Platinum Performance
80PLUS Platinum EfficiencyThe 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.
High-Quality Capacitors
Constructed With CarePremium Japanese electrolytic capacitors are known for their reliability and durability. They regulate voltage and filter out noise, ensuring stable power delivery. These capacitors are highly regarded for their quality, longevity, and heat resistance, making them ideal for PSUs to maintain performance and reduce the risk of instability or failure over time.
Excellent Compatibility
Constructed With CareThe 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.
