Customer Ratings & Reviews

Excellent product. It powers my new 12900k/3090 build flawlessly. I've never had a corsair product let me down, let alone one of their power supplies. I would highly recommend for anyone looking to add some extra juice to those power hungry components.

Great power supply. I have always used Corsair power supplies and never had a problem with them. This should and be last power supply hopefully I will ever need. You can’t wrong with Corsair power supplies.

Got it on sale for $245, great value! It's Corsair so you get quality and the 10 year warranty. Pros: - Silent - Platinum - 1200 watts - High quality sleeved cables - Multi/Single rail switch Major Con - Only 4-5 PCIe ports available, since 1-2 will be used for CPU which is a little disappointing with the rumored Nvidia RTX 4000s PCIe/power requirements Minor Cons - "Stiffness" in the power cables can make them slightly unwieldy depending on configuration. - Not a fan of the "loop" dual PCIe connection - No 5th PCIe cable included, Corsair recently restocked but it took a while

This is my second HX 1200W I've purchased from Best Buy - works like a charm. Corsair PSUs have never given me any issue unlike many, many other manufacturers.

For the price you can't go wrong. The modular cables make it so much easier to route cables from the components to the PSU instead of the other way around. Plenty of power.

Amazing PSU. I own three pc with the same power supply. Lights can flicker or go out for half a second and the pc is still running. Has never given me problems in all the years I've had them.

Unneeded, but needed. Great psu if u want high end and somewhat future proofing. I do recommend getting corsairs custom cable sleeve though as the main cables are stiff. having 3 8 pins in my 3080 just looked terrible.

So far, this PSU is a beast. I pull around 650-700watts while playing video games. Plus plat PSUs allow you to do more while pulling less wattage. Well worth the cost.

Just here for the points but the psu is great, slightly on the expensive side but works amazing in my $3000 build.

I am 100% satisfied with this PSU. Running an overclocked Ryzen 9 5900X and an overclocked XFX 6900xt black edition with no worries or issues.

Very large! Would have had to remove my HDD trays in order to make the cables fit. Ended up returning it instead and going with the 1000W option.

Corsair, need I say more? Easy installation and modular. Makes cable management a breeze.

Works great with my dual 3090 setup. I have enough power just to add a 3rd when I get another card

A really beast power supply and a good quality from corsair, I have most of my pc parts that its corsair, recommended brand

So far so good, powers rtx 3090, i9 9900k no problem. Haven't detected any coil whine and is silent. 5/5

I love that most corsair power supplys use all the same cables. I had an RM850x in my PC but when I did that math that adding a 3080ti would put me dangerously close to 850 watts I knew I needed to upgrade. The great thing was that I could leave most of my cables in place and just plug then into this PSU. As a warning, do check the following site if you are considering doing the same, do check corsairs website for PSU power cable compatibility. Happy building!

These seem to be of great quality. It was surprising to see it on and running and not even needing its fan to be going.

Exceeded Expectations! I should not need another power supply for years. This power supply supports any motherboard I will use in my PC for the foreseeable future.

My PSU was overvolting my setup and during the rebuild, i chose this unit as its repalcement. I lvoe the modulatiry, clean install and abundance of the cables included.

Great power supply that is reliable and ready to keep you going for years to come!
