• Fully compatible with ATX 3.1 and PCIe 5.1 standards.
• Full modularity for the best cable management options.
• Added 12V-2×6 cable to comply with the new graphic cards.

Note: Seasonic VERTEX Series PSUs were initially shipped with 12VHPWR cables. Following the ATX standard update, we transitioned to 12V-2×6 connectors. During this period, customers may receive either cable, depending on the region. The updated VERTEX version is expected later in 2025 for Europe and North America. We apologize for any inconvenience.
