Fuente de alimentación Lian Li SP Series Platinum SFX totalmente modular PCIe 5.1 ATX 3.1 850W

The Lian Li SP Series Platinum SFX fully modular 850W power supply supports PCIe 5.1 and ATX 3.1 standards and is designed for compact high-performance systems. In an SFX form factor it provides Platinum-level efficiency, modern connector support and fully modular cabling to simplify installation and optimize airflow inside small-form-factor gaming PCs and workstations. The unit combines a compact chassis with features expected from current-generation PSUs to deliver stable power for CPUs and GPUs while complying with up-to-date power delivery requirements.

Advantages

The fully modular design allows precise cable selection for tidy builds and improved airflow. Platinum efficiency reduces wasted energy and heat, contributing to quieter operation and lower system temperatures. Native support for PCIe 5.1 and ATX 3.1 ensures compatibility with the latest graphics cards and motherboard power delivery standards. The SFX compact footprint enables installation in space-constrained cases without sacrificing power headroom for high-end components.

How to use

Install the power supply into a compatible SFX or SFX-to-ATX adapter bay according to the case manufacturer’s instructions. Connect only the cables required by your configuration, starting with the 24-pin motherboard connector and CPU power cable, then add the PCIe power connectors for the graphics card and any peripheral SATA or Molex connectors as needed. Ensure connectors are fully seated and routed to maintain clear airflow paths. Configure the system BIOS/UEFI settings for power and fan control if required by your motherboard.

Recommendations

Choose appropriately rated PCIe power cables provided by the manufacturer when installing high-power graphics cards. For best thermal performance, maintain unobstructed airflow in the case and avoid routing multiple heavy cables across intake or exhaust paths. Verify compatibility with your case’s SFX mounting and, if using an adapter, confirm secure mechanical fit and adequate ventilation.
