    Very well built PSU! Has everything you'll need to build a modern desktop, has enough power for the latest video cards, very quiet too... I love Corsair products! Whatever they make, you know it's a high quality product

    This power supply is amazing, cable management is so much better with a fully modular PSU. It does not come with a 600w cable for higher tier gpus. You do however get enough PCIe cables to use the adapter from Nvidia, but I'd still recommend spending the $20-$30 on the 600w cable from Corsair online.

    I love this thing. I have so many fewer cables in my PC now that this is fully modular! And with my GPU upgrade, this thing has no issues keeping up either.

    I needed to max out my power output for my PC and this did the trick. The fully modular design is great for not having the rat nest of extra cables. It was a little longer than the 750 I originally had but just fit.

    I had purchased a different power supply that was also gold plus but was not modular. My motherboard had a strange CPU power configuration it required an 8 pin 12v connector and a 4 pin connector. Mine only had an 9 pin despite being a high voltage PSU. When I looked online everyone said that the 4 pin extra connector was for overclocking and was optional. The computer did run without the extra 4 pin connector but I was having some odd overheating issues with my 3090 GPU. After doing quite a bit of troubleshooting I decided to replace my PSU to get that last 4 pin connector. Now my 3090 has enough juice to spin the fans at maximum efficiency. Such an odd fix. I guess you really have to plug it in to make it work.

    It's quite big but fits in my NZXT H7 Flow case without issues. 1000watts plenty to power RTX 4080 and Intel 13900k
