    I was in a pinch and had to run out to the local Best Buy. Luckily they had one of these in stock. Only been using a couple of days as of now but, seems like it’s made well. Only time will tell.

    Bought because I needed someone better for my new build other than my 500 watt psu. This is great for my 12700k and 3070 combo!

    Coil whine

    Rated 5 out of 5 stars

    A little more expensive than others, but worth it.

    Excellent psu. When I first installed my AMD RX 6950 XT, I heard nothing but loud coil whine. When troubleshooting I found the noise wasn't coming from my gpu like I thought. It was coming from my EVGA 1000W psu. I swapped it out with this and now it's completely silent.

    I used to have a Thermaltake PSU and it was great but the issue was it didn't have enough ports on it. This one gets the job done.

    Coming from Corsair I'm sure this is a solid PSU, but uon receiving mine, one of the metal rings in the CPU connector was pushed in. Luckily there was an extra connector for this connection in particular, but I expected better quality control.

    The convenience if having a modular PSU is amazing allowing for better cord management without extra plugs hanging around.
