How to Install XPG CORE REACTOR COREREACTOR850G-BKCUS 850W Power Supply

• Power down your computer and unplug it from the wall. Discharge any remaining static by briefly touching a grounded metal surface.
• Remove the side panel of your PC case to access the interior. If you’re upgrading, carefully document or disconnect existing cables to avoid confusion during reassembly.
• Mount the COREREACTOR850G-BKCUS securely in the case’s power supply area using the screws provided with your case. Ensure the unit is oriented to allow for optimal airflow and cable routing behind the motherboard tray.
• Connect the motherboard power cable (24-pin) and the CPU power connector (typically 8-pin or 4+4-pin) from the modular cables to the appropriate motherboard headers. Route these cables neatly and consider tucking them behind the motherboard tray for clean aesthetics and airflow.
• Attach PCIe power cables to your graphics card(s) and connect SATA or peripheral cables as needed for storage drives and other components. Use only the cables that you need to minimize clutter and maximize airflow.
• Inspect all connections to ensure they’re firmly seated. Close the case, restore power, and power on the system. If your motherboard or BIOS shows normal readings and the system boots, you’ve completed a successful installation.
• Optionally, test the supply with a PSU tester or your motherboard’s POST screen to verify voltages are within expected ranges under idle and load conditions. If you notice abnormal voltages or instability, recheck connections and consider reseating cables or addressing any hardware issues.
• Maintain good airflow by organizing cables with zip ties and ensuring intake and exhaust fans have clear paths. Periodically inspect the cables during future upgrades to prevent wear and maintain performance.

Frequently asked questions

• Q: Is 850W enough for my build? A: For most mid-to-high-end gaming rigs and productivity systems, 850W provides ample headroom. It’s particularly suitable for builds with a high-end GPU, overclocked CPUs, multiple drives, and additional PCIe devices. If you plan a multi-GPU configuration or extremely power-hungry components, verify total peak draw and consider future upgrades when assessing your power needs.
• Q: Is this power supply fully modular? A: Yes. The COREREACTOR850G-BKCUS uses a fully modular cabling system, allowing you to connect only the cables you need. This simplifies cable management, improves airflow, and makes upgrades or changes easier without clutter.
• Q: What does LLC topology mean for my system? A: LLC (Line Level Control) resonant topology improves voltage stability and reduces ripple on the major rails. This contributes to cleaner power delivery, steadier overclocking potential, and enhanced protection for sensitive components such as CPUs and GPUs, especially under dynamic workloads.
• Q: Are Japanese capacitors better? A: Japanese capacitors are widely regarded for their quality, reliability, and performance consistency. Using 100% Japanese capacitors in this PSU helps ensure longer life, steadier operation, and better ripple management compared with some lower-cost alternatives.
• Q: Will this PSU fit in my case? A: The COREREACTOR850G-BKCUS is a standard ATX power supply designed to fit most mid-tower and full-tower cases. Always check your case’s PSU mounting dimensions, clearance for cables, and height limitations to ensure compatibility with any sleeves, radiators, or fan configurations you plan to use.
• Q: What protection features are included? A: The unit includes a broad set of safeguards—over-voltage, under-voltage, over-current, short-circuit, and thermal protections—designed to protect both the PSU and connected components during power fluctuations or faults.
