This Corsair HX1200 has been rock solid in my build. It delivers clean, stable power and runs extremely quiet even under load. I barely hear the fan, which is a big plus compared to my previous PSU. Cable management is easy since it’s fully modular, and the included cables feel high quality and flexible enough to route without much hassle. Installation was straightforward, and it’s been completely stable with a high-end GPU and CPU combo. It’s definitely more power than most people need, but if you want headroom for upgrades or just want something that will run efficiently and last, this is a great choice. Expensive, but worth it for a premium build.

Good modular PSU that works admirably in high-wattage situations. Never had an issue with it overheating or even in general. Very quiet. Being able to only use the cables you need is great for keeping your case clean and managed. No issues with fit in a normal ATX case.

Coming back 8 years later to write a review on this. I really didnt need this powerful of a power supply, but honestly, after nearly a decade and this thing not once failing on me or giving me any doubt, it was well worth it. Installation was easyish, it has many ports on it because you can run multiple GPUs to it. Not the quietest but honestly who cares when it lasts you this long. If it goes out, I'm buying the same one again. Something tells me though that this bad boy isn't going anywhere anytime soon. Here's to another decade!

It's been working well for the past month or so since I bought it and under heavy load without turning it off at all. I had some problems turning it on at first but it turned out that one of the HDDs was not getting along with it for some reason even though I just replaced this one with the other one I had before without changing anything else. It was turning on and after few seconds it would shut down on its own. The HDD that was causing the problem was not the main one it was just an extra one. It took me some time figuring what was causing the issue but all is well now and after replacing the sata cable of the HDD causing the problem it worked out fine. Looks like the cable went bad or something when I put this new PSU in.

Works as intended. Came with a bunch of modular parts which is nice. Fits well in my case and has served me for over 2 years with no issues

The HX1200 comes with listed cables and ports. Also has a really stylish drawstring bag for the PSU and a Velcro pack for the cords, which are bundled with plastic coated twist ties. Cables (except SATA) have an interesting braiding. Includes a handful of black cable ties for cable management and a Corsair sticker. Says it comes with a 10 year warranty, so I anticipate it should last a very long - that would make this the most worthwhile PSU purchase you can make for never needing to get one for a long time. This PSU is overkill for just about any consumer grade system - you can push the most power hungry overclocked CPUs and graphics cards in SLI/Crossfire, never have to worry, and still get fantastic power efficiency with almost silent operation (dB output is based on load, so lower load means lower noise, but full load is only ~20-25db). That being said, the RM1000x could boast similarly, but it would be an awful shame if your system draw was slightly over 1000W and you had worry about hardware failure. I bought this on sale, so it was only $40 for better power efficiency, more silent operation, and an additional 200W cap. Otherwise Link compatibility or perhaps regular pricing would make it less worth the jump. I can't know if it'll perform to specification and can't currently measure it's actual output. I can only hope that this thing will be more than enough for whatever I decide to throw at it for a couple handfuls of years. Only weird thing I noticed is that the CPU/PIC-e 4x4 cord has an inflexible tape-like extension on one end, which makes sure you connect the secure clip to the CPU power header, but this matched with its standard length makes it such that you can't have very creative cable management, at least with my ATX motherboard with a Corsair 750D case, where I was only able to route the cable one way due to length and flexibility. Did not end up being a "problem" though.

Be ready to purchase extension cables for the CPU and motherboard connections, unless you have a top mounted PSU, don't care about cables in front of the motherboard, or have case smaller than standard ATX. The in-line capacitors are completely in the way and they didn't increase the cable length from the older generation cables. To safely bend the cables to route behind the motherboard takes a large portion of the total length; making it impossible to reach the PSU. Even when routing the CPU cables in front of the motherboard and removing the shroud, they barely reach and have to be tied back with straps so they don't rest on critical components. If you don't vertically mount your GPU, you'll have a similar problem as the case cover will force you to put extra tension on the cable so the cover can be closed. I suspect this will be even more of a problem once I need to use the new 12V connection on a modern card, as they are more dangerous if bent at the socket. Also, the detached 2 pin portion of the PCIe cable won't stay seated in the card unless you make the initial bend toward the the 2 pin side. Corsair sells thinner, single wrapped, replacement cables for another $100, but they are just as short. It's ridiculous that at this price point the out of the box experience is substandard. This could have easily been fixed by adding a few more inches of cable and possibly throwing in some 90/180 degree connectors to shorten the distance required to safely route cables. It wouldn't increase the substantially and the user experience would be so much better. I can't understand how this design has been in production for so long and this hasn't been addressed yet.

It has powered my pc for the last 8 years and still going strong and could go for even more, can withstand top tear GPUs without a problem, only downside is it's not going to fit every case out there, because of its long shape.
