Power supply unit Lian Li SP V2 Gold 850 W SFX 20+4 pin ATX 80 PLUS Gold Black

The Lian Li SP V2 Gold is a compact SFX power supply delivering up to 850 W of stable power while fitting small-form-factor builds. It supports modern high-power components with an ATX 3.1–compatible 12V-2×6 connector and offers 80 PLUS Gold efficiency for reduced energy loss. The unit measures 125 × 100 × 63.5 mm, includes a single 92 mm fluid dynamic bearing (FDB) fan with zero-RPM capability, and uses premium Japanese electrolytic capacitors for long-term reliability.

Advantages

The SP V2 Gold combines compact dimensions with high efficiency and next-generation GPU support. Fully modular braided cables and an embossed anti-tangle design improve cable management and durability. Its custom 12V-2×6 power cable with alloy copper soldered terminals and dual-color connectors ensures stable, secure connections and prevents clearance issues during GPU installation. Built-in protections (OCP, OVP, SCP, OPP, UVP, OTP) and an inrush current limiter help maintain safe, stable operation.

Suitable for

• Compact gaming PCs and small-form-factor builds
• Systems using modern PCIe 5.0 graphics cards
• Quiet home or office workstations requiring efficient power delivery
• High-performance compact builds with limited internal space

How to use

Install the SP V2 Gold into an SFX-compatible PSU bay following standard PSU mounting procedures and connect the 20+4 pin ATX cable to the motherboard. Use the included modular cables to connect the GPU via the native 12V-2×6 connector and attach storage and peripheral power cables as required. Ensure correct AC input voltage and secure cable routing to avoid obstruction of airflow. The fan operates silently at low loads and will increase speed automatically under higher thermal conditions.

Recommendations

For best results, pair the SP V2 Gold with a case and GPU that accommodate the SFX form factor and the 12V-2×6 connector width. Keep ventilation clear around the PSU and periodically check cable connections and dust buildup to maintain efficiency and longevity.
