Intel ATX12V 1.3 power-supply profile
Intel ATX12V design-guide revision 1.3 reference family. This record is bounded to the named unit, standard revision, or model family below; nearby model names and replacement parts are not presumed equivalent.
HIGH-VOLTAGE SAFETY: Unplug before external inspection. Never open a power supply. Dangerous voltage can remain inside after it is disconnected. Do not attempt internal repair; use qualified service or replace the unit.
Verified identity & specifications
| Catalog identity | Intel ATX12V design-guide revision 1.3 reference family |
|---|---|
| Form factor / era | ATX12V transition / 20-pin ATX plus 4-pin CPU |
| AC input | The guide defines electrical requirements, not a product-specific AC input; read the actual supply nameplate. |
| DC output rating | Adds a dedicated +12 V CPU power path and defines regulated +12 V, +5 V, +3.3 V, −12 V, and +5 VSB behavior; rail current remains model-specific. |
| Mechanical envelope | Standard ATX outline; the specification revision does not dictate a single PSU length or cooling layout. |
| Connectors / interface | 20-pin main ATX connector plus 4-pin ATX12V CPU connector in the usual generation; consult the design guide for pinout and signal details. |
| Revision differences | Revision 1.3 reflects changed minimum loading/efficiency and legacy −5 V treatment versus earlier ATX-family designs; implementation date and actual connector population vary by product. |
Compatibility & safe handling
- Match full model, suffix, region, revision and DC output label to the official documentation. Rated total watts alone do not establish rail or transient compatibility.
- Before replacement, confirm AC input range, rail current/combined limits, motherboard signaling and pinout, mechanical envelope, fasteners, cooling direction, and every required connector.
- Never open the PSU, defeat protective earth, or probe its internals. Do not energize a wet, cracked, corroded, burned, modified, or unidentified supply.
- Modular cable pinouts are not standardized at the PSU end. Use only cables expressly approved for this exact model/revision; matching plugs can have different wiring.

Archival notes
Catalogued as a bounded standards family, not a product SKU. Record the standard revision printed in a product manual; never infer motherboard compatibility from the ATX label alone.
Photograph the complete nameplate, assembly/model code, revision/date code, input selector if present, cable ends and mounting side. Separate observed label data from published specifications and preserve the referenced manual issue.
