    For me 750w is more than enough for what I needed. I do like the modual design for easy change to a new or higher capacity without having to change your setup.

    Solid 750 watt supply. Quiet. Rather than having several amv Bilical cords prfixed to supply you add the cords you need. A nice to have.

    This was a recommended component to my kids new gaming computer they built. The first one was defective that we got from NewEgg. The one from Best Buy works perfectly.

    Good PSU but no auxiliary 2x2 CPU power cable

    This is a good PSU for the money and has plenty of room for expansion. The only downside is that it does not have a 2x2 power connector for my Z490 gaming motherboard. I powered the board and CPU just fine with a 4x4, but the 2x2 would be needed if I intend to do some serious overclocking of my i7.

    Works perfect only thing that was worrying me was that part of the box was crushed but it's packaged really well inside. Have had no problems with it. One reason for a 4 and not a 5 star was the box was damaged point to where I could put my fingers through the hole. Great Product

    So far this power supply is working well enough. I don't know if this is a issue related to my psu or something else but if i move the cables just right the power cuts, my system crashes, and i cannot power my system up until cables are moved around into i guess "better" spots? Wire managing has been difficult for this reason, but a few hours after installing i got my case closed and powered up with wires managed. Outside of this issue i have no reason to dislike this psu. Does its job for its size, have had no issues running a 10850k while overclocking an asus 1060. If you are planning to run more current gpus like a 2080/3080 or better with like a 10900k or a high end ryzen your probably better off getting a 1000w+ psu with atleast gold efficiency

    Working as intended! No problems setting up, and comes with all the cables I need. Wires a bit stiff, but nothing you cant manhandle.

    As usual an amazing Cordair quality, very low noise under load, I'm using it on an i7 9700 and RTX 3060 Ti without any issue at all.

    Has plenty of power, just wish there were a bit more instructions inside and a better way to ground myself on it since it has a non-conductive coating on it. Also, some of the cables could have been labeled a bit better especially for a first time PC builder.
