Xilence Performance X XP550R9 (XN071)

Attractive price and high quality

Xilence has a reputation for making good, affordable power supplies, but a few years ago they decided to branch out and try their luck in the high-end market. An attempt to get rid of the old image was unsuccessful, Xilence was bought out by Listan (which also owns the Be Quiet brand), which decided to put the process back on a “low-cost” track. One of the first models of the old-new brand was the Performance X power supply line, which attracts primarily with its attractive price-quality ratio.

Gold on the cheap

In tests, the Xilence Performance X proved to be a pretty reliable small. Compared to the previous Xilence Performance A+ line, the new product is based on a technically more advanced platform based on LLC resonant conversion technology with DC-DC converters for secondary voltages. As a result, we got a high level of efficiency of 80+ Gold, stable output voltages even under a noticeable load, and low levels of ripple and noise. Well, the available power of 550 W allows you to build on the basis of this block a fairly modern gaming or work system with a 6-core processor and a high-performance graphics card of the RTX 2060 SUPER level.

Silence in the workplace

To cool the components, the power supplies are equipped with fans with hydrodynamic bearings, the rotation speed of which is automatically adjusted depending on the temperature. The noise level under load does not exceed 23 dB. Otherwise, there are no outstanding technical details or visual accents here: there are two PCI-E outputs, six SATA and three Molex, that is, quite a sufficient set for its class. The manufacturer's warranty is limited to two years, but it can be extended for another year after registering your model on the official website.
