This is a dedicated replacement 24Pin ATX mainboard modular power cable tailor-made for Seasonic legacy full modular power supplies, perfectly matching X-1250, X-1050, X-850, X-750, X-650 and KM3 series models with exclusive 18+10 pin modular sockets on the PSU side.

One end adopts the special 18+10 combined connector that precisely plugs into the power supplys proprietary motherboard modular port, while the other end outputs standard split 20+4 pin 24Pin ATX connector, compatible with all ATX, MATX, ITX motherboards in the market to complete the mainboard primary power supply connection.

The whole wire is wrapped with dense nylon braided sleeving, which effectively resists abrasion, bending fatigue and electromagnetic interference inside the crowded PC chassis, also greatly optimizing airflow and heat dissipation by tidying up internal wiring. Built with high-gauge tinned oxygen-free copper wire core, it offers ultra-low resistance to sustain continuous heavy load power output, avoiding system crash, blue screen or automatic shutdown during GPU overclocking, rendering and gaming high-load scenarios.

Each terminal is equipped with sturdy lock buckles to firmly lock the plugs into PSU and motherboard ports, eliminating hidden dangers of poor contact. Important safety reminder: This cable only fits the listed Seasonic X/KM3 series power supplies, do not use it on other brand or different Seasonic series PSUs to avoid hardware burnout. It is an essential upgrade accessory for DIY PC builders, workstation assembly and old Seasonic power supply reuse renovation.
