I bought this back in June and had no reason to install it yet because I wasn’t able to buy a 30 series gpu until this moment. Open box to find the cable bags already ripped open and missing all the pcie cables. So now I can’t install my new gpu because I am missing the power cables for it. And unfortunately since I didn’t need to open it until now I’m outside the return window so I just have to leave a negative review at this point and move on and buy additional cables. Lesson. Always open your product when you buy them.

The product supplies power, it works, but with one major caveat, the power supply I recieved has horrendous coil whine, it sounds like there’s a rattlesnake inside my computer.

Time Bomb

Out of the box brand new, it smelled like burnt rubber/plastic, makes a loud ticking noise under heavy load, and the fan does not turn on at all. I think because the fan is not running, it's overheating and making this weird noise. Seasonic's manual states that if you press the button on the back, the fan will always run---that is not the case for me.
Thus, this PSU is a ticking TIME BOMB! BOOOOOM!!!!

Working as intended. I have used Seasonic for years and after having this specific PSU since 2021, it's still running strong. I haven't had any issues.

I ordered this becuase it has 3 PCie cables for my EVGA Geforce RT 3080 FTW3. The cables are easy to manage, it seems to work well.
