PROLAB DESIGN XPower XP-850 Gold Fully Modular ATX 3.1 Power Supply ( 850W )

The PROLAB DESIGN XPower XP-850 is an 850-watt, fully modular power supply built to the ATX 3.1 standard and compatible with PCI Express 5.1 graphics cards. Its 80 PLUS Gold certification means it meets verified efficiency thresholds at typical load levels, reducing waste heat inside the chassis compared with lower-rated units. Cable management is straightforward thanks to the fully modular design: every cable — including the 24-pin motherboard connector and PCIe leads — detaches completely, so you keep only what your build actually needs. Three PCIe 6+2-pin connectors serve multi-GPU or high-TDP single-GPU configurations, while eight SATA connectors and two 4-pin peripheral connectors cover storage-heavy or accessory-rich systems. The XP-850 uses a 120 mm PWM fan mounted on a fluid dynamic bearing. Fluid dynamic bearings are known for smooth, low-friction operation, which helps keep acoustics in check during sustained workloads. Active Power Factor Correction (Active PFC) conditions the incoming AC supply for more stable delivery, and the 105 °C-rated Japanese capacitors are chosen for longevity under continuous high-load conditions. Whether you are assembling a high-refresh-rate gaming PC, a content-creation workstation, or a future-proofed desktop that needs headroom for upcoming PCIe 5.1 graphics hardware, the XP-850 is dimensioned and connectorised accordingly.
