Product Overview
The CORSAIR SF1000 CP-9020257-UK provides desktop-class power in a compact SFX enclosure, making it an excellent choice for premium small-form-factor gaming PCs and compact professional workstations. Its 1000W continuous output includes up to 83.3A through the +12V rail, providing substantial power for flagship processors and high-performance graphics cards.
The power supply carries both 80 PLUS Platinum and Cybenetics Platinum efficiency ratings, reducing wasted electricity, operating heat, and cooling requirements. It is engineered for reliable continuous output at ambient temperatures reaching 50°C and incorporates 100% industrial-grade Japanese electrolytic capacitors rated for operation at up to 105°C. corsair.com
Official Intel ATX 3.1 compliance enables the SF1000 to meet the demanding transient-power requirements of modern computer hardware. PCIe 5.1 support and an included 12V-2x6-compatible 12+4-pin cable provide a direct connection for compatible graphics cards. Four conventional PCIe 6+2-pin cables support GPUs and expansion hardware using traditional power connections.
The fully modular CORSAIR Type 5 Micro-Fit cable system uses individually sleeved, flexible cables sized for space-restricted cases. Connecting only the necessary cables reduces clutter and can help improve airflow throughout the system. corsair.com
A 92mm fluid-dynamic-bearing PWM fan provides efficient cooling with minimal mechanical noise. Zero RPM mode stops the fan completely during low-to-medium workloads, allowing silent operation whenever active cooling is not required. corsair.com
