Lian Li SP850 850W

This is a 850W unit with 80+ Gold efficiency certification and full cabling. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. It uses the SFX form factor — confirm your case lists SFX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $144.99 price tag places it squarely in high-end territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Lian, with terms that vary by region.
