Seasonic Cable Compatibility

🕒
Updated: November 2025

Seasonic PSU Cable Compatibility Guide

Modular power supply cables have revolutionized PC building, offering cleaner cable management and easier system builds. This guide helps you identify which Seasonic modular cables are compatible with your power supply. All current Seasonic series share a unified pinout design, while older or legacy platforms may use different layouts. Use the tables below to confirm which cables can safely be used with your PSU.

⚠️
Critical Safety Information

Modular cables are NOT cross-brand compatible. PSU cables from different manufacturers—and even between different series within the same brand—often use different pinouts. Using incompatible cables can result in component damage, fire hazards, or warranty voidance.

✅
Seasonic Cable Compatibility Quick Guide

Current Generation: CORE, FOCUS, VERTEX, and PRIME series share the same pinout—cables can be interchanged safely between these series. Check the detailed compatibility tables below.
Legacy Models: Older power supplies may use different pinouts. Check the detailed compatibility tables below.
Model Not Listed? Contact Seasonic Support before using cables from a different model or series.
