Compact SFX-L power for small builds

The Corsair SF850L CP-9020245-NA is an 850 W SFX-L unit built for compact systems that still demand full ATX 3.0 compliance. Its 130 mm length fits many small-form-factor cases while the fully modular Type 5 micro-fit cables reduce clutter and improve airflow. The 120 mm rifle-bearing fan supports Zero RPM mode so the supply stays silent at low loads.

Sustained delivery with 80 PLUS Gold efficiency

Rated for continuous 850 W output, the unit holds 80 PLUS Gold certification at up to 90 percent typical efficiency and carries Cybenetics Standard noise certification. Japanese 105°C-rated primary electrolytic capacitors keep voltage regulation stable during long gaming or render sessions. The single 12 V rail can supply the full 850 W to modern GPUs without rail-balancing concerns.

Check case clearance and GPU cable needs

Verify that your chassis accepts a 130 mm deep SFX-L power supply and that the 24-pin ATX, dual 8-pin EPS, and PCIe cables reach your motherboard and graphics card. The box includes one native 12+4 pin 12VHPWR cable for PCIe 5.0 GPUs such as RTX 40 series cards plus two 6+2 pin and one 6+2 pin pigtail cable for older connectors. Input range is 100-240 V at 47-63 Hz.
