ASUS ROG Strix 1200W Platinum Power Supply – GaN MOSFET, GPU-First Voltage Stabilizer, 80+ & Cybenetics Platinum, ATX 3.1, PCIe 5.1 12V-2×6, 0dB, Lambda A – Black | 90YE00W0-B0NA00

GaN MOSFET — Superior Efficiency

GaN MOSFET delivers superior power efficiency by up to 30% and a more organized internal layout for cooler operation — keeping the ROG Strix 1200W Platinum running cool and efficient even under heavy gaming loads.

GPU-First Voltage Sensing

GPU-First voltage sensing with a patented intelligent voltage stabilizer enhances voltage delivery by up to 45% to your graphics card — for smoother gameplay and unwavering performance where it matters most.

Cool and Quiet

Large ROG heatsinks cover critical components, delivering lower temperatures and noise than reference designs. Dual ball fan bearings can last up to twice as long as sleeve bearing designs, and 0dB technology lets you enjoy light gaming in relative silence — the fan only spins up when the system reaches a certain load. Lambda A certification guarantees low noise levels below 25 dB.

Ready for Next-Gen

ROG Strix Platinum is compliant with the ATX 3.1 standard, ensuring enhanced voltage and current regulation, and features a native 12V-2×6 connector for next-generation graphics card power. 80 PLUS and Cybenetics Platinum certifications leverage low-ESR capacitors and premium components for industry-leading power efficiency, with a rated MTBF of over 120,000 hours at 25°C and complete protection: OPP, OVP, UVP, SCP, OCP and OTP.
