Lian Li SX0850P Black (G9P.SX0850P.B000.EU)

The Lian Li SX0850P Black (G9P.SX0850P.B000.EU) is an 850 W ATX power supply designed for high-performance gaming systems, emphasizing compact case depth, modern power delivery standards, and fully modular cable management. According to Cybenetics testing data, the Lian Li SX0850P Black measures 150×85×140 mm and features a 120 mm fan with FDB bearing technology supporting selectable semi-passive operation, allowing the fan to enter a low-noise cooling mode depending on load and usage profile. The +12 V rail delivers up to 70.8 A or 849.6 W, while +3.3 V and +5 V combined provide 100 W, which is typical for modern ATX designs prioritizing CPU and GPU power delivery. The unit meets the ATX 3.1 standard, includes a native 12+4-pin PCIe cable rated for 600 W, and provides four additional 6+2-pin PCIe connectors, two 4+4-pin EPS connectors for the processor, eight SATA, and four Molex connectors. Cybenetics testing showed average efficiency of 90.67% at 115 V and 92.36% at 230 V, with noise levels around 22 dBA, making this model a balanced choice for energy efficiency and acoustics. For compact ATX builds requiring a next-generation high-power graphics card, the Lian Li SX0850P Black offers a practical solution without needing to move up to longer 160–180 mm models.
