Lian Li – SP 850 V2 Gold 850W SFX 80+ Gold Fully Modular ATX 3.1 PSU Black / White – SP 850G

Compact Size, Big Performance

Engineered for enthusiasts who demand zero compromises in their small-form-factor PCs, the Lian Li SP V2 Gold perfectly bridges the gap between massive power delivery and compact design. Measuring an incredibly space-efficient 125 × 100 × 63.5 mm, this SFX power supply effortlessly fits into ITX and tightly spaced builds. Despite its small footprint, it houses premium Japanese electrolytic capacitors wrapped in a sleek aluminum housing, offering unparalleled durability and long-term electrical stability for the most power-hungry components.

Next-Gen ATX 3.1 & PCIe 5.0 Ready

Stay ahead of the curve with native ATX 3.1 compliance and dedicated PCIe 5.0 graphics card support. The SP V2 Gold features a custom-engineered 12V-2×6 power connector, built in-house with alloy copper soldered terminals for superior conductivity. Designed specifically to eliminate mounting interference, this connector sports an optimized 20.5mm width and a dual-color housing layout. Simply ensure the blue section is fully inserted, and you have a secure, ultra-safe power line capable of safely handling extreme transient spikes from cutting-edge GPUs.

80 PLUS Gold Efficiency with Silent Operation

Operating at maximum performance doesn’t mean sacrificing efficiency or peace and quiet. With an 80 PLUS Gold certification, this power supply guarantees over 90% efficiency at a 50% system load (115V). This lowers ambient temperatures inside your chassis and visibly reduces energy costs. Cooling is actively managed by a highly reliable 92mm Fluid Dynamic Bearing (FDB) fan that features a ZERO RPM mode. Under light or idle loads, the fan stops spinning entirely, treating you to a perfectly silent computing experience. When heavy loads hit, it expertly scales up to 3000 RPM while maintaining quiet acoustics.

Fully Modular Design and Elite Protection

Cable management in ITX cases is notoriously difficult, which is why the SP V2 Gold utilizes a fully modular architecture combined with premium, anti-tangle embossed cables. This textured cable design drastically improves flexibility while reducing annoying knots, enabling a pristine and airflow-optimized build. Moreover, Lian Li backs this unit with a commanding 10-year warranty and a full suite of industrial-grade safeguards—including Over Current (OCP), Over Voltage (OVP), Short Circuit (SCP), Over Power (OPP), Under Voltage (UVP), and Over Temperature (OTP) protection—ensuring your PC remains safe under any circumstance.
