The case I was building in was tight with my other Corseair 1200 and this solved the problem. Cable management made easy!

Very quiet under load. Silent when idle.
Side mount ports make for clean install. Make sure you have at least 1/2 inch of space between side panel and the PSU.
Cables are very stiff and do not bend easy.
Includes 12pin GPU cable for cleaner look with no need for adapters.
All cables are very long.

So far so good. I took a star off because it does not have a 12VHPWR connection and power cable, so I had to use an adapter for my 4090.

A novel take on the power supply with great IO.

I purchased this PSU specifically for its count of PCIe / CPU power connectors. I needed a minimum of 7 PCIe / CPU connections (5x 8-pin, 2x CPU). This guy has 8, which leaves me some headroom if needed in the future.
In terms of what this PSU does differently than others; depending on your case, having the power connectors on the side of the PSU makes for cleaner cable runs & more space. Another significant change in pace is that this PSU is equipped with Corsairs new "Type 5" cables. Which have significantly smaller connectors than before. I'm more or less indifferent to this change, if anything they seem bit more difficult to handle than the larger connectors. But they better match the new 12vhpwr standard. So, I can see why they made this change.
I very much wish that they included two of their 12vhpwr cables with a PSU of this wattage (1200w). Typically when you're buying a PSU of this caliber it's to run more than one GPU. It'd be less of a faux paw if you could buy an extra separately... but you can't. Corsair doesn't sell a standalone 12vhpwr cable in their new Type 5 form factor. I had to use one of the 12vhpwr adapters included with my GPUs, which felt bad, but isn't a huge deal.

Great power supply has its own 12v cable for 40 series video cards . Make sure your case has plenty of side room I have a large case and just barely got the side to close.
Could use more flexible and sleeved cables.

The side mounted connectors are an excellent idea meaning I dont have a birds nest inside my case as I can route them in a neat way.

Its an A-TIER power supply that is is fitted with enough cables to power a modern pc. The unit claims to use japanese capacitors that are capable of handling very high temperatures (which is excellent). The "SHIFT" feature can be restrictive in some cases. Make sure if your case has a sheath that covers the psu, that you can actually access the cables.
Currently runs my B650 AM5 motherboard with a ryzen 7 7800x3d processor and rtx 3070 gpu.

A hefty PSU for a hefty PC rig. I got this not only because of the capacity it puts out. But also because it has the cables coming from the side of it. Leaving space in front of it if you need an HDD drive cage.

The ports being on the side of the PSU make it very easy to keep cables tidy. Previously my Corsair 5000D had a huge rat nest of cables shoved in front, but it made it so much more tidy.
