PLATINUM CERTIFICATE

Experience next-level performance with the SX Platinum series, which is 80 PLUS@ Platinum and PPLP Platinum certified and fully compliant with AT X 3.1 and PCIe 5.1 standards. It provides stable +12V power, silent fanless cooling up to 40% load, and excellent durability with high-quality Japanese capacitors backed by a 10-year warranty.

PLATINUM PERFORMANCE
Certified with 80 PLUS@ Platinum and PPLP Platinum, the SX Platinum series delivers up to 92% efficiency at 50% load for cooler operation, quieter acoustics, and lower energy costs. Designed for professional reliability, it ensures excellent performance with tight voltage regulation and ultra-low ripple, keeping your GPU and CPU stable even during sharp power fluctuations.

SMART STOP/START FOR SILENT OPERATION

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

FULLY MODULAR
The fully architectural design gives you the freedom to install only the cables your setup requires, keeping your system tidy, optimized, and ready to show off.

BRAIDED CABLES FOR PERFECT RESULTS
The SX Platinum series includes braided cables and cable combs to improve 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 fluctuations of up to 200% of its rated output, it provides stable power for high-performance systems, ensuring smooth and reliable gaming.

STABLE DUAL-COLOR PCIE 5.1 CONNECTOR
Equipped with a 12V-2×6 copper alloy terminal for safe and efficient power delivery, enhancing system stability and performance.

ENOUGH PCIE 6+2 POWER SUPPLY SUPPORT
It includes three PCIe 6+2 cables, as well as two additional 12V-2×6 cables to dual PCIe 6+2 Pin cables on the 1000W and 1200W models, providing reliable support for multiple devices.

TRIPLE GPU SUPPORT PCIE 6+2 PIN
It provides up to five PCIe 6+2 slots (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 CAPACITORS 105C

All electrolytic and solid capacitors are from leading Japanese brands such as Rubycon, Nippon Chemi-Con or Nichicon and are 105C rated components. These high quality capacitors ensure stable voltage regulation, lower ripple and long term reliability, even in high temperature operating conditions.

STANDARD SIZE FOR BETTER COMPATIBILITY WITH CASES

The SX Platinum series uses a highly compatible standard ATX form factor with a length of just 140 mm, which fits a wide range of cases and leaves more internal space during installation.

COMPLETE PROTECTION

Equipped with OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP protection to protect against over-current, over-voltage, overheating, overload and short circuit conditions for reliable operation.

TEN-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.
