Corsair SF750 750W Power Supply

Corsair SF750 Platinum SFX Power Supply | Compact ATX 3.1 PSU

The Corsair SF750 power supply unit 750 W 24-pin ATX ATX Black delivers high-efficiency 750W output in a compact SFX form factor, making it ideal for small-form-factor gaming and workstation builds where space is at a premium.

Specification Overview

High-Efficiency Platinum Performance for Reliable Power

The 80 PLUS Platinum certification ensures the Corsair SF750 operates at up to 94% efficiency under typical loads, reducing heat output and lowering electricity costs over time. This level of efficiency means less wasted energy and a cooler-running system, which is particularly valuable in compact builds where airflow is limited.

Compact SFX Design with ATX 3.1 Compliance

Despite its small footprint (125 x 100 x 63.5 mm), this PSU supports ATX 3.1 specifications, providing stable power delivery for modern high-performance components including next-generation GPUs. The SFX form factor makes it perfect for mini-ITX cases where traditional ATX power supplies won’t fit.

Fully Modular Cabling for Clean Builds

The fully modular design allows you to connect only the cables you need, reducing clutter and improving airflow within your case. This is essential for SFF builds where every millimetre counts and cable management directly impacts system temperatures and aesthetics.

Comprehensive Protection and Reliability

Built-in protection features include overheating, over-current, over-power, over-voltage, and short-circuit protection. With a Mean Time Between Failures (MTBF) rating of 100,000 hours and FDB fan technology, this PSU is engineered for long-term, reliable operation in demanding environments.
