LC-Power LC300SFX V3.21 250W SFX Power Supply

250 W / 300 W63 × 125 × 101 mm4-pin CPU · 6-pin PCIe

The LC-Power LC300SFX V3.21 is a compact SFX power supply for an office or home PC with a matching PSU bay. Its rated output is 250 W, with a separate 300 W maximum peak rating. The fixed wiring provides four SATA plugs as well as older PATA and floppy power connections.

Compatibility — check before buying:
Plan around the 250 W output and the manufacturer’s 190 W combined +12 V limit. Check the SFX mounting dimensions, 35 cm motherboard/CPU/PCIe leads and your component connectors; a mains lead is required separately.

Key Features

 
Compact SFX housing
The 63 × 125 × 101 mm housing fits installations designed for this SFX size. A Mini-ITX motherboard alone does not establish PSU mounting compatibility.
 
Four SATA power plugs
Two SATA plugs sit at 35 cm and two at 50 cm, with PATA plugs at 65 cm and a floppy plug at 80 cm. Check those distances against your drive positions.
 
Active PFC and efficiency
LC-Power specifies active PFC and efficiency greater than 85%. This efficiency statement is separate from an 80 PLUS certification claim.
 
80 mm fan cooling
An 80 mm fan and rear ventilation grille cool the compact unit. Allow room for airflow and the permanently attached cable harness.

What's in the Box

Frequently Asked Questions

Does LC300SFX mean 300 W continuous output?
No. The manufacturer lists 250 W output and 300 W maximum peak. Use the 250 W rating and the individual rail limits when assessing the build.
Can it directly power an 8-pin CPU or 8-pin graphics socket?
Its native CPU plug is 4-pin and its PCIe plug is 6-pin. Check the component manufacturer’s requirements; these are not native 8-pin connections.
Is a mains lead supplied?
No. The manufacturer datasheet explicitly excludes the power cord. Arrange a suitable lead separately.

Buyer’s Guide

Buy it if

Your SFX case and low-power system match its dimensions, plugs and rail limits.

Skip it if

You need 300 W sustained output, native 8-pin connections or 110 V input.

Also consider

An SFX PSU with the required sustained output and native connectors.
