Lian Li, a name synonymous with sleek chassis and quality PC accessories, has announced its latest power delivery solution: the SP Platinum Series of fully modular SFX power supplies. Built specifically for high-end small-form-factor (SFF) enthusiasts, these new units deliver serious wattage in a compact frame, boasting 850W and 1000W options.
If you’re building a mighty mini-ITX rig, these PSUs are engineered to meet the demands of modern, powerful components while maintaining an impressive 80 Plus Platinum efficiency rating.
The Lian Li SP Platinum Series
These aren’t just small PSUs; they are fully future-proofed, complying with the very latest Intel ATX 3.1 and PCIe 5.1 standards. This compliance ensures they are ready to handle the next generation of power-hungry graphics cards right out of the box.
Lian Li has even engineered its own 12V-2×6 connector to handle the latest GPUs, featuring alloy copper terminals for better resistance and thermal tolerance. Plus, a dual-colour connector gives you a clear visual cue to make sure it’s seated correctly—handy for avoiding those dreaded melting issues!
Key Powerhouse Features:
- 80 Plus Platinum Certified: Up to 92% efficiency at 50% load.
- Next-Gen Ready: Fully compliant with Intel ATX 3.1 and PCIe 5.1 standards.
- Premium Build: Utilises 100% Japanese 105°C capacitors for longevity and stability.
- Comprehensive Protection: A full suite of safeguards including OCP, OVP, OTP, OPP, SCP, UVP, NLP, and SIP.
Silent Operation and Smart Utility
A powerful SFF build doesn’t have to sound like a jet taking off. The SP Platinum units feature a 92mm Fluid Dynamic Bearing (FDB) fan with a smart curve. Crucially, this fan stops completely when the load is at ≤40% or less, effectively making the PSU silent during low-usage tasks like web browsing or video streaming.
Lian Li has also thought about those tight SFF builds where the PSU is buried deep inside the case. Each unit comes with a unique extension power cord that includes an inline on/off switch. This means you can power down your system at the wall without needing to fumble around the back of a cramped case.
Cable Management Made Easy
Cable management is often the bane of an SFF builder’s existence. Lian Li has tackled this head-on by including super-flexible, braided modular DC cables. These cables are designed to bend easily around components, reducing clutter and helping to improve internal airflow—a must-have for a small case.
And if you want that small form factor power in a big case? No problem. The SP Platinum also ships with an SFX-to-ATX bracket for seamless installation in standard ATX enclosures.
What We Think
Lian Li seems to have hit the sweet spot here. The SP Platinum isn’t just a compact power source; it’s a premium, high-wattage PSU that is perfectly aligned with the needs of modern, high-end SFF gaming PCs. The inclusion of the latest ATX and PCIe standards, combined with smart features like the external on/off switch and incredibly flexible cables, makes this a serious contender for anyone looking to build a small but incredibly powerful machine. The choice of black or white colour schemes is a nice touch, too!
