The CORSAIR SF750 (2024) is a fully modular SFX power supply that packs high-wattage 80 PLUS Platinum-rated power into a compact 125mm form factor, perfect for small-form-factor (SFF) builds. It is ATX 3.1 compliant and PCIe 5.1 ready, meaning it can handle the transient power spikes of modern GPUs and support the latest power connectors. The included 92mm PWM fan uses a fluid dynamic bearing for quiet operation, and Zero RPM Mode stops the fan entirely at low loads for silent computing.
Built with 105°C-rated Japanese capacitors, the SF750 delivers reliable, stable power even under heavy system stress. The fully modular, Type-5 Micro-Fit connectors allow you to use only the cables you need, keeping cable management tidy in tight cases. With up to 750W of output, it's ideal for high-performance SFF gaming PCs, workstation builds, and ITX enthusiasts who want no-compromise performance.
The SF750's cooling system is designed for quiet operation. The fan starts spinning only under load and adjusts its speed based on a temperature-controlled fan curve. When power draw and temperature are low, the fan remains off (Zero RPM Mode) for silent operation. As load increases, the fan kicks in gradually, ramping up to keep components cool. The default fan curve balances noise and thermals, but you can customize it via CORSAIR iCUE (if using a compatible motherboard header) or rely on the power supply's automatic control. The fan turns on around a specific power threshold; for most systems, it stays off during light use and spins up during gaming or rendering.
The exact temperature and load thresholds vary based on internal thermals. At typical desktop loads, the fan may not spin at all. During intense sessions, you'll hear a gentle hum as the fan increases speed. The fluid dynamic bearing ensures low noise even at higher RPMs, keeping your SFF build quiet under pressure.

The SF750 (2024) supports Intel ATX 3.1 and PCIe 5.1 specifications, ensuring compatibility with the latest GPUs and future proofing your build. Its Type-5 Micro-Fit cables are individually sleeved for easier routing in cramped spaces. The power supply has a 7-year warranty and is backed by Corsair's reliable support. For non-modular builds, the included cable set covers all common needs, from motherboard power to SATA drives.
The fan stays off at low loads when internal temperatures are below a threshold, enabling silent operation. It spins up as needed to maintain cooling.
The fan speed is controlled by temperature and load. It ramps up gradually, and you can customize the curve using compatible software if your motherboard supports it.
It's designed for PCIe 5.1 graphics cards, providing up to 600W to a single cable. It's backward compatible with PCIe 5.0 cards.
Yes, the included bracket lets you mount it in larger cases that accept ATX or SFX. However, it's primarily designed for SFF builds.
I built a small form factor PC with the NR200P and this PSU fit perfectly. The cables are long enough and the fan is silent even under load. No issues with stability and the ATX 3.1 support future-proofs my system.
Swapped out an older unit for this Corsair SF750. Build quality feels excellent, and the 92mm fan barely spins under normal use. My system runs cool and stable. Highly recommended for any quality ITX build.
Works great, no complaints.
This is a high-quality power supply. It's very quiet and the cables are nice. The only downside is the premium price, but you get what you pay for.
I've been using this in my gaming rig for over a month now. The fan is inaudible during normal use, and even under stress tests it stays quiet. My 13700K and 4080 run flawlessly. Worth every penny.
This PSU works well and is quiet, but the cables are pretty stiff, which made routing in my small case a bit of a hassle. Otherwise, it's solid.
If you're building a high-end SFF PC, this is the one. It handles my 7950X and 4090 with ease. The fan noise is negligible. I love the 12VHPWR cable included for the GPU. Perfect.
For the size, it's amazing. I was a little worried about running a 4090 on 750W, but it's been rock solid. The 80 Plus Platinum rating means lower power bills, too.
The SF750 has been great so far. It runs quiet, the cables are of good quality, and it has enough connectors for my setup. Just be careful with the stiff cables if you have a tight build.
Unfortunately, my unit had noticeable coil whine under load. The performance is fine otherwise, but it's annoying. I expected better from Corsair. Had to RMA.
