Xilence Performance A+ III Series 550w PSU Review

Efficiency

Despite this only being a bronze-rated efficiency power supply, our testing provided results well in excess of that remit. At times bordering on Gold, the bottom line is that this power supply performs in an efficiency tier nearly 2 ranks higher than its official rating. This, if you hadn’t guessed, is very, very, good indeed!

I mean, look at that chart below! It basically operates between 88%-91% across the entire range of load outputs and, to quality as bronze, the minimum is 81% by EU standards.

PFC (Power Factor Correction)

While a little on the low side at 20% load, when pushed harder the PFC rating for the Xilence Performance A+ III Series is, similar to the efficiency rating, excellent and much higher than you might have expected.

Between 60%-100% this averages around 0.97 which is honestly as good as you could’ve wished and a clear indication that this power supply has (despite some concerns) been built to a very high standard.

Voltage Regulation

While there is a little movement in the figures (based on the overall output) the main key factor is consistency and as you can see from the deviance, the results are nice and tight! As such, no matter how much power you’re asking from the Xilence Performance A+ III Series, it’ll have no problem obliging you at a nice smooth level!
