Perfect for flagship small form-factor (SFF) gaming PCs, high-performance Mini-ITX builds, compact workstations with power-hungry components, portable enthusiast LAN party rigs, premium HTPC (Home Theater PC), SFFPC enthusiast builds, Fractal Terra/Node cases, DAN Cases, Ghost S1, Louqe Raw S1, FormD T1, and any build requiring maximum flagship-tier power in minimal space with ATX 3.1/PCIe 5.1 support. The Corsair SF Series SF1000 is an extraordinarily power-dense 1000W SFX power supply—one of the smallest 1000-watt power supplies ever made and the only 1000W SFX PSU that doesn't have fans turn on at low loads while maintaining true SFX size and full 1000W capacity—perfect for powering the most cutting-edge small form-factor PCs with flagship components in ultra-compact cases. Despite its tiny true SFX form factor measuring just 100mm x 125mm x 63.5mm (one of the smallest 1000W PSUs in the world), this powerhouse delivers a full 1000 continuous watts of clean, stable power on a single +12V rail (83.3A), ready to handle the most demanding flagship CPUs like Intel Core i9 or AMD Ryzen 9, paired with top-tier graphics cards like NVIDIA RTX 40-series including RTX 4090, or AMD RX 7000-series—all in cases smaller than a shoebox. Updated to the latest ATX 3.1 standards with PCIe 5.1 readiness, the SF1000 includes a native 12V-2x6 (16-pin, also called 12VHPWR or 12+2-pin) connector capable of delivering 600W for modern graphics cards such as the NVIDIA GeForce RTX 40 Series, with support for 2x transient power excursions resisting power spikes from PCIe Gen 5 platforms—making this the ultimate SFX PSU for next-gen GPU builds. The SF1000 achieves 80 PLUS Platinum certification with up to 92% efficiency and Cybenetics Platinum rating, delivering steady power output while significantly reducing power consumption from the wall, generating less heat, and lowering electricity costs over time—critical efficiency in small cases with limited airflow where every degree matters. The Cybenetics Standard++ noise rating and ultra-quiet 92mm PWM fluid dynamic bearing (FDB) fan with Zero RPM Mode ensures quiet operation—the fan stays off entirely during idle, light, and even medium loads, providing near-silent operation perfect for HTPCs and quiet desktop environments, then intelligently ramps up only when needed for high loads with precise PWM fan speed control and powerful cooling with low-noise operation. Built with premium 105°C-rated Japanese electrolytic capacitors for unwavering power and reliability, and rated for continuous full-load output at 50°C ambient temperature, the SF1000 delivers superb electrical performance and reliability even under high-stress conditions in thermally challenging small form-factor cases with restricted airflow where temperatures naturally run higher. Fully modular Type 5 Micro-Fit PSU connectors with flexible, low-profile cabling allows you to connect only the cables your SFF system needs, taking up less space for tidy cable management and compatibility in small cases, dramatically reducing cable clutter inside your compact case and promoting better airflow for improved cooling—essential in tight SFF builds where every millimeter matters. The high-quality finish and neutral black color design delivers professional aesthetics that look great in windowed SFF cases. The included SFX-to-ATX adapter bracket enables installation into ATX cases for more cable space in larger systems, providing flexibility if you want to move your build between SFF and ATX enclosures. Compatible with ATX12V v3.1, EPS 2.92, and SFX12V standards, the SF1000 uses a single +12V rail with all necessary protections for safe operation. Corsair has removed the -12V rail from this PSU which helps increase efficiency and reduce costs without impacting compatibility. Multi-GPU ready despite compact size, supporting both SLI and CrossFire configurations for users who want dual-GPU setups in SFF cases. Comprehensive protection circuitry guards against over voltage, under voltage, over current, over power, short circuits, and over temperature conditions, protecting both the PSU and your valuable components in the confined space of small cases. With a robust 100,000-hour MTBF (Mean Time Between Failures) rating and backed by CORSAIR's industry-leading 7-year warranty with world-class support, the SF1000 delivers peace of mind and reliable performance for seven years through multiple SFF builds. Available at MSRP $239.99-$269.99 (currently on sale for $199.99 in some regions), this is the ultimate SFX PSU for serious SFF enthusiasts who demand flagship-tier power. Ideal for flagship SFF enthusiasts, high-end Mini-ITX builders, compact gaming rigs with RTX 40-series GPUs, portable workstations, and anyone who demands absolute maximum power in the smallest possible footprint with ATX 3.1/PCIe 5.1 support, the SF1000 provides abundant power headroom for flagship components, Platinum efficiency, ultra-quiet Zero RPM operation, and proven reliability. Don't let the size fool you—this SFX power supply packs massive 80 PLUS Platinum-rated power perfect for the most power-dense small form-factor PCs. Upgrade to compact, efficient, flagship-tier, and near-silent premium power with the Corsair SF Series SF1000.
