Platinum Certified

Experience next-level performance with the SX Platinum Series, featuring 80 PLUS® Platinum, PPLP Platinum certifications and full compliance with ATX 3.1 and PCle 5.1 standards. It delivers stable +12V power, whisper-quiet fanless cooling up to 40% load, and exceptional durability with premium Japanese capacitors backed by a 10-year warranty.

80 PLUS Platinum Efficiency

The SX Platinum Series delivers up to 94% conversion efficiency at 50% load, achieving 80 PLUS® Platinum-level performance and reducing AC losses and heat, allowing your system to run cooler, quieter, and more cost-effective over time.

Smart Stop/Start for Quiet Operation

When the PSU load is at or below 40%, the fan enters its smart stop/start mode to keep the system quiet under low loads. This feature can also be enabled or disabled using the switch on the rear of the unit.

Fully Modular

A fully modular design gives you the freedom to install only the cables your setup calls for, keeping your system neat, optimized, and ready to showcase.

Braided Cables for A Finished Look

The SX Platinum Series includes braided cables and cable combs to enhance both appearance and durability, making cable management easier and giving your build a clean, professional finish.

ATX 3.1 And PCIE 5.1 Standards

Supporting power excursions up to 200% of its rated output, it delivers able power for high-performance systems, ensuring smooth and reliable gameplay.

Stable Dual-Colour PCIE 5.1 Connector

Equipped with a 12V-2x6 copper-alloy terminal for safe and efficient power delivery, enhancing system stability and performance.

Ample PCIE 6+2 Power Support

Includes three PCle 6+2 cables, plus two additional 12V-2x6 to dual PCle 6+2 Pin cables on the 1000W and 1200W models, providing reliable support for multiple devices.

Triple PCIE 6+2 Pin GPU Support

Provides up to five PCle 6+2 connectors (four on the 850W model), meeting the power needs of high-end AMD graphics cards. This flexible design makes it an ideal choice for users planning future performance upgrades.

100% Japanese Rubycon 105°C Capacitors

All electrolytic and solid capacitors are sourced from leading Japanese brands, Rubycon, Nippon Chemi-Con, or Nichicon, and are 105°C-rated components. These high-grade capacitors ensure stable voltage regulation, lower ripple, and long-term reliability even under high-temperature operation.

Standard Size for Better Case Compatibility

The SX Platinum Series uses a highly compatible standard ATX form factor with a length of only 140 mm, fitting a wide range of cases and leaving more interior space during installation. Ideal for users looking to install an ATX PSU in an mATX case, the 140 mm standard length offers better compatibility, frees up cable-routing space, and enhances the overall building experience.

Vented Front Panel for Better Airflow

The patterned open-mesh front panel boosts both the PSU's appearance and cooling performance.

Comprehensive Protection

Equipped with OCP, OVP, OTP, OPP, SCP, UVP, NLP, and SIP protection to guard against overcurrent, overvoltage, overheating, overload, and short- circuit conditions for reliable operation.

10-Year Warranty

Built with high-quality components for long-term stability, the SX Platinum Series comes with a 10-year warranty for added peace of mind.
