Lian Li added two new SFX-L form factor power supplies to its lineup; the 80Plus Gold certified PE-550 and the 80Plus Platinum PE-750. Both models offer a fully modular cable design, flat ribbon cables, and a 120mm smart fan that remains idle when load is under 30 percent.
Lian-Li Industrial Co. Ltd is pleased to announce its two high-wattage SFX-L PSUs: the PE-550 and PE-750. These fully modular, small form factor power supplies are excellent choices for small form factor builds using powerful, high-end hardware.
The New SFF PSU: Big Power in a Small Box
The most general trend in electronics is miniaturization: the smaller the better. This is reflected in nearly every facet of PC hardware and cases are no different. Small form factor, mini-ITX cases are popular and for a reason; if one can have a smaller footprint without compromising performance, why not? The PE-550 and PE-750 provide 550W and 750W respectively – more than enough to drive even multi-GPU gaming PCs.
High Energy Efficiency, Low Noise Power Supplies
The PE-550 is 80Plus Gold-rated for a maximum 89.5% efficiency; the PE-750 is 80Plus Platinum-rated for a maximum 92% efficiency. Both use a near-silent 120mm smart fan and minimize noise by operating fanlessly when output power is below 30%. Both PSUs use a single 12V rail design for the best possible stability under heavy system load, matched with myriad protection features to ensure reliable operation.
Space-saving Specifications for Small Form Factor PCs
Both SFX-L power supplies use modular cables to eliminate clutter – users need only connect the cables they need without having a clump of extra wires. They also use flat ribbon cables for a cleaner, more organized aesthetic. This cable style makes builds look more polished and professional. Both PSUs include an adapting plate for ATX-sized mounts.
