Result Summary

The TITAN PLA 1000 W has passed all our tests with zero issues. The fan profile presented in the diagram by MONTECH very closely resembled our testing (albeit, the fan began spinning not at 30 %, but at 40 % of the unit's rated power output). What's even better is that the noise output till the very last overload test was barely audible, making the acoustic performance a very strong upside of the TITAN PLA 1000 W. In terms of power factor correction the unit performed average, while the voltage regulation for the +12 V rails looks very strong.



Technically in our setup the TITAN PLA 1000 W barely misses the 80 Plus Platinum mark at 50 % load (by less than 0.3 %). However, the overall efficiency is great, matching the 80 Plus Platinum requirements without issue. The efficiency stays high even at low loads, reaching >90 % already at 10 % load and remains very high with a more observable decline at the 80 % load mark. But even at 110 % output the PSU is able to operate at >90 %. This is precisely why measuring the efficiency at a more granular scale (not just at 20, 50 and 100 %) is so important to have a better overall grasp of the PSU's performance.

Voltage Regulation

The voltage regulation is especially solid for the +12 V rail. We see overall a very flat line across the entire load range and very well handled output at even the highest loads. The +5 V output also looks very respectable, with the +3.3 V rail performing quite average, still well within the ATX specification.

Ripple

Ideally you want the DC voltage delivered by your power supply to be a completely flat line when looking through an oscilloscope. However, due to the switching nature of ATX power supplies and the less than ideal real world behavior of all the components involved, we get very small fluctuations in output voltage known as ripple and noise. The ATX spec allows for ripple of up to 120 mV for the +12 V rail and 50 mV for the minor rails.


Very solid performance from the TITAN PLA overall, with ripple well controlled even at high loads. The oscilloscope waveform output of the 110% load test can be seen below.

Short Circuit Protection

Short circuit protection is one of the most fundamental and important protections for a power supply. If a short circuit is detected on any rails, the PSU should turn off to prevent damage to itself and other components.


SCP worked as expected with the unit.
