Seasonic FOCUS SGX-500 (SSR-500SGX)
Manufacturer SKU SSR-500SGX. Verify the printed unit label, production revision and regional suffix against matching manufacturer documentation before selecting or installing.
HIGH-VOLTAGE SAFETY: Disconnect mains before external inspection. Never open, probe or repair a PSU; hazardous voltage can remain after unplugging. Replace damaged, wet, burned, modified or unidentified units as complete assemblies or use qualified service.

Compatibility & safe installation
- Allow SFX-L body depth and cable-bend clearance. Verify 500 W and +12 V capacity; do not infer native 16-pin GPU support.
- Check motherboard ATX main power, CPU EPS, GPU leads, peak/transient load, each rail ceiling, AC region and cooling separately; plug shape and nominal wattage alone are insufficient.
- PSU-side modular pinouts are not standardized. Never transfer, splice, repin or adapt leads unless the manufacturer approves the exact cable for this exact model and revision.
- Compare connector clearance and cable-bend space against the actual chassis. Stop if label, connector inventory or production revision differs from the listing.
- Do not open or electrically probe the PSU. Isolate mains and replace a suspect assembly; qualified technicians must follow the matching model procedure.
Revision & sourcing notes
This page distinguishes the listed SKU from adjacent capacities, regional suffixes and redesigns. Similar branding is not enough to identify a cable set or electrical table. Manufacturer documentation and the physical nameplate take precedence where revisions differ.
Published certification and ratings describe the product as specified, not the condition or remaining service life of a used PSU.
