it has been working for 2 years and there are no problems, I set it and forgot, I didn’t even remember. despite the fact that I have constant power surges in the network such that when I put the cut-off switch on the meter, I had to push the current frame 3 times, because otherwise there is no light in the house every 10 minutes (((current from 160 -280 jumps on the TV only and I hear light clicks of the stabilizer ( separate) that goes into a particularly low current mode and back, but nothing burned on the computer for 2 years and didn’t even notice it, so it’s quite a tolerable power supply he would have more outputs to video cards, because modern ones already need 3 pci outputs, and here 2 and the most powerful ones will no longer work, although 750 watts should have been enough, and installing power splitters is worse for doing it because they can just burn the video card.

Tempting price and high quality
Xilence made a name for itself as a maker of good, affordable power supplies, but a few years ago the company tried to pivot and take a shot at the high-end market. The attempt to shed its old image didn’t pan out, and Xilence was acquired by Listan (which also owns the be quiet! brand), who decided to steer things back onto the budget track. One of the first models of the refreshed brand was the Performance X power supply lineup, which stands out first and foremost for its tempting price-to-quality ratio.
Gold for cheap
In testing, the Xilence Performance X proved to be a pretty reliable little unit. Compared to the previous Xilence Performance A+ series, the newcomer is built on a more advanced platform featuring LLC resonant conversion with DC-DC converters for the secondary rails. As a result, you get 80+ Gold efficiency, stable output voltages even under notable load, and low ripple and noise. And with 550 W on tap, you can build a thoroughly modern gaming or work system around it with a 6-core CPU and a capable graphics card like an RTX 2060 SUPER.
Quiet at the workplace
Cooling is handled by fans with hydrodynamic bearings, and their speed is automatically adjusted based on temperature. Noise under load doesn’t exceed 23 dB. Otherwise there are no standout technical features or visual flourishes: you get two PCIe, six SATA, and three Molex connectors — a perfectly adequate set for its class. The manufacturer’s warranty is two years, and you can extend it by another year after registering your unit on the official website.
