    This being modular has made it very easy to keep my new computer build tidy. Having an 850W power supply has given me, more than anything, peace of mind, knowing that, even with the power hungry components coming out nowadays, I will never have to worry about this one being adequate or not

    Great psu, almost over kill. Just make sure your connections are all firmly placed inso you don't have to pull everything out again like me. Having the fullymodular version is definetely a must if you like keeping your pc clean inside, or change things out often.

    This a great power supply. It's probably more than I need, but it provides lots of capability for future growth of my computer system. It lopes along supplying the power needs of my system without showing a sweat. And it's just not that much more than lesser power supplies.

    I upgraded my power supply just so it could handle everything I was getting ready to put into my computer build. This power supply is GREAT! It is not loud at all and the modular wiring is everything you will need and then some! I would definitely recommend this to anyone!

    It's still kicking. I think I'm a Corsair fanboy now. I have 5 NVMe drives, 7 HDD Drives, GTX 1070 ROG and 12C24T Xeon hooked up with 64GB RAM. This thing doesn't break a sweat. I've burned 3 EVGA 1600 Platinums. This one is handling it much better!

    Picked this up to use with my RTX 3090 FE. Quiet little power supply, does the job just fine. No hybrid mode like my Seasonic and the cables are a little thick and hard to work with, otherwise it does everything you'd need a PSU to do. A-tier on LTT's tier list for a reason!

    The PSU itself is great, no issues so far. It's very quiet, the fan doesn't even need to run. The cables are a little tough to work with, very rigid where the heatshrink is. I recommend getting Cablemod cables or the pro cables, but that adds a lot to the total cost.

    Quiet, Modular, Cords could be better

    The PSU is extremely quite; I am more likely to hear my CPU/GPU fan than the supply. Although I won't need them now, the availability of additional cords is nice if I choose to upgrade my PC. The cords were a bit of a hassle (and not pleasant visually), but does the job.

    Build quality is above par. Went from a EVGA to this and very pleased. More than enough cables and connections to run anything you need. Was surprised with a nice cable bag to keep all the additional cables for storage that were not need for the initial build.

    Hands down this is the best version of the AirPods by Apple. I will go even further to say of current True wireless headphones. The design tops that of all previous versions. The transparency mode is the beat feature I’ve ever encountered on wireless headphones. I have average size ears, so the stem of the AirPods do not past my earlobes. They fit very well. The only draw back is no volume control but that’s not even an issue when you can just say “hey Siri” reduce my volume to 50%. To give you a better vision of the transparency mode; I live near the Ports and an airport. With transparency mode off I can barely hear the horns blowing while I’m outside. With it off it sounds as if nothing is in my ears. If your looking to get any other version of the AirPods it’s my honest opinion spend the extra cash for the pros. Otherwise your going to fine yourself investing in them later anyway.

    Fantastic power supply that you can definitely trust. Corsair is truly the only company that i feel gives the best protect in terms of power supplies. It’s nice and quiet, and the fan doesn’t even spin until under a heavy load, meanings it’s unbelievably quiet

    Awesome power supply, the white housing really does pop and comes with white cables to match. The Corsair RMx series are some of the best rated gold power supplies you can buy. 850W is more than enough for the RTX 3000 series or the RX 6000 series of GPU's

    This PSU works perfectly and is very quiet in my case. I power everything fine and is easy to set up. I like how you don't need software to handle this thing because it easily handles itself and you don't really have to manage it. (Except for cleaning the fan periodically)

    There's not much to really say, it's a quality PSU from a quality brand at a great price. I like that it's modular so I don't have a giant snakes nest crammed in the bottom of my enclosure. Voltage outputs on the motherboard are solid all day. Would def buy again.

    It is durable runs fairly quiet with a constant load of 500 watts. I use this to mine coins. This will go into a threadripper build that will use 1 amd threadripper 3970x cpu and 1 amd 5700 gpu. It will use about 400 watts and run 24/7/365. Note that the price was nice.

    Quality product and its weight tells you that it is made of good materials. We replaced the graphics card in my son's gaming computer and was advised that the prior power supply would not be sufficient. Was in stock at the local Best Buy and so far, no problems and very pleased.

    Great Power Supply with Gold Rating. Running it with my fullliquid cooled Ryzen 9 5900x and RX 6800XT. Full ASUS ROG STRIX build has no issues and plenty of power. Graphics card requires at least a 700W power supply
