    i mean the mb 24 pin was a little stiff, but was able to fit in on my apevia genesis case. works great so far with my 3060 (ik a bit overkill but it was only 10 dollars over the 650 so i just went for it).

    Ive done a lot of custom pc builds over the years and Corsair has always been my go-to brand for PSUs. The quality is always top notch, and Ive never had a single one fail or arrive with issues. Fully modular is the way to go to keep everything as neat and tidy and clean looking as possible, though you do pay a little more for that option, its worth it to not clutter your case with excess cabling that will hinder your ideal airflow path.

    Soon as I plugged it in and tried to boot, POP. Smoke out of the main 24PIN ATX cable. Shouldve looked at the recent reviews, ah well. 2 HDs arent registering as of writing this, but everything else is fine otherwise. Never again. Hopefully the next few buyers will have better luck than I.

    Easy to install and works great. Some NZXT cases might have issues with installation (screw holes not lining up).

    Excellent for my white build. It had coil whine at first but went away after a while. Wish Corsair builds more white PSU new models
