    This has been working greatly in my PC. Definitely a lot more quiet than my previous part. I'm glad I replaced it!

    My 2nd RM series PSU in a month, on 2 different PC's. This was a preemptive purchase replacing a CX with a C+ on the SPL rating. This one is in the B range. Very quiet. The cables are amazing. Only con is that to have 3 PCIE connections, you have to use the dreaded 12V connection to split out into 2 standard PCIE connections, plus 1 of the type 4 units.

    it being modular makes a big difference, the wires are nice and it comes with one of the new cables that you can plug directly into your GPU instead of plugging three cables in into an adapter

    I purchased this power supply as part of a PC build to get on Windows 11. It's been rock solid and quiet. Also, the fact that it came with so many cabling options, specifically for video cards was very helpful. While it doesn't have a lifetime warranty, a 7 year warranty seems sufficient for aging this computer to the point where I would be looking a doing another refresh.

    very easy to install, just a simple plug n play setup and only need 1 feed wire for the GPU which is very convenient.

    This PSU is super quiet. No whirring noise and the cables are super easy to cable manage. Power cable is also pretty long just incase you have to reach for an outlet.

    I upgraded to this from a 650W PSU as I needed a bit more power for my 5070 Ti. I was worried it might be noisy, but I haven't heard a peep out of it since installing it. I'm not sure the fan has even come on once. It's pretty compact so there should be no issue fitting it in most builds. The cables are a nice change of pace. They're not quite braided, but they're not the usual rubber cables you see with other units. It's also nice they include a comb to keep them neat. Happy with my purchase!

    Bought this to replace my faulty msi power supply that the fan went out on after only less than 5 months. This thing is extremely quiet and does not have any vibration at all. it does make a single click noise though when you turn on your pc not sure what thats about but when its running i dont hear it at all.

    I replaced my stock psu with this one. It is so much better. There’s also more room since I only use the necessary cables.
