SilverStone DA850R Gold
SilverStone DA850R Gold, manufacturer model SST-DA850R-GM. The R-series Gold variant is not the same SKU as the SX750/SX850 compact SilverStone units. 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 | SilverStone DA850R Gold; model / SKU SST-DA850R-GM. 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 | 90–264 V AC, 47–63 Hz; maximum current and regional ratings are on the unit label. |
| 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 | 24/20-pin ATX; two 4+4-pin EPS/ATX12V; four PCIe 6+2-pin; one 12VHPWR 12+4-pin; eight SATA; six 4-pin peripheral; two FDD. |
| ATX / PCIe revision | ATX 3.0 / PCIe 5.0 model generation with 12VHPWR; not 12V-2x6/ATX 3.1 by implication. |
| Mechanical envelope | 140 × 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, OPP, OVP, SCP and OTP; review the model manual and label for complete behavior. 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 model’s PCIe 5 connector is the 12VHPWR-generation interface. Use its included lead only as documented; do not identify it as 12V-2x6 just because it is a 16-pin connector. Confirm PSU depth and GPU insertion/bend clearance.
- 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.

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.
