how to install XPG COREREACTORII850G-BKCUS 850W Power Supply

• Power down your system, unplug the power cord, and discharge any residual power by pressing the power button a few times.
• Open your PC case and remove the existing PSU if you are upgrading. Place the XPG CORE REACTOR II into the PSU mounting area, aligning the screws with the case’s rear panel.
• Secure the PSU with screws through the case’s mounting holes to ensure a stable installation with no movement.
• Connect the 24-pin ATX main power cable to the motherboard and the 8-pin (or 4+4) CPU power connector to the motherboard’s CPU power socket. If your motherboard requires additional power, attach the appropriate auxiliary connectors from the modular cable set.
• Attach PCIe power cables to your graphics card(s). Use 6+2 pin connectors as required by your GPU(s). Connect SATA and Molex power cables to storage drives, fans, or other components as needed.
• Organize and route cables to maximize airflow and reduce clutter inside the chassis. Secure cables with zip ties or Velcro straps, avoiding any obstruction of intake or exhaust fans.
• Plug the system back in and power on to test. If the system does not start, double-check all power connections and ensure the switch on the PSU (if present) is in the ON position. Monitor for proper POST beep codes or motherboard status LEDs to verify correct installation.
• Run a quick stability test under load to confirm that voltages remain within safe tolerances and that the PSU is delivering stable power to CPU, GPU, and other components.
