This article covers LIAN LI SP 850 80+ ゴールド ホワイト パフォーマンス SFX フォームファクタ電源.

Overview

LIAN LI's SP850 WHITE is an SFX-form-factor power supply unit delivering 850W with 80 PLUS Gold certification. Its white casing makes it a natural match for white-themed PC builds, offering both performance and aesthetic harmony. The fully modular cable design lets you connect only the cables you need, greatly simplifying cable management in tight spaces. Despite its compact SFX size, this PSU packs enough power to support mid-range to high-end gaming rigs. The 80 PLUS Gold efficiency rating ensures lower heat output and better energy savings compared to standard units. A 12VHPWR cable is included, but it lacks sideband contacts, meaning it does not support NVIDIA GeForce RTX 40-series graphics cards—an important caveat for current-gen builders. With a noise level ranging from 17.1 to 40.6 dBA and a semi-passive fan mode that keeps the fan off under light loads, the SP850 WHITE is designed for quiet operation. It also features an inrush current limiter for additional protection, making it a reliable choice for compact high-performance systems.

Compatibility Guide

The SP850 WHITE is built for SFX-compatible cases, including most small-form-factor (SFF) enclosures. If you plan to install it in an ATX case, you will need an SFX-to-ATX adapter bracket (sold separately). The unit's dimensions follow the SFX standard (typically 125 x 100 x 63.5 mm), so measurement clearance is rarely an issue. Connector inventory: 1x 24/20-pin motherboard connector (300mm) 2x 8/4+4-pin CPU/ATX12V connectors (600mm) 2x 8/6+2-pin PCIe connectors (400mm) 1x 12VHPWR cable (400mm, no sideband contacts) * SATA and 4-pin peripheral connectors The CPU cable length of 600mm provides ample routing space even in SFX cases. Note that the 12VHPWR cable is non-functional with RTX 40-series cards; use the included PCIe 8-pin cables with an adapter in that case.

Product Info

Released in late 2022, the LIAN LI SP850 WHITE sits in the upper-mid tier of the SFX PSU market. It is available on Japan for around ¥35,000 and comes with a 5-year warranty. Key performance specs: Rated output: 850W (840W on +12V rail, 70A) 80 PLUS Gold certified (up to 92.6% efficiency at 20% load) Input voltage: 100–264V AC with active PFC Fan noise: 17.1–40.6 dBA Zero RPM fan mode, kick-in threshold adjusted to 60°C (up from 45°C on the SP750) Inrush current limiter for protection The unit's efficiency curve peaks at around 50–60% load, making it an excellent fit for systems that draw between 400W and 600W under typical gaming loads.

Best Use Cases

White-themed PC builds The SP850 WHITE's white chassis and white cables (included) are perfect for builders aiming for a clean, all-white aesthetic. Pair it with a white case and motherboard for a visually cohesive system. Small-form-factor gaming PCs With 850W capacity in an SFX package, this PSU is ideal for mini-ITX or micro-ATX builds housing high-end CPUs (e.g., Ryzen 7, Core i7) and mid-to-high-end GPUs like the RTX 3070 or RX 6800. The fully modular design helps keep airflow unobstructed in cramped interiors. Users prioritizing quiet operation The semi-passive fan mode ensures near-silent operation during light tasks, while the fan noise stays under 40 dBA even under full load. This makes the SP850 WHITE suitable for home theater PCs or workstations where noise is a concern. ## Alternatives
Direct competitors include the Corsair SF750 Platinum (SFX, 750W, 80 PLUS Platinum, higher efficiency but lower wattage) and the Cooler Master V850 SFX Gold (SFX, 850W, 80 PLUS Gold, ATX 3.0 support on some variants). Corsair's SF750 offers Platinum efficiency and exceptional fan noise profile, but at 750W it may be insufficient for high-end upgrades. Cooler Master's V850 SFX Gold matches the SP850 in wattage and efficiency, and some revisions include ATX 3.0 compliance with a 12VHPWR cable that supports RTX 40-series. However, the Cooler Master unit is rarely available in white, giving the LIAN LI an edge for themed builds.

Things to Consider

The most significant limitation is the 12VHPWR cable's incompatibility with RTX 40-series graphics cards. If you own or plan to buy a GeForce RTX 4070 or higher, you'll need to use the included PCIe 8-pin cables with the GPU's provided adapter, which can add clutter. Secondly, this is an SFX PSU; it will not fit in standard ATX cases without an adapter bracket. Make sure your case supports SFX or purchase a bracket separately. Third, while 850W is sufficient for most mid-to-high-end builds, it may be borderline for systems drawing over 800W under sustained load—especially with future high-power GPUs. For extreme setups (e.g., RTX 4090 + Ryzen 9), consider a higher-wattage SFX unit like the SilverStone SX-1000. Finally, the 5-year warranty is standard for this class, but some competitors offer 7 or 10 years. If long-term peace of mind is a priority, compare warranty terms before purchasing.
