    Great power supply that has plenty of juice for a modern gaming system. Modular cables lets you decide what all needs to be plugged in and makes things easier to cable manage.

    I purchased this power supply to replace my stock HP supply. HP has a proprietary power supply and this is the only one that I found that would replace it. It fit perfectly in my case and definitely produces enough power for my upgrades!

    I needed a PSU upgrade once I got a new GPU. This fully modular PSU is amazing. I haven't had a single hiccup since swapping this in and also the great price at Best Buy for an 80Plus Gold rated one!

    Great PSU, It is better to have more than less. I run 2 SSds, a 12700K and a 12GB 3080 so a lot of power being pulled. Only concern is if your fun requires a PCIe cables the PSU only comes with 2. Your options are get a 3rd one or use the extra ones conjoined to the other 2, like I did. That said power is good at full OC!

    Best investment I made for my PC. I had to purchase the 12VHPWR cable separately but it’s all good. PC been running smoothly since I replaced the power supply it came with for this one.

    You cannot go wrong with a Corsair PSU. This is the 2nd one i have bought for my 2 gaming PC builds. This is strong enough to run a EVGA 3080 FTW3 which is a power hungry beast with 3 power connectors. It runs quiet and a cool as a PSU should be. With PC components being hard to find since 2020 i still would not compromise on a high quality PSU.

    I feel like i wont have to upgrade for a good while after having this unless i get the new 40 series card but that aint happening. Also this psu is high quality so i know not to worry about it burning out or taking any of my parts down. Good buy

    Bought this because my old power supply didnt have enough juice and/or was dying on me. It was easy to hook this up and I thought I would hate having to individually connect all the wires but it ended up keeping my whole build very clean because I didnt use a lot of the other wires.
