I have this one, put it in a Corsair 5000D case. It was very easy to connect and route the cables. I highly recommend it if your case has the side space.

The info above is great and that's what I did. The 1200W was overkill for me, so ended up getting the 1000W instead straight from Corsair.
Here is some additional info that might help others...

I just got a 1250W Gold power supply with a 10 year warranty from NewEgg. It was like $60 cheaper too. Might wanna pass on this one.

Last Corsair PSU I bought had a terrible coil whine... ended up returning it to Best Buy and went with a Seasonic from MicroCenter.

I own this PSU and its fantastic. I have a 4080 super, 7950X3D, 4 m.2 nvme drives, 2 SSDs, a thunderbolt card and quite a few case RGBs and advanced fans. I plan on upgrading to a 5090 when it is...

I have this and it’s been great. The 1000w wasn’t available at the time.
The best thing about this is how easy and clean it makes cable management. It’s a must have for those with OCD like me...

Realistically you should calculate real world electrical usage based on the 80% rule so this would be around 960w with is about right for a high end system with multiple components

Just want to point out that I have a 4080S and a 5900X and I have plenty of headroom with a puny 750W PSU. yes it's a top tier 750 but still only a 750.
So unless you are planning to run a lot...

I have the 1000w version and it has been solid. Only gripe is the connectors are type 5 which are only available through Corsair or cable mod if you want to replace. The ones that come in the box are...

Considering the technology advancements and trends for the past decades, I doubt we will see 1500w becoming the standard anytime soon.

When all PSU brands hit the 1500w limit, it's gonna be wild. Prices are gonna get all out of whack and anything lower than 1500w (in the U.S. anyways, UK and EU is higher) will probably be obsolete,...
