ATX 3.0 CERTIFIED
The ATX 3.0 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, RMe Series PSUs are formally certified for ATX 3.0 compliance.
PCIe 5.0 12VHPWR GPU cable included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.
