The CORSAIR RM750e is a fully modular power supply that delivers clean, stable, and quiet power for modern PCs. With Cybenetics Gold efficiency (up to 92%), it meets the demands of high-end GPUs and CPUs while keeping noise low.

This PSU is a beast. Fully modular, quiet, and the native 12V-2x6 cable is great for my RTX 4070. Installation was easy with the included cables. No coil whine, no issues. Highly recommend.
Performance is excellent, but the cables are a bit short for a full tower case. I had to stagger them to reach the top of my motherboard. Otherwise, it's a quality unit.
My old RM650 served me well, but I needed more power for a new GPU. The RM750e is perfect. The ATX 3.1 certification gives me peace of mind, and the 105°C capacitors feel high-end. It's also super quiet – I can't hear it at all.
I'm running a Ryzen 7 7800X3D and an RTX 4070 Ti Super. This PSU handles everything without breaking a sweat. The 12V-2x6 cable is a dream – no adapter needed. The white finish matches my setup. Great value.
The PSU works fine, but the fan makes a noticeable buzzing sound under load. It's not unbearable, but it's not silent as advertised. Maybe I got a defective unit. Other than that, it's reliable.
No issues. Does the job.
The PSU is great, but the 24-pin cable is a bit stiff, which made routing difficult. I also wish the included SATA cables had right-angle connectors. But performance is top-notch.
I'm a stickler for efficiency, so the Cybenetics Gold rating was a big selling point. The PSU runs cool and quiet, and my electricity bill hasn't spiked. The fully modular design makes cable management a breeze. This is my third Corsair PSU, and they never disappoint.
I've used Corsair PSUs in all my builds. This one is just as reliable as the rest. The ATX 3.1 support is future-proof, and the all-white look is clean. The 12V-2x6 cable is flexible and easy to manage. Highly satisfied.
This PSU is nearly silent under normal load. The only time I hear it is during heavy gaming sessions, and it's just a gentle hum. The cables are durable, and the modular design is convenient. Great job, Corsair.
I was a bit skeptical about the fan noise, but it's actually very quiet. The 750W is more than enough for my mid-range setup. The fully modular cables made installation easy. The white color is a nice plus. I'm very happy with this purchase.
I really wanted to like this PSU, but it just stopped working after a few months. My PC wouldn't turn on, and after testing the PSU, I confirmed it was dead. I've since replaced it with a different brand. Maybe I got a lemon, but I'm disappointed.
