    The fan doesn't kick on much for my use. It's quiet, powerful, and modular! The only thing I didn't like are the cables. It's stiff and hard to curve around corners for cable management.

    was looking to upgrade my 400 watt so I seen this one on sale. Been running it for over a month and I have yet to hear the fan. I put it in a nzxt 500i case.

    I needed a more powerful pay to replace my 10 year old 500w unit. For a few more dollars than the entry level units this one includes very high output, quality Japanese capacitors, a super quiet fan, and fully modular cables so you only have to use the ones you need. The RMX series is a substantial step up in efficiency and quality from the lower line.

    Picked this up to replace a failed power supply in my desktop PC. I've never worked with a modular power supply before and I don't believe I would ever go back. The powder black housing looks good and you only install the wires you need. A little planning and a few small zip ties and you have a clean professional installation that looks high end! Also, this power supply is very quiet providing peaceful computing. My last power supply sounded like a prop engine plane getting ready to take off (probably why it failed.) I only used a little less than half of the wires provided, so connectivity isn't a problem with this unit.

    Runs quiet fan rarely ever kicks on, I run a i7700 with a 1080ti and most of the time the fan does not run. Full modular helps with cable management. Highly recommended

    Well to start of I gotta say my favorite thing about this Power Supply is that it is 100% modular. I have bought Power Supply's in the past that were "modular" but at the very least the 24 pin motherboard harness would be connected in a way that it cant be removed. Obviously most people wouldn't remove that because its essential to a computer, but its nice to be able to do it. I dont knowaybe swap out different kinds of wires. As far as performance goes, it is powering my i9/2080 rig with all the bells and whistles with no sweat at all. Corsair is a QUALITY brand imo!!!

    Ppl actually overdo the psu thinking of upgradeability, but this 750w gold rated is doing just amazing on a setup with like 12 fans, a ton of rgb strips, rtx 2080, i7 9700k overclocked, 32 gb ram, water cooled, 1440p monitor and a ton of extra peripherals 10/10. I bought aftermarket cables since it is fully modular, the stock corsair ones are a bit too stiff imho and look as good as me with a hangover (not good, just functions)

    The first thing i though when I opened up the packaging was wow, nice case core the modular cables, but then i looked at the actually Power supply itself and it came in a velvet case. I see no real need for this as once it's inmy pc it's going to live there. I imagine i can repurpose it for something else and maybe that is there hope since it has brand info on it. Modular design allows you to leave of cable you don't need resulting in less case clutter. The cables including cpu/mb and video card were all long enough to reach in my full size case and MB. Performance has been great as far as i can tell. I have tried to measure power draw or anything but it's been quiet and no issue with the blue screens or anything else. Overal I'd def recommend this porduct

    worked great on my previous build, so I decided to use it on my new build powering a 3700x, strix b450 f gaming MB, ddr4 16 gigs, on a cooler master h500.. works as expected and gold rated for better efficiency! Fan hasnt turned on even during intense gaming periods. Will buy another on my future builds.

    Being the unit is a bit longer than my old PS I made sure it was going to fit in my Dell mid tower case before I purchased it. Having the modular cables is a big plus since they are a bit bulky and were fun to fit in only the cables I needed. It runs great and is so quiet.

    Comes in a cool bag and had more than enough cables (to be expected with a modular PSU). Nothing felt cheap and it has a factory warranty corsair usually gives on all of their products which they've stood by.

    This unit probably has more power than I need. The cabling was relatively easy to work with and it is doing a good job. Seems quite quiet.
