic=73710.0

I've had my modular Thermaltake 80 Plus 850 watt PSU (rebranded Seasonic) now for almost 8 years I think. Can't go wrong with a Seasonic, buy once and never buy again.chipped - Saturday, October 10, 2015 - link
In other words, just get a Seasonic and screw the rest :P
