Build your next high-performance PC with confidence: the Corsair SF1000 delivers a full 1000 watts of power in a compact form-factor, with premium efficiency, future-proof compatibility and ultra-tidy modular cabling. Engineered for the most demanding systems — SFF builds, high-end gaming rigs, or workstations — this 1000 W PSU supports the latest standards such as ATX 3.1 and PCIe 5.1 for ultimate reliability now and in the years to come. 

Key Features

• 1000 W full power output — ample head-room for high-end CPUs & GPUs.

• 80 PLUS Platinum certified efficiency — helps reduce energy waste, lower heat and quieter operation. 

• ATX 12V v3.1 compliant & PCIe 5.1 ready — supports next-gen graphics and power demands, and handles transient power spikes. 

• Fully modular design with Corsair Type-5 Micro-Fit connectors and individually sleeved cables — for easy cable management and clean builds.

• Compact SFX form-factor (125 × 100 × 63.5 mm approx.) — fits into smaller cases while offering full power.

• Silent operation: 92 mm PWM fluid-dynamic bearing fan with Zero-RPM mode at low to moderate loads — quiet systems assured. 

• Built for durability: 105 °C-rated Japanese capacitors, single +12 V rail design for stability and high load tolerance. 

• Includes SFX-to-ATX bracket — allows installation in larger ATX-format cases too.

• Extended 7-year warranty — peace of mind for long-term usage. 

Why This PSU Stands Out

In today’s PC-market, many power supplies offer high wattage, but few combine compact size, top-tier efficiency, and modern standard compliance as the SF1000 does. If you’re building a small-form-factor (SFF) rig, a powerful gaming/creator system, or simply want a PSU that won’t need replacing when your next-gen GPU or CPU comes along, the SF1000 is built for exactly that. With future-proofing for PCIe 5.1 devices and strong, efficient output, you’re buying more than just power — you’re buying longevity and quality.

Ideal Applications

• SFF builds where space is limited but high performance is required.

• High-end gaming PCs with flagship NVIDIA/AMD graphics cards (that often require 12VHPWR or high current rails).

• Creator workstations or streaming rigs where reliability and noise-control matter.

• Anyone wanting to upgrade from older gold-rated PSUs to a premium platinum tier build.

Technical Snapshot

• Output: 1000 W total, single-rail +12 V design (~83.3 A) 

• Form Factor: SFX size ~125 × 100 × 63.5 mm 

• Efficiency: 80 PLUS Platinum certified; also observed Cybenetics Platinum rating in independent tests. 

• Cable & Connectors: fully modular; includes standard 24-pin ATX, 2× EPS/CPU, multiple 6+2-pin PCIe + 12+4-pin (12VHPWR) connector for high-end GPUs.

• Cooling & Noise: 92 mm fan, FDB bearing, Zero-RPM mode under lighter loads for near-silence. 

Important Notes

• While compact, ensure your PC case supports SFX (or SFX-to-ATX bracket) and allows for cable routing, especially if you have thick or custom cables.

• For builds in South Africa, check input voltage compatibility (100-240 V) and plug type before purchase/installation.

• Even though this PSU is “quiet” under moderate loads, the actual system noise will also depend on GPU/CPU cooling and case airflow.

• Make sure your GPU’s power connector (if 12VHPWR) is supported; this unit comes ready for PCIe 5.1 standards.

• Ensure your case ventilation is sufficient—1000 W at high loads still generates heat, so airflow matters.

The Corsair SF1000 is a premium-grade 1000 W power supply that brings together compact size, high efficiency, rich connectivity, and modern power standards. Whether you're building an SFF gaming beast, a creator workstation, or upgrading your rig for next-gen graphics cards, this PSU offers the reliability and performance you need. Invest now for power that won’t hold you back tomorrow.
