Power supply Lian Li SP0850G.W 850 W SFX 80 PLUS Gold 20+4 pin ATX White

Lian Li SP0850G.W is a compact SFX power supply delivering 850 W total power with 80 PLUS Gold efficiency. Designed for small-form-factor systems, it measures 125 × 100 × 63.5 mm and features a white aluminum housing, a 92 mm fluid dynamic bearing (FDB) fan with Zero RPM mode, and a fully modular cable design including a 20+4 pin ATX motherboard connector. The unit supports 100–240 V input at 50/60 Hz and is optimized to power high-performance components in space-constrained builds.

Advantages

The SP V2 Gold combines high efficiency, compact size and modern connector support to meet the needs of contemporary compact PCs. Its 80 PLUS Gold certification ensures over 90% efficiency at 50% load (115 V), while Japanese electrolytic capacitors and a reinforced embossed cable design increase durability and stability. A native 12V-2×6 connector compliant with ATX 3.1 allows direct support for next‑generation PCIe 5.0 graphics cards, and the included custom Lian Li 12V-2×6 cable reduces clearance issues during GPU installation.

Suitable for

• Small-form-factor gaming and workstation builds
• Compact high-efficiency desktop systems
• Systems with PCIe 5.0 graphics cards requiring ATX 3.1 connector
• Silent or low-noise PC setups

How to use

Install the power supply into an SFX-compatible case or an adapter bracket if required. Connect the 20+4 pin ATX cable to the motherboard and plug the native 12V-2×6 GPU cable directly into a compatible graphics card supporting ATX 3.1/PCIe 5.0. Attach required peripheral cables from the modular ports, route the embossed cables to minimize tangling, and secure all connections before powering the system. Ensure input voltage selection and case clearance are correct prior to first power-on.

Recommendations

Use the supplied Lian Li 12V-2×6 cable for GPUs that require ATX 3.1 support to ensure proper clearance and reliable power delivery. Keep the PSU ventilated with unobstructed airflow and perform periodic checks on cable routing and connector seating. The unit is covered by a 10-year warranty when used according to the manufacturer's guidelines.
