| DC output rating | 850 W continuous; combined +12 V rated 70.8 A class; read the DC output table for rail maxima and current sharing. |
| Mechanical envelope | 160 × 150 × 86 mm, ATX (confirm with CP-9020270 manual). |
| Connectors / interface | Fully modular 24-pin ATX/EPS/PCIe/SATA; newer revision includes 12V-2x6 GPU cable. Exact supplied connectors are SKU dependent. |

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.
