Corsair offers a wide range of power supplies, and the HX series are near the top of their quality spectrum. These are very efficient, work silent (no fan during normal operation), and overall are very good for the health of your PC in the long run. I personally purchase the HXi series for higher loads, and the competing EVGA Gold for others. HX series is in between the two, giving slightly better efficiency, trading off on size and price. There are basically three reasons to go for a platinum PSU. First the efficiency, however this would be my last reason in practice. Then the features, like modularity, and most importantly the build quality, which affects the warranty, and of course the power quality your motherboard and other components receive. The last one is very important if you want to keep a stable working PC for a long time. Going into details, the efficiency of 80+ Platinum PSU are peaked at 50% load, and 240V of power. To give some perspective, if you have a recent PC with an I7 or Ryzen processor (about 120W), and a decent GPU (let's say 1070 at also 120W regular 160W on load) your total load, including other peripherals will be a tad under 350W if you are not overclocking. If you get the HX750 model, you'd then be drawing about 380W from wall at 92% efficiency (with 120V). If you have the average US 12c/kWh rate for utilities, and use the PC for 8 hours of gaming a day, you'd be looking at a power bill at about $135 per year of usage. If you were to go with a 400W bronze PSU, the bill would go up to $150. That's why I don't recommend going to platinum PSU just for efficiency, but there are much better reasons. (Exceptions are if you're unfortunate to be in PG&E service zone with 45c / kWh rates, and need to use 4 GPUs for 24/7 machine learning tasks, or just crypto mining, then the bill differences would be in hundreds of dollars). The main advantage is the quality of the parts. Most PSU will work fine under moderate load with clean power coming from the wall. However things change under heavy load and/or power issues, especially brownouts, which will not be caught the surge protector. You'd want to avoid them, hence get a more expensive PSU. One way to measure the quality is looking at the warranty length, for example this one has 10 years, which tells a lot about how much Corsair believes in them as the manufacturer. The second advantage are the better features. Higher end PSUs, like this one will offer modularity, lots of connectors, a silent fan, and sometimes monitoring options. Believe me, modular PSUs are in a different league than the old style ones. For example I have a small PC as a router, which is cramped, but only needs a few connectors (since it only works as a basic router). Having a modular PSU saved a lot of room inside the small box. Also at the top of the line the HXi versions, which I personally prefer over the HX series, comes with a USB connector to the motherboard, which will allow you to monitor the power level of individual ports. This is very useful if you are into overclocking your system. I have built many PCs (some upgrades, some for friends), and Corsair is one of my go-to manufacturers for PSUs. These work well, has lots of features, and have great build quality.

Had a AX1200i that was shutting off. Looked up compatible cables so I wouldn't have to rewire my entire PC again, and found out the HXi shares cables. When I got the unit, it actually had a different motherboard connector on the PSU, but luckily, I'm already using a Motherboard 24 pin + 8 pin extension cable, so, all I had to do was swap the motherboard cable with the one provided, was simple. Everything works again.

I bought the HX750 to allow my PC to be more power efficient, as the original PSU, an EVGA 850GQ (which still works perfectly fine!) was in use for over 6 years and was slowly starting to show its age. The other side of this batch of upgrades included going from a Ryzen 7 3700X to a Ryzen 7 5800X, then a GTX 1080 to Radeon 6700XT, and then bumping from 16 GB 3000 Mhz C15 to 32 GB 3600 Mhz C18. This sucker has been running both under full load without overloading and runs unbelievably quiet while doing so, kudos to Corsair for that level of design. As an added bonus my PC has had significant improvements in overall power efficiency. The only thing I honestly didn't like was the price, a$40 price difference between the Gold rated RM750X and the HX750. But after seeing how much it improved my PC's power efficiency it's proven itself to be worth that extra $40. If you are looking for a decent 80+ Platinum PSU this is a strong contender despite the price.

my 3rd PC build always been with same brand PSU in last 15 years. Never have had bad experience, I can confidently recommend this to my co-worker and to any of you researching for quality PSU. Indeed price little bit higher than any other brand but for quality and performance you get what you paid for. My 15 years old PSU still up and running until today. Pros: Power-up at first boot. Handled my Ryzen 5950x and NVIDIA FE RTX 3090 just fine and plenty of power Quality/premium build Cons: Typical ugly cable, Not really Cons actually it does the job. Personally willing to pay extra for nice braided or throw some LED maybe. Would be helpful if it have LED showing power is on. No indicator or whatsoever I found it hard for first time builder to troubleshoot when PC not booting up. I have some case, my client almost throw away his PSU due to not knowing which part of component not working at the time of build.

Great power supply I should have went with corsair to begin with, I bought the evga supernova 1000watt and ended up having nasty coil whine sounded like electricity was arcing inside of it and got worse with more load I couldnt stand it so sent it back decided to go with this one even though its technically not as powerful it has the platinum rating compared to the evga which was gold. So far since ive had this unit I dont get any coil whine sometimes i may hear a very faint noise from it but honestly all power supplies will have a very small amount of coil whine as well as gpu's when you are running at full tilt and high fps. The only Cons I can find with this unit are the cables they need to be a tad bit longer and theres heat shrink like half an inch from the connector which makes it very stiff and hard to bend especially the atx power cables for the motherboard.

Runs my desktop with a Ryzen 7 5800X3d, Nvidia RTX 4080, 280mm liquid CPU cooler, 6 case fans, 4 Nvme SSDs, 64 GB of RAM and case lights with ease. Fan is quiet and I hear nothing that others refer to as coil whine. Only thing is that it doesn't have the new 12 volt connector that is used on the Nvidia high end cards so you will need an adapter, which may not be a bad thing if your connector fails on your GPU, at least you will only have to replace the adapter harness if it damages the harness connector plug.
