Power supply unit Lian Li EG0850 850 W SFX 20‑pin ATX 80 PLUS Gold Black

Lian Li EG0850 is an SFX power supply unit that delivers 850 W of continuous power with 80 PLUS Gold efficiency for compact desktop systems. The unit accepts 100–240 V AC input and provides a combined +3.3 V output up to 100 W. It uses a 20‑pin ATX motherboard connector with a 30 cm cable and includes CPU, PCIe, Peripheral (Molex) and SATA cables. The black housing and SFX form factor are intended for small form-factor builds that require reliable, efficient power delivery.

Advantages

The EG0850 combines a high power density in an SFX enclosure with 80 PLUS Gold efficiency to reduce energy losses and heat. Full modular sleeved cables with cable combs simplify cable routing and improve airflow inside compact cases. Built-in quality components such as German EPCOS bulk capacitors and Lian Li’s in-house soldered 12V alloy copper terminals contribute to stable voltages and long-term reliability. Compliance with ATX 3.0/3.1 standards ensures compatibility with modern motherboards and GPUs.

Suitable for

• Small form-factor gaming PCs and compact workstations
• Home and office compact desktops where space is limited
• Builds that require an SFX power supply with ATX 20‑pin connectivity

How to use

Install the EG0850 into an SFX-compatible case following the case and PSU manufacturer instructions. Connect the 20‑pin ATX motherboard cable to the motherboard’s main power header. Attach the necessary CPU, PCIe, SATA and peripheral cables from the modular connectors to your components. Verify AC input voltage is within the specified 100–240 V range before powering on. Ensure cables are routed to avoid obstructing airflow and that connectors are fully seated before first startup.

Recommendations

For optimal cooling and longevity in compact systems, use the sleeved modular cables with cable combs to maintain tidy cable management and ensure unobstructed airflow. Match the PSU’s ATX 3.0/3.1 features with compatible components and check connector pinouts if adapting from different form factors.
