Result Summary

The performance of the Titan Gold looks very solid overall. Yes, it does not magically jump higher than its 80 Plus Gold efficiency rating suggests it will perform. But the voltage regulation is very good across all three major rails.

As for the high expectations on fan noise, those are definitely met at lower loads. The fan first started spinning at 30% load. Even up until 70% of its rated output the Titan Gold manages to remain very quiet. But after that the fan ramp up is very noticeable and quite audible. The high ambient temperatures did not manage to compromise the unit's ability to deliver even 110 % of the rated power.



The efficiency is very much on par with what you can expect for an 80 Plus Gold rated power supply. While we're barely keeping up with the minimum datapoints at 20%, 50% and 100 %, it is again very important to mention that increased ambient temperature is a significant factor in lowering the overall efficiency of a power supply. Only going above the rated power we see a sharper decline in the overall very high efficiency offered.

Voltage Regulation

The voltage regulation on all three rails is easily within the ATX spec. Even in the overload test we're only approaching the 2% deviation mark for the +3.3V rail. The regulation of the +5V rails looks especially good.

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.


The Titan Gold 1000 W has the ripple well under control. While we have definitely seen better ripple control on the +12V rail, the minor rails look very good, even at 110% of the PSU rated output. The graphs also look normal, without any lower frequency disturbances or other significant irregularities.

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.
