Fuente de alimentación Lian Li SP Series Platinum SFX totalmente modular PCIe 5.1 ATX 3.1 1000W

The Lian Li SP Series Platinum SFX fully modular PCIe 5.1 ATX 3.1 1000W power supply is designed for compact high-performance desktop systems. In an SFX form factor, it provides up to 1000W of continuous output, fully modular cabling for simplified installation and cable management, and support for the PCIe 5.1 power specification while complying with ATX 3.1 requirements. This combination makes it suitable for small-form-factor gaming PCs and workstations that require stable power delivery for modern GPUs and CPUs without sacrificing internal space.

Advantages

The SFX form factor allows installation in compact cases while delivering a high 1000W power capacity. Fully modular cables reduce clutter and improve airflow in confined builds, and native support for PCIe 5.1 ensures compatibility with the latest graphics cards that use the newer power connector standard. Compliance with ATX 3.1 means the supply meets current standards for power delivery and system compatibility. Overall, the unit targets stable, reliable power delivery for demanding components in space-constrained systems.

Suitable for

• Small-form-factor gaming PCs that use modern high-power GPUs
• Compact workstations for content creation and 3D workloads
• HTPCs or compact desktops requiring high wattage and tidy cable routing
• System builders upgrading to PCIe 5.1–compatible graphics cards

Key specifications

• Form factor: SFX
• Maximum output power: 1000W
• Cabling: Fully modular cable system
• PCIe power: Supports PCIe 5.1 power specification
• Standard compliance: ATX 3.1
• Target use: Compact high-performance desktop systems

How to use

Install the power supply into a compatible SFX or SFX-to-ATX adapter bay according to the case and motherboard layout. Connect only the modular cables required for the system components to maintain clear airflow and reduce internal clutter. Use the provided PCIe 5.1–compatible cable(s) for GPUs that require the new connector specification and ensure all connections are fully seated before powering on. Verify motherboard and component power requirements against the supply’s capabilities during assembly.

Recommendations

For reliable operation in compact systems, route cables to avoid blocking intake or exhaust fans, confirm compatibility with your case’s SFX mounting points, and follow manufacturer guidance for PCIe 5.1 connector usage. Regularly check for secure connections and proper ventilation to maintain stable power delivery and component longevity.
