Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.
The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are greater than that of the FSP AURUM Xilenser 500W, we can test it to the maximum.
The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.
Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rails, we see 1% regulation from start to finish on both rails. 12V1 showed a total drop of .07V from start to finish and 12V2 showed a total drop of .07V from start to finish. The 5V rail managed to stay within 3% of specification with a total drop of .12V from start to finish. Moving towards the 3.3V rail, we see that regulation was still within 3% with a total voltage drop of .09V.
DC Output quality for the FSP AURUM Xilenser 500W was a bit lower than we had expected, but still well within specification. During Test 1, we saw 29mV of noise on our scope. When we increased the loads in Test 2, the ripple climbed to 35mV. Under full load, the Xilenser 500W showed us a maximum of 40mV of noise.
The FSP AURUM Xilenser 500W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87%/90%/87% efficiency at 20%/50%/100% loads respectively. As you can see, the Xilenser 500W passed on our bench.
While FSP might be new to branding their own units, they are doing a very good job of getting noticed and making sure they stick around. The Aurum Xilenser line of power supplies represents another option for the silent computing crowd and there just aren't that many fanless units available. This is only the second fanless unit we've been able to get our hands on over the last few years and we must say it is something that is much needed.
The Xilenser 500W on our bench today does an excellent job of mixing the good with the bad. The build quality of our unit is great and features Japanese made capacitors throughout the entire power supply. Higher grade capacitors are even more important in fanless units as they are likely to see higher temperatures and stressed more than an actively cooled unit. Even if things were to get too hot, the OTP of the unit should protect you from having a catastrophic meltdown and the Xilenser 500W from dying.
Performance for the Xilenser 500W is mostly just what you would hope for. Voltages are stable with tight regulation across the board. The unit is very efficient too, almost enough to warrant a Platinum rating instead of Gold. Noise suppression was the weakest area of performance and even then it wasn't bad and well within spec. One would hope for this to be a bit better considering the price of $180. There might be other units on the market with better noise suppression, but they are all actively cooled as well.
All of this comes together in a unit that should give you silent power without issues so long as you keep in mind that fanless power supplies aren't design for high heat environments. You might have to pay a little bit more to go silent, but that is quite typical for fanless power supplies as well. At least FSP fives you the option to save a few bucks and go without modular cables or spend a few more and opt for less cable clutter.
