Lian Li SP850 SFX Form Factor Power Supply

While standard PC chassis designs offer a plethora of power supply choices for consumers, I think it’s fair to say that when it comes to SFF and SFX builds your choices are often, comparatively speaking, a lot more limited. – With the release of the new Lian Li SP850 SFX, however, this definitely seems to be looking to offer itself as a total solution.

Not only does it offer an impressive 750 watts of power and 80-Plus Gold efficiency in a remarkably small package, but it also comes with a PCIe Gen5 power connection right out of the box!

We should start by noting that the SP850 SFX is available in either black or white designs and I would concede that Lian Li doesn’t appear to be making much of a fuss about this particular point. Black PSUs are plentiful, white?… Not so much. Still, though, you actually have a choice here and with both offering the same features at the same price point, the aesthetic choice really is yours to make!

On the whole though, while coming as an SFX design, Lian Li has packed an impressive array of features that definitely makes this an excellent choice on the surface. Put simply, I think this design could give a standard (and twice as large) PSU a solid run for its money and performance!
