  • ATX 3.1 + PCIe 5.1 Ready : Fully aligned with ATX 3.1 and PCIe 5.1 standards, this PSU is built for modern next-gen systems and supports power excursions up to 200% of rated output for smoother high-performance operation.【turn119207view0†L88-L90】【turn119207view0†L240-L249】
  • Native 12V-2×6 GPU Support : Equipped with a 12V-2×6 high-current copper-alloy terminal for safer, more stable delivery to modern graphics cards—exactly the kind of connector a monster gaming build expects.【turn119207view0†L122-L127】【turn119207view0†L248-L253】
  • Triple PCIe 6+2 GPU Flexibility : The 1200W model includes three PCIe 6+2 cables, plus two additional 12V-2×6 to dual PCIe 6+2-pin cables, giving wide support for powerful or multi-connector GPU setups, especially useful for high-end AMD cards and upgrade-heavy builds.【turn119207view0†L255-L265】
  • Fully Modular Cable Design : Only connect what your build actually needs. That means cleaner cable management, better airflow, and less spaghetti shame behind the motherboard tray.【turn119207view0†L227-L229】【turn119207view0†L329-L329】
  • Braided Cables With Cable Combs : Main power cables use braided sleeving, while the 24-pin, CPU, and 12V-2×6 GPU cables include cable combs for a cleaner, more premium showcase finish inside glass-panel gaming builds.【turn119207view0†L233-L239】
  • Whisper-Quiet Smart Fan Mode : The PSU supports fanless operation up to 40% load with smart stop/start behavior, so your system stays calmer and quieter during lighter gaming or everyday use.【turn119207view0†L91-L91】【turn119207view0†L188-L190】

  • 100% Japanese 105°C Capacitors : Lian Li specifies premium Rubycon / Nippon Chemi-Con / Nichicon 105°C capacitors, helping improve voltage stability, reduce ripple, and support long-term reliability under heavy thermal load.【turn119207view0†L92-L92】【turn119207view0†L266-L267】
  • Compact 140mm ATX Body : Despite its 1200W output, the SX1200P sticks to a standard 140mm depth, making it easier to install in a broad range of cases while leaving more room for cable routing.【turn119207view0†L93-L93】【turn119207view0†L271-L277】
  • Open-Mesh Vented Front Panel : The patterned vented front improves airflow while adding extra visual attitude to the PSU instead of leaving it looking like a boring power brick.【turn119207view0†L284-L286】
  • Comprehensive Hardware Protection : Built-in OPP, NLP, OVP, SCP, OCP, OTP, SIP, and UVP protections help defend the system against overload, overcurrent, overvoltage, overheating, and short-circuit conditions.【turn119207view0†L288-L290】【turn119207view0†L339-L340】
