Compact SFX power for small builds

The Lian Li SP850G.W is an 850W fully modular SFX power supply finished in white. It targets builders assembling compact systems that still demand high wattage for modern components. ATX 3.1 compliance and a native 12V-2x6 connector provide direct support for PCIe 5.0 graphics cards without adapters.

Thermals and efficiency in daily use

An 80 Plus Gold rating confirms over 90% efficiency at 50% load under 115V input, reducing waste heat. A single 92mm FDB fan handles cooling with a focus on low-noise operation. Active PFC maintains a power factor above .90 at full load across the 100-240Vac input range.

Build quality and cable implications

Fully modular cabling lets you install only the connectors required, keeping the interior tidy in tight chassis. The package includes two EPS cables at 600mm, two PCIe 6+2pin cables at 400mm, a 12V-2x6 to PCIe 6+2pin cable at 400mm, and a native 12V-2x6 cable at 420mm. A SATA cable chain covers drive power needs. Multiple protection circuits (OCP, OVP, OTP, OPP, SCP, UVP, NLP, SIP) guard the system.

Questions about this item

Will this SFX unit fit in a case that only accepts the 125 mm × 100 mm × 63.5 mm form factor?

Yes, the housing measures exactly 125 mm wide, 100 mm deep and 63.5 mm high, matching the standard SFX envelope.

Does the box include a native 12V-2x6 cable for a PCIe 5.0 graphics card, or do I need an adapter?

A dedicated 12V-2x6 cable 420 mm long is supplied, plus a 12V-2x6 to PCIe 6+2 pin cable 400 mm long, so no adapter is required.

How many EPS connectors are provided for a dual-CPU or high-end motherboard?

Two separate EPS cables are included: one 8-pin and one 4+4-pin, each 600 mm long.
