Seasonic FOCUS SGX-650 (SSR-650SGX)
Seasonic FOCUS SGX-650 SFX-L PSU, code SSR-650SGX. This record applies only to the model and generation named here; similar wattage or connector shape does not establish equivalence.
HIGH-VOLTAGE WARNING: Disconnect mains before external inspection. Never open a PSU. Internal capacitors may retain lethal charge after unplugging. Do not probe or repair its interior; use qualified service or replace the unit.

Compatibility & safe installation
- Confirm complete model, suffix, region and revision against the unit nameplate and manufacturer manual. Do not substitute by wattage or connector-shell appearance.
- Verify AC range, per-rail and combined DC ratings, line derating, pinout, dimensions, cooling direction and qualified host support.
- Modular cables have model- and revision-specific PSU-side wiring. Use only approved leads for this exact PSU; a plug that fits may have a dangerous pinout mismatch.
- For redundant/hot-plug modules, follow the host service manual, redundancy requirements and supported replacement procedure. A server blind-mate module is not an ATX supply.
- Never open or probe a PSU. Retire damaged, wet, burnt, corroded, modified or unidentified units.
Revision & archival notes
SSR-650SGX is SFX-L, not FOCUS GX-650 SSR-650FX; same brand/model family does not assure modular cable compatibility.
Preserve SSR-650SGX code, label, manual revision and cable kit; verify fit in a case before purchase.
Archive the complete nameplate, part/spare number, manufacturing date/revision, region, connector/cable labels, mounting orientation, source document and its issue date. Separate label transcription from testing.
