be quiet! Pure Power 12 M 750 W, model BN504. 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 | be quiet! Pure Power 12 M 750 W, model BN504 |
|---|---|
| Form factor / era | ATX 3.0 / PCIe 5.0 ATX, 750 W |
| AC input | 100–240 V AC, 50/60 Hz (model label controls). |
| DC output rating | 750 W continuous; +12 V combined up to 62.5 A; minor-rail limits and cross-load limits are manual-specific. |
| Mechanical envelope | 160 × 150 × 86 mm, ATX. |
| Connectors / interface | Modular 24-pin ATX, EPS/CPU, PCIe, SATA and peripheral; the BN504 bundle has a 12VHPWR-era GPU lead—verify its manual and compatible GPU instructions. |
| Revision differences | BN504 identifies the 750 W generation; successor Pure Power 12 M ATX 3.1 variants and later cables may differ. Do not collapse wattage/SKU variants into one record. |
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
Keep BN504 model number and cable set together. Record any later retail revision, connector designation (12VHPWR versus 12V-2x6), and manual issue date.
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.
