This article covers Lian Li SP850 80 Plus Gold Performance SFX フォームファクター電源 ブラック.

Overview

The Lian Li SP850 is an 80 Plus Gold certified SFX form factor power supply unit. Designed for compact PC cases, it delivers high power efficiency and a small footprint without compromising on performance. With a rated output of 850W, it provides ample headroom for mid-range to high-end gaming PCs and creator workstations. The fully modular braided cable design helps maintain clean airflow inside the chassis and simplifies cable management. This PSU features a dedicated 12VHPWR connector, enabling direct power delivery to PCIe 5.0 graphics cards. The 92mm cooling fan supports a ZERO RPM mode, keeping the system silent under low loads. High-quality Japanese capacitors are used internally, ensuring long-term reliability and stable power output. In the SFX PSU market, options above 750W are relatively limited. The Lian Li SP850 stands out by offering 850W capacity with Gold efficiency and a comprehensive connector set, making it an excellent choice for high-performance small-form-factor builds.

Compatibility Guide

The SP850 conforms to the SFX form factor and fits into any SFX-compatible PC case. It is widely used in Mini-ITX cases and some Micro-ATX cases. For ATX cases, an SFX-to-ATX mounting bracket may be required. Connector-wise, it includes a 24-pin ATX main connector, a 4+4-pin EPS CPU connector, multiple 6+2-pin PCIe connectors, and a 12VHPWR connector. This makes it compatible with the latest GeForce RTX 40 series and Radeon RX 7000 series graphics cards. Sufficient SATA and peripheral connectors are also provided for storage drives and fan hubs.

Product Info

The Lian Li SP850 was released in late 2022. It holds an 80 Plus Gold certification, achieving up to 92% efficiency. It is positioned as a mid-to-high-end SFX PSU, targeting enthusiasts building compact yet powerful systems. The unit comes with a 7-year warranty.

Best Use Cases

Small-form-factor gaming PCs: Ideal for Mini-ITX builds where space is tight but high performance is required. The 850W capacity comfortably supports an RTX 4070 Ti or RX 7800 XT paired with a Core i7 or Ryzen 7 processor. Silent PC enthusiasts: The ZERO RPM fan mode keeps the PSU fan off during low loads, making it suitable for quiet home or office environments. * Clean cable management: The fully modular braided cables allow users to connect only the necessary cables, resulting in a tidy interior and improved airflow.

Things to Consider

Due to its SFX form factor, the SP850 uses a smaller 92mm fan, which may produce more noise under heavy load compared to larger ATX PSUs. If your case does not natively support SFX, you will need an adapter bracket. While 850W is sufficient for most gaming builds, pairing it with a flagship GPU like the RTX 4090 and a top-tier CPU (Core i9/Ryzen 9) may push the limits; a 1000W unit would be a safer choice for such extreme configurations.
