    I rebuilt an existing desktop computer, replacing 8 year old components. This was kind of an almost afterthought, but glad I swapped it in!

    I recently had gotten a RTX 3080 and realized that it wasn't going to work in my PC without a beefier PSU. After researching for what I needed, I found this on BestBuy and decided to give it a try. It's much nicer than my old one and the modular ability to use only the cables I needed was perfect. Every connection I needed was available. The only issue I had is that one of the ports actually allowed me to plug in a cable the wrong way, which is why my initial install did not work. It was hard to see because it looks like I was doing it right, but after switching it out, it worked fine. I guess look out for that. Good quality PSU.

    Nice power supply that packs a punch of 1000W. Comes with tons of cables so you'll be able to plug in all of your peripherals. No issues at all, works great. Not a bad price either.

    Loving this PSU, quiet and powerful, fan rarely turns on this provides enough power for a 1080, 3060 and 3080 at full load! only complaint is I wish they would have included a couple more PCIe cables.

    I looked for months to find a 1000 watt psu, and thanks to Best Buy i finally found a great deal on a well known brand for a good price. $189.99 is a awesome deal when most are at a minium $250-$300. Gold rated at that. I can now overclock my RTX 3090 and 5900x as much as i want with no worries.

    Bought this because my old power supply was on the edge of murdering my entire build which I didn't want to risk for any longer. My first impression was how insanely quiet it is, my computer is almost dead silent now with this. Turns out my old PSU was what was making all the noise, as I have Noctua fans installed in my pc. I would strongly recommend this to anyone who is in the market for a new psu or building a new rig.

    Was a little difficult to feed the cables through since they were grouped together, more an issue with the case design. Worked great and continues to perform amazing.
