    Very good build quality. Has all the cables you need. They are a good length as well. Installed it about 30 mins as I also zip tied the wires for a cleaner install. Just replaced an antec 900 hcg that i purchased i brand new 2012. Supposedly has a zero fan rpm mode But I cannot see it. The price point is good compared to others. Has a 10 year warranty.

    I bought this for my rtx 4090. This PSU paired with the Corsair 12vhpwr cable makes for a much much cleaner build!

    I really like the power supply and Corsair is known for great products. Where this falls short in my opinion is in the PCI-E cables for a GPU. Instead of being individual cables they each have a linked extension at the end. In my case I have a 3090 and I wanted to use an individual cables for each 8-pin plug but instead it looked like a mess because of the linked extension. If you don't need that many 8-pin plugs this is a great power supply.

    Not for cable management

    Haven't completed the install and don't want it already. No flat cables like it's 2015. PCIe loop makes it difficult to install cover without bending the cable. CPU had to be diagonally installed to reach its place (short)

    Was building a new pc setup, got this psu cause ive had a great time with corsair products. Had everything set up and went to boot up my pc for the first time and…nothing. Tried trouble shooting everything i could for two days, eventually took it to a shop to see if they could figure it out., turned out to be a bad psu, no problem, went and got it replaced, and… nothing again either I’m unlucky or the build quality on the rm1000x is garbage. Very displeased with this product.
