SFX form-factor PSU for compact builds

This Lian Li SP series unit delivers 850W from a 125 x 100 x 63.5 mm enclosure, making it suitable for small-form-factor cases that cannot accept standard ATX power supplies. The fully modular design lets you connect only the cables your build requires, reducing internal clutter in tight layouts.

850W capacity with 80 Plus Gold efficiency

At 50% load under 115V AC input the unit exceeds 90% efficiency, so a typical gaming or workstation system runs with minimal waste heat. The 12V rail handles modern PCIe 5.0 graphics cards through the native 12V-2x6 connector, while dual EPS cables and two PCIe 6+2 pin leads cover high-end CPUs and a second GPU if needed.

Black finish, 92 mm FDB fan, ten-year protection

A 92 mm fluid-dynamic-bearing fan provides quiet cooling across the load range, and the supply carries OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP safeguards. Native 12V-2x6 and 12V-2x6-to-PCIe cables ship at 420 mm and 400 mm respectively, while SATA power leads use a 300 mm main run with 15 mm branches for drive placement flexibility.

Questions sur cet article

Will the 12V-2x6 cable on this 850W SFX unit work with an older GPU that only has 6+2 pin sockets?

Yes, the box includes a 12V-2x6 to PCIe 6+2pin adapter cable measuring 400mm, so you can connect legacy graphics cards without buying extra parts.

How can I verify the fan is running quietly after I install the PSU?

The 92mm FDB fan spins up only when needed; at low load it stays off, and under load it runs quietly — listen for a faint airflow sound rather than a click or whine.

Which cables come in the box and what must I purchase separately?

Included: 20+4pin ATX, two EPS 8pin, one EPS 4+4pin, two PCIe 6+2pin, one 12V-2x6, one 12V-2x6 to 6+2pin, SATA/PATA chain. No extra cables are required for a typical build.
