This article covers LIANLI SFX電源 SP850 GOLD BLACK フルモジュラー 80PLUS GOLD認証 PCIe 5.0 12ピン電源変換ケーブル付属 日本正規代理店品.

Overview

The LIAN LI SP850 GOLD BLACK is a compact SFX power supply delivering 850W of continuous power with 80 PLUS Gold efficiency. Its fully modular design allows you to connect only the cables you need, keeping your small-form-factor build tidy and improving airflow. The included PCIe 5.0 12VHPWR cable ensures compatibility with the latest high-end graphics cards from NVIDIA and AMD. Despite its small size, this PSU packs a punch. The 92mm PWM fan stays completely silent under light loads (up to 340W) thanks to a zero-RPM mode, making it ideal for quiet desktop use. Available in black or white, the unit comes with matching sleeved cables for a clean aesthetic.

Compatibility Guide

The SP850 GOLD BLACK conforms to the SFX form factor, so it fits in any case that supports SFX or SFX-L power supplies. Most Mini-ITX and many Micro-ATX cases are compatible, but if you plan to use it in a standard ATX case, you will need an SFX-to-ATX mounting bracket (not included). Connector-wise, it provides a 24-pin ATX main connector, a 4+4-pin EPS12V CPU connector, two 6+2-pin PCIe connectors, and a dedicated 12VHPWR (12+4 pin) cable for PCIe 5.0 GPUs. This means you can directly power an RTX 4070 Ti or RX 7800 XT without adapters.

Product Info

Released in late 2022, the LIAN LI SP850 GOLD BLACK sits in the upper-midrange segment of the SFX PSU market. It targets users who need high power density for compact builds without sacrificing efficiency or modern connectivity. The 80 PLUS Gold certification guarantees at least 87% efficiency at typical loads, reducing heat and electricity costs. Warranty is typically 7 years (check your region), and the unit is widely available through Japan and other major PC component retailers.

Best Use Cases

Small-form-factor gaming rigs: Perfect for Mini-ITX builds with power-hungry GPUs like the RTX 4070 Ti or RX 7900 GRE. The 850W capacity leaves headroom for overclocking and future upgrades. Silent workstation: The zero-RPM fan mode keeps the PSU inaudible during office work, web browsing, or light creative tasks. Only under heavy gaming or rendering will the fan spin up. * Cable-management enthusiasts: Fully modular design and soft sleeved cables make routing in tight spaces easy. The color-matched cables (black or white) help achieve a clean look. ## Alternatives
Direct competitors include the Corsair SF850L (SFX-L) and Cooler Master V850 SFX Gold. The Corsair SF850L is slightly longer (SFX-L), which may cause clearance issues in some ultra-compact cases. The Cooler Master V850 SFX Gold offers similar specs but often ships without a 12VHPWR cable, requiring a separate purchase. The LIAN LI SP850 stands out by including the PCIe 5.0 cable in the box and offering premium sleeved cables that match the chassis color.

Things to Consider

If you are building in a standard ATX case, remember that you will need an SFX-to-ATX bracket (not included). Also, while 850W is sufficient for most single-GPU setups, users planning to run an RTX 4090 with a heavily overclocked CPU might want to consider a 1000W+ unit for extra headroom. The zero-RPM mode is great for silence, but once the load exceeds 340W, the fan becomes audible – not loud, but noticeable. For absolute silence under all conditions, a larger ATX PSU with a bigger fan might be preferable.
