PLATINUM POWER FOR SFF BUILDS


SMALL AND MIGHTY
Don't let the size fool you – this SFX power supply packs 80 PLUS Platinum-rated power, perfect for the most power-dense small form-factor PCs.

50°C CONTINUOUS OPERATING TEMPERATURE
Ensures reliable power for your SFF PC, even under high-stress conditions.

105°C-RATED CAPACITORS
Built with 100% Industrial-grade, 105°C-rated Japanese electrolytic capacitors for unwavering power and reliability.

ATX 3.1 CERTIFIED
The ATX 3.1 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, SF Series PSUs are formally certified for ATX 3.1 compliance.

PCIe 5.1 12V-2x6 GPU cable included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.

QUIET OPERATION WITH ZERO RPM MODE
A fluid dynamic bearing cooling fan keeps noise to a minimum, with Zero RPM mode to eliminate fan noise completely at low to medium loads.

FULLY MODULAR TYPE 5 MICRO-FIT CONNECTORS
Connect only what you need, with flexible cabling to take up less space for tidy cable management in small cases.
