    No complaints yet as I bought this when I was upgrading my wife's computer, being modular is awesome only using the power cables you need to reduce the clutter, so if you need or want to upgrade and this is able to fix your power needs, go for it.

    I was having problems with the drives in my motherboard Raid Array getting out of sync. I determined that my original power supply was not able to power the extra drives added to the system. This power supply has worked flawlessly powering 6 internal and 2 external drives. The flat power cord for the drives makes a clean installation.

    Its a modular power supply that us 80 plus bronze. And basically the better the rating the better the power supply. I got this for a mid tier build that doesnt need anything crazy and its modual which means only the cables i need plugged in, not every cable in the box. And its corsair so we know its a quality brand!

    The power supply was easy to install. The modular hookups made connecting everything a breeze, and I only had to install the supply wires that I needed. Cable management was easy due to the sheathing around the wire bundles. I can't find a bad thing to say about this power supply after a month.

    I had a power supply give out on me a few months I had bought secondhand. My brother recommended that I’d get a Corsair PSU. Dispute, all the negative reviews on forums, he said this was a newer version of the old CX-M model. I got the PSU, had his help put it in, and my pc worked again!

    This PSU provides adequate power for my PC build. I have a middle of the road set-up. Besides the motherboard, I have a GPU, two NVMEs, four SATA drives and four fans hooked up to the PSU. It's been working well so far.

    This particular power supply provides ample power for older and newer systems. Its modular design not only helps with cable management, but Power delivery is well. With a smooth powerful solid state system this power supply is well made and I expect it to last a long time with a 5 year warranty I wouldn't choose anything else.

    Performs as expected, as of writing, (3 months after purchase), I have had no issues with it and my computer is running great. I wanted the fully modular version (RM650X), but due to the low stock during Black Friday week, I was unable to get it. Pros: - Computer hasn't blown up - Quiet Cons: - Cables are very stiff - hard to cable manage - No cable ties so my 24 pin connector looks awful

    This is one of the few PC components that you can go and get blindly at Best buy and not worry about price matching or anything. I had to get a PSU to finish a system in a hurry and had no time to wait for deliveries. It's true that you could find 80 + Gold close to this prices, but the Corsair quality and convenience of having many best buy store close by are worth getting this one. I have bought this same model more than once and so far they are working great.

    Your modular power supply works great. I was a bit tired when I put my computer together tonight so I didn't get to really test it out but I will update this as soon as I do. Thanks for having a good power supply available for those of us who still build our computers.

    I bought this power supply thinking it was going to be very expensive but when I go to the store was actually fairly cheap. When installing it on my computer I had little to no problems, there was a port for everything I needed. Even with my computer being a little older.

    Time to upgrade my home PC to the latest technology. Bought this power supply to supplement the requirements of the latest GPU. It works great with no issues. I love the modular aspect as it is so handy in routing cables inside a small case.
