Cooler Master MWE Gold 850 V2 Full Modular
MWE Gold 850 V2 Full Modular, identified here by MPE-8501-AFAAG-US. It is distinct from the MWE Gold 750 V2 record and from later MWE ATX 3.0 variants. Specifications below are manufacturer-source references; the physical unit’s nameplate and matching manual control.
HIGH-VOLTAGE SAFETY: Disconnect AC before external inspection. Never open, probe, or repair a PSU internally; hazardous charge can persist after unplugging. Replace a damaged, wet, burnt, modified or unidentified unit, or use qualified service.
Model-specific specifications
| Manufacturer / exact model | Cooler Master MWE Gold 850 V2 Full Modular; model / SKU MPE-8501-AFAAG-US. Match the complete regional suffix, hardware revision and label. |
|---|---|
| Rated capacity | 850 W continuous total output as the manufacturer-rated class; combined rail limits and operating-temperature derating remain model-specific. |
| Efficiency certification | 80 PLUS Gold, listed by the manufacturer for this named model. Certification does not identify an unknown PSU revision or establish used-unit condition. |
| AC input | 100–240 V AC, 12–6 A, 50–60 Hz. |
| DC rails | +12 V: 70.8 A (850 W); +3.3 V and +5 V: 22 A each, 120 W combined; −12 V: 0.3 A; +5 VSB: 3 A. |
| Connector set | 24-pin ATX; one EPS 4+4-pin; one EPS 8-pin; four PCIe 6+2-pin; 12 SATA; four peripheral 4-pin. No native 12VHPWR/12V-2x6 cable is specified for this V2 SKU. |
| ATX / PCIe revision | ATX12V 2.52 generation; not an ATX 3.x / PCIe 5.x PSU. Do not treat the separately listed MWE Gold V2 ATX 3.0 variants as the same unit. |
| Mechanical envelope | 160 × 150 × 86 mm (depth × width × height). Verify mounting holes, fan/grille clearance, cable exit/side-panel clearance and tolerance against the case drawing. |
| Protections | OCP, OVP, UVP, SCP, OPP and OTP. Protection labels do not guarantee a safe outcome under a fault; use only a healthy, unmodified unit within its documented ratings. |
Compatibility & revision caveats
- Do not infer 16-pin GPU support from an adapter or from the separate ATX 3.0 MWE Gold model. Verify native PSU-side cable compatibility, system transient requirements, modular cable pinout, and case depth.
- Confirm motherboard 24-pin and EPS count/pinout, GPU cable type, total power, rail limits, chassis dimensions, cooling clearance, region and full model suffix before purchase or installation.
- Modular PSU-side pinouts are not standardized. A cable that physically fits is not evidence of electrical compatibility; use only leads explicitly approved for this exact model/revision.
- ATX, ATX12V and PCIe connector revisions describe interfaces, not quality, safety certification or automatic compatibility with every PC component.
Manufacturer product and manual sources
- Cooler Master MWE Gold 850 V2 product pageCooler Master product page for the 850 W V2 full-modular model.
- Cooler Master MWE Gold 850 V2 family product/specification pageOfficial Cooler Master family product reference; compare against the full-modular 850 W model page and exact SKU to avoid confusion with later MWE ATX 3.0 revisions.
When a broad product-family page conflicts with a model-specific manual, label or cable table, the exact unit label and corresponding model documentation take precedence.
