Thermaltake Toughpower GF3 850W Gold (2025 Version)
The 2025-revision 850 W Toughpower GF3 Gold, SKU PS-TPD-0850FNFAGU-4. Do not assume its connector or ATX revision details apply to earlier GF3 850 W 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 | Thermaltake Toughpower GF3 850W Gold (2025 Version); model / SKU PS-TPD-0850FNFAGU-4. 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 A maximum, 47–63 Hz. |
| DC rails | +12 V: 70.5 A (846 W); +3.3 V: 20 A; +5 V: 20 A; +3.3 V/+5 V combined: 110 W; −12 V: 0.3 A; +5 VSB: 2.5 A. |
| Connector set | 24-pin ATX; two 4+4-pin EPS; four PCIe 6+2-pin; one native 12V-2x6 (16-pin); six SATA; four peripheral 4-pin. |
| ATX / PCIe revision | ATX 3.1 / PCIe 5.1, 2025 revision. Distinct product SKU from the earlier GF3 850 W family generation. |
| 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
- This SKU’s cable set and revision are not interchangeable by family name alone. Follow Thermaltake’s native 12V-2x6 instructions and confirm GPU clearance, the full rail table, and exact chassis 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.
