SFX 850 W Platinum unit

The Lian Li SP1000P.W is an SFX form-factor power supply rated at 850 W and certified to 80 Plus Platinum efficiency. It targets compact builds that still demand high output and low noise, and it ships with an SFX-to-ATX bracket for installation in larger cases as well. The unit follows the ATX 3.1 and PCIe 5.1 specifications and includes 12V-2x6 connectors for modern graphics cards. Fully modular cabling keeps the interior tidy.

Smart cooling under sustained load

A 9.2 mm FDB fan remains off until the load exceeds 40 %, delivering true zero-RPM silence during typical desktop work. Above that threshold the fan ramps up to maintain thermal headroom, and 105 °C-rated Japanese capacitors ensure stable voltage regulation during extended gaming or rendering sessions. Active PFC maintains a power factor above .95 at 115 V input, while the full protection suite — OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP — guards components through sudden power swings. MTBF is rated at 100 000 hours at 25 °C and 75 % load.

White finish, flexible cables, internal switch

The white chassis and braided-textured DC cables simplify routing in tight SFX layouts and improve airflow in any case. An integrated on/off switch on the C14-C13 mains cable lets you cut power without reaching the rear of the chassis, which is useful when the PSU is hidden behind panels. The compact footprint of 125 x 63.5 x 100 mm and a weight of 3.92 lbs make it easy to handle during assembly.
