Great power supply. This is the second Corsair power supply I’ve bought in the last decade (my other one is still running strong in my back up pc). I’ve had zero issues from either one. Would absolutely recommend

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.

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

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.

This thing is built very well and is very quiet in my opinion. I do not doubt that it'll outlast it's warranty by a good way. This is more than I can say about some other parts of my PC rig. These days with the 40 series being as power hungry as it is I'd say that this is about the standard amount of wattage that people are recommending. People just a few years ago told me I was crazy for buying a PSU this big for my 3090. Look who was wrong... Anyway, I highly recommend this PSU although a lot has changed since I bought it so there may be other good options out there by now as well. You can't go wrong with Corsair (from my experiences at least).

Replaced Corsair RMX 1000W power supply with this 1200 variant. My 1000w power supply had a load at the outlet of 1034watts, so I new I needed to upgrade. Without any other changes to my server rig, other than the power supply replacement, my at the outlet load is now 845 watts. So this must be a highly efficient unit and a reminder to size your power supplies correctly for your work load. this power supply is almost two inches longer than the RMX 1000W, luckily I had room but the modular cables are more difficult to route and get out of the way for good airflow. Makes no noise, even at load with its fan at a high speed.

I bought this power supply to power my RTX 3090, i9-10900k and various other rgb fixtures in my pc. So far since building my pc I haven't had any problems with it. I don't hear it even under a heavy load. No compaints on functionality, but asthetics - thats a different story. The power supply itself is not where my problem lies, its the cables. The cables are so thick and have the ugly netting type material around all the cables with the shrink wrap around the ends. I wish they were more of the flat black cables. I am certain the case I decided to build in didn't help manage the cables, but over all I feel my experience with this power supply would of been better if the cables were kept in a different material and tad more flexible. Cable management was the biggest pain trying to get all the cables to fit behind the motherboard tray. Overall, I can't complain about this power supply. Quality seems to be there, but if you care about looks I would maybe look for a different power supply or get some custom cables. Power supply 10/10, cables 3/10.

I've had it since Dec 2022 and it hasn't shown any issues whatsoever. In it for the long haul! I'm using this in a pretty beefy setup with my 4090 FE, plenty of lights, fans, etc, and it functions exactly as intended. The whole product feels extremely high quality, the cables aren't that cheap rubbery material but the nice threads. There were plenty of extra cables I never ended up using, but the packaging is quality and the extra cables came with a bag just in case I ever decide to use one.
