Lian Li SP850 White 850W SFX Power Supply Review

The Lian Li SP850 packaging is very much like what we saw from the SP750. So, the packaging is small but well put together once more. The front of the package has a bit of information about this unit and a picture of the power supply itself on a black smoky background (I hope that isn’t a warning……..). Besides a few advertising points, we see an 80 Plus Gold seal and a warranty seal. When we check the 80 Plus website we find that this unit was not listed at the time of testing.

The rear of the packaging has gone minimalist but it does have the dimensions of the unit and the cable count (reproduced below) including the new 12VHPWR/PCIe 5.0 adapter cable. The side of the packaging has an efficiency graph, noise graph, and power label (reproduced below). The rest of the sides of the packaging just contain some random advertising repeated from the front of the packaging. Lastly, the SP850 carries a 5-year warranty.

LianLI SP850 Connector Count

The SP850 is advertised as being a single 12v rail power supply with a capacity up to 70A (or ~99% of the unit’s capacity) if necessary. The minor rails (5v and 3.3v) have a capacity of 20A each and the combined capacity of those two rails is 100W. Combined with these outputs, we find that this unit has 3 PCIe connectors, 8 SATA connectors, 4 Molex connectors, and 1 12VHPWR/PCIe 5.0 connector.

Once we open the Lian Li S850 packaging we find the power supply, mounting screws, modular cables, the power cord, and the “user manual”. The “user manual” covers just this model and it is just one sheet of paper folded in half. The “user manual” contains the graphs and cable numbers we found on the packaging and that is about it. Let’s move on to the unit itself now.
