Lian Li SP1000P SFX power supply review: Exceptional power density in compact form

The Lian Li SP1000P SFX power supply delivers 1000 watts from a standard 100mm SFX form factor, showcasing exceptional power density achieved through advanced circuit topology and premium components. The unit features a flat copper strip transformer, ATX 3.1 certification for transient handling, and a ten-year warranty. The design includes an SFX-to-ATX mounting plate adapter, all-black cables with cable combs, and a compact, high-quality build with no manufacturing imperfections. Electrical performance, voltage regulation, ripple suppression, and protection features are all top-notch, though thermal management can lead to increased fan noise under high loads. Priced at around $185, the SP1000P targets a niche market of users requiring high power output in compact dimensions.
