    Nice upgrade

    Upgraded my son’s gaming computer from a Corsair 650 to this bad boy. Great reviews online. I love that it is modular and you can leave out any cables not needed. Definitely helps with cable management. It is also nice that it has two CPU power cables for the larger ATX boards. Platinum rated and it has a nice zero RPM mode so you do not even have the fan on if it isn’t needed. Also one of the few PSUs with RGB fan if you are looking to add color to your rig. It is big though, being 1000w, so make sure you have space for the unit and the cables being plugged in behind it.

    Does it's job. Relatively quite. Using it with an RTX 4080 Super, and have had no issues.
