Power Supply LIAN-LI SP850P SFX white SP0850P-W 80 Plus Platinum 850W

Lian-Li SP850P 850W Platinum SFX White Power Supply

The Lian-Li SP850P is a compact SFX-format power supply aimed at Small Form Factor systems that still demand real output. This white 850W version blends Platinum-grade efficiency with support for the ATX 3.1 and PCIe 5.1 standards, making it well suited to a strong build in a small case with a clean, bright look.

Power & efficiency

The small SFX body packs an 850W output, so even tight enclosures can drive a demanding CPU and graphics card. The 80 PLUS Platinum and PPLP Platinum certifications deliver efficiency reaching up to 92% at 50% load, cutting wasted heat and helping the unit run economically and quietly. Precise voltage regulation helps keep components stable even when the load spikes quickly.

Cables & connectors

The unit is ATX 3.1 ready and arrives with a reinforced 12V-2x6 cable that supplies up to 600W, intended for the newest graphics cards. The architecture is fully modular and uses braided leads, so you can attach only the cables you need and keep order along with good airflow. To fit the unit into a wide range of chassis, an SFX-to-ATX adapter is also included in the box.

Reliability & cooling

Cooling duty falls to a smart 92 mm fan with an FDB bearing, tuned for quiet, temperature-managed running. The unit's longevity rests on genuine Japanese Rubycon capacitors rated at 105°C. A full protection set covering OPP, OVP, SCP, OTP, UVP and UCP adds a safety layer against overvoltage, overload, short circuit and high temperature.
